Smaller than a T-Rex, the Gorgosaurus was Faster and Hunted in Packs

by Emily Rodriguez Lima, age 13

There was a dinosaur named Gorgosaurus that was discovered a few years ago. The Gorgosaurus is a relative of the T-Rex, but were smaller, with a stronger bite and faster speed.

Like many other dinosaurs, the Gorgosaurus had muscular legs. Scientists believe that their legs helped them move at faster speeds considering how big they were. The speed of the Gorgosaurus was around 30 miles per hour. Its adult size was 26 to 30 feet long with a weight of three tons. During the Cretaceous period, the Gorgosaurus lived in what is now the United States and Canada. This creature’s name came from a Greek word, “fierce lizard.”

A notable feature of the Gorgosaurus was the two horns on its head. Their horns were used simply for display since they were useless in battle. Their hunting consisted of other dinosaurs that ate large plants, such as the ankylosaurus, hadrosaurus, and ceratopsians. [read more]

What Brought About the Extinction of the Megalodons?

by Jason Medina Ruiz, age 11

Megalodons, an extinct species of mackerel shark, were the ocean’s biggest predator for millions of years. The appearance of great white sharks brought competition to the megalodons. It is a popular theory that great whites were the reason for the megalodon's extinction.

To know what megalodons ate, researchers looked for zinc in the sharks’ teeth. There are two types of zinc, or isotopes, zinc-66 and zinc-64. The isotopes on the teeth are used to understand what kind of food these creatures ate. Animals that have a diet of plants have more zinc-66 than carnivores, who have more zinc-64. Both these shark species evolved to have higher levels of zinc-64. The great white shark and the megalodon had the same diet, consisting of marine mammals, such as seals and whales.

The megalodon was the largest carnivore to ever exist and it grew to be 46 feet long. The megalodon probably went extinct from the changing ocean and a large drop in marine mammal population. The reason why and when they went extinct has not been fully answered. The species is believed to have gone extinct either about 2.6 million years ago or 3.5 million years ago, at the time great white sharks appeared. Competition with the great whites was suddenly fatal, but possibly not the only reason why megalodons disappeared. Continued research is being done to better understand the history of the megalodon and its eventual extinction. [read more]

King Cobra vs. Mongoose: Who Wins?

by Jonah Smith, age 13

The debate about the king cobra vs. the mongoose is a long-lasting argument about which animal would win in a fight. Some people think that the king cobra would win while others firmly believe that a mongoose would be victorious. A king cobra has an extremely venomous bite that can kill up to 11 people! On the other hand, mongooses are very agile mammals that also hunt snakes similar to the king cobra regularly.

When it comes to size, the king cobra has the advantage. It grows up to 12-19 feet long and weighs up to 15 pounds. A mongoose is only one foot tall, and it weighs just 5-11 pounds. However, mongooses are faster. They can move as fast as 20 miles per hour and are able to swiftly change directions.

Although the king cobra may appear scary to its prey, it does not scare the mongoose. The mongoose knows that because it has thick fur and strong skin that naturally repels the king cobra’s venom, it is not threatened by it. Lifting its body in the air, the king cobra can imitate “standing.” When it does this, it will hiss at its foe and spread the hood on its head. The only thing keeping the king cobra safe in this stand-off is its size. [read more]

We Bet You Don't Know About this Hyena!

by Dayanara Flores Gonzalez, age 14

You might think there is only one type of hyena, but no, there's more! There are two different types of hyenas: brown hyenas and Aardwolf hyenas. These hyenas look like dogs, but they are cat-like carnivores. A carnivore is an animal that only eats meat. Brown hyenas can easily digest skin and bones with their sharp teeth. They scavenge for lions that have previously been killed by other carnivores or hunt for their own prey.

Aardwolf hyenas, named for the Afrikaans word for “earth-wolf,” are insect eaters. They use their sticky tongues to pick up insects and use their teeth to harvest more than 200,000 termites per night.

Hyenas spread through the Middle East and South Asia; they can be found in grassland or savanna habitats. They live in clans of 80 or more, sharing the same home. Hyenas also have elaborate scent marking rituals. This helps them familiarize with each other and maintain their social systems. Hyenas sniff each other's heads and bodies, which can engage them in ritual fighting. Hyenas spines slope down towards their tails. [read more]

Birds, Bees, and Butterflies: How Butterflies Meet and Mate

by Dulce Maria Vasquez, age 14

Butterflies live for a short amount of time, which means they have to find a partner quickly.

Female butterflies only live for a few days, therefore they have to lay their eggs as soon as possible. Male butterflies come out of cocoons faster than females. This gives males an opportunity to find a mate who is newly emerged, meaning the females’ wings are flimsy and shriveled. Females and males correspond with each other based on their wing shape, color and striking patterns. Usually female butterflies are lightly colored while males are brightly colored.

Male butterflies often flap their wings: this may seem like they are showing off but in reality they’re wafting pheromones. Male butterflies mate a lot of times during their lifetime, while a female only mates at least once and then starts egg-laying. [read more]

How Fossils Detail the Evolution of Mammals

by Dayanara Flores Gonzalez, age 14

Have you ever wondered where mammals evolved from? Mammals come from something called synapsids. The pelycosaurs were the first synapsids.

Pelycosaurs had different types of teeth that allowed them to be plant eaters or carnivores. Pelycosaurs had a thin piece of skin on their backs called a sail. This sail kept them cool or warm depending on the temperature. The pelycosaurs became extinct and were replaced by a group of synapsids called therapsids.

Therapsid fossils were found in red sandstone in South Africa; they were discovered in the 1840s. Cynodonts are a type of therapids that were around during the Permian age. Cynodonts had shorter tails, powerful jaws, diversified teeth, and knees that flexed forward, which was the first evidence of resemblance to mammals. Before becoming extinct, cynodonts survived through the Jurassic period; they lived among dinosaurs. [read more]

Learn About the Unique Jackson's Chameleon

by Moore Vang, age 13

The Jackson’s chameleon's name comes from the words “chamai leon” which in Greek means “dwarf lion.” This refers to the aggressiveness of a Jackson’s chameleon when it is threatened. It is mainly green but can camouflage to the color of its habitat.

The body length of a Jackson’s chameleon is 6-12 inches long and it can weigh up to 1.5 lb. It has three toes on each foot that have a clamp-like grip which helps support its body on trees and branches. It also has a long tail that is able to firmly grip onto the branches which also supporting movement. The skin cells of the chameleon contain pigments that can change color. Depending on the mood, it can turn pale when relaxed and dark when annoyed.

The Jackson’s chameleon lives on the East African highlands in places like Nairobi and Mount Kenya. It commits itself to living in forest environments and lives there for its entire life. In this environment, it can survive different types of weather conditions and temperatures as low as 41 degrees Fahrenheit. When provoked in their habitat, their first instinct is to camouflage within a few seconds. [read more]

As Ice Caps Melt, Polar Bears in Greenland Adapt

by Emily Rodriguez, age 13

Natural icy habitats of polar bears have been destroyed by global warming over the last few decades. However, there has been a group of polar bears that has learned to adapt to these conditions. Surprising scientists, polar bears in Greenland have been resilient to the ever changing climate of their glacial environment.

The ice in the Arctic is melting bit by bit. As a result, polar bears' food resources are being more scarce and harder to find. Seals are one of their main food sources in the Arctic sea. When they live on land, their other food sources are small birds and plants, which aren’t enough to feed them. Polar bears are now finding alternative ways to hunt seals on glacial ice.

A scientist at the University of Washington, Dr. Kristin Laidre, tracked some glacier-dwelling bears with radio collars. Dr. Laidre and her colleagues studied their DNA. They tranquilized them with darts fired from a helicopter and removed tufts of fur for testing. They collected new data every seven years and also used 30 years of prior information. [read more]

Don't Be Afraid of Every Coyote You See

by Dayanara Flores Gonzalez, age 14

Have you ever seen a coyote in a Madison park? Well you're in luck because it might not be real! These coyotes are made out of plastic and faux fur; they are also a new addition to the Canadian goose management program.

These coyotes can help scare off geese and also help with keeping geese poop out of parks and beaches. The faux coyotes also stop geese from breeding and increasing their populations.

Not only are Madison parks using fake coyotes but they are also using strobe lights and asking volunteers to scar egeese away. Geese are also being put down to lower their populations. Some people do not like this method, in 2011 a group of protesters held a funeral for geese that got shut down that summer. [read more]

Learn About the World's Smallest Elephants

by Ashley Mercado, age 13

The Bornean elephant is the largest mammal on the huge island of Borneo. These elephants are also known as Borneo pygmy elephants because of their size.

Compared to other elephants, Bornean elephants have larger ears, straighter tusks, and are smaller in size. In fact, Borneo elephant tails sometimes touch the ground because they are so short. Bornean elephants are remnants of a domesticated herd from the 17th century. They were isolated about 300,000 years ago from other elephants in Asia and Sumatra; this caused them to evolve separately on the island of Borneo.

Bornean elephants are facing extinction due to deforestation and environmental destruction. Logging, agriculture, and palm oil plantations are to blame for this deforestation. Elephants are struggling to find enough food on the island of Borneo because only 40 percent of their habitat remains. Due to their size, these elephants require bigger areas to find food. The World Wildlife Fund has listed these elephants as endangered. Without addressing the deforestation problem, we are at risk of losing them forever. [read more]

How Mosquitos Choose Their Targets

by Dayanara Flores Gonzalez, age 14

Mosquitos can become immune to insect repellent over time. Mosquitos bite to harvest proteins from human blood. Research shows that mosquitos find different blood types more appetizing than others. Other studies show that it's controlled by the mosquito’s setting. Scientists discovered that 85 percent of people send a chemical signal through their skin which let mosquitos know which blood type each human has in their body.

Mosquitos locate their prey by smelling the acid, ammonia and other chemicals that are in people's sweat. Mosquitos are also attracted to people with higher body temperatures. For example, when you exercise and produce sweat this can allure mosquitos. Mosquitos also locate their targets by smelling carbon dioxide. They can detect this gas from as far as 164 feet away. People who exhale more gas over time show to attract mosquitos more than others. Different types of bacteria can affect how mosquitos react to the skin.

In a 2011 study, scientists found different types of large bacterias in human skin that attract mosquitos. However, a greater diversity of bacteria makes skin less attractive. [read more]

Fun Facts About Pine Martens

by Hiba Al-Quraishi, age 14

Pine martens are an animal species that inhabit Wisconsin, Alaska, Minnesota, Michigan, Canada, and the Rocky Mountains.

Pine martens are small and slender, weighing one to three pounds. They are approximately 15 to 24 inches long and six inches tall. Martens have big ears, a pointy face, large eyes, golden-brown fur, a yellow chest, and a long, thick tail. Females are about three-fourths the size of a male.

Pine martens are often seen in the northern parts of the state of Wisconsin and live deep in the woods. They can catch a lot of food because of their incredible climbing and fishing abilities. [read more]

Newly Discovered Sabre-Tooth Reveals Unknown Species

by Tierra Flowers, age 14

Scientists have found a new species of mammal—Diegoaelurus Vanvalkenburghae. It was a hypercarnivore which means that it exclusively ate meat. This saber-tooth tiger belonged to the animal family Machaeroidine as one of the first animals to have saber-like fangs. This sabertooth lived 42 million years ago in the tropical rainforest.

Only around a dozen of the fossils from the Machaeroidine were found. These fossils were seen in Wyoming and others were also found in Asia.

The lower jawbone of the sabertoothed animal was found in San Diego by a 12-year-old boy in the 1980s. By studying the structure of the lower jaw, scientists could identify and determine the shape and teeth of the animal. [read more]

Learn the Difference Between Mastodons and Mammoths

by Jeremiah Warren, age 12

Mammoths and mastodons were similar animals and today sometimes get confused with each other. Both animals had trunks and a tusk, similar to elephants today.

Until about 5,000 years ago, small populations of woolly mammoths lived on islands in the Arctic Ocean. Both mammoths and mastodons went extinct between 11,000 to 12,000 years ago.

When scientists find a skeleton, they look at the head to tell these animals apart. Mastodons had bigger heads than mammoths, while mammoths had a knob made out of bone on the top of their skulls. They both had long tusks, but mammoth tusks grew at a curve, with some even crossing in front of each other. Additionally, mastodons had much shorter and straighter tusks than mammoths. [read more]

Giant Jaguar or American Lion? Scientists Study a Species that Roamed Wisconsin During the Last Ice Age

by Jessica Lopez, age 13

The American Lion is an extinct big cat that populated North America about 11,000 years ago. This is around the same time that the humans who survived the Ice Age migrated to what is now known as Wisconsin. The American lion is also referred to as the American cave lion or the North American lion. It was one of the largest cats to exist on Earth.

The American lion has some similarities to other living species in the big cat family and with another extinct species, a type of European cave lion. For this reason, scientists have had difficulty pinpointing where this species exactly originated. Researchers have conducted various studies to try to determine the relatives of the American lion. It turns out that aside from being similar to many species of big cats, such as jaguars, the American lion seems akin to several species from Asia and Africa.

Another more recent study contradicts the hypothesis of the American lion being closely related to jaguars. Ancient samples of DNA were tested and now show that this lion was most directly related to the species of extinct European cave lions along with living African lions. [read more]

Orcas Learn to Hunt in Family Groups

by Tierra Flowers, age 13

On March 21, 2019, researchers in Western Australia were studying orcas, a species also known as killer whales. Suddenly, the scientists witnessed a phenomenon that no one had previously seen. They observed orcas killing the world’s largest animal, a blue whale.

On that day, this group of researchers from the Cetacean Research Center were traveling on a boat to their usual orca observation site. However, when they stopped to remove some trash from the water, they suddenly noticed some splashing in the distance. They observed the dorsal fins of several killer whales and saw that they were attacking a large whale species. That whale turned out to be a blue whale.

In this attack, 12 orcas were collaborating to take down a blue whale that was between 59-72 feet long. The whale’s entire body was covered in teeth marks. Its fins were bitten off, and its face was torn apart, showing exposed bone. Some of the orcas were slamming into the whale’s sides, while others were already feasting on different body parts.

A Deadly Hunter with a Fruity Name: The Lemon Shark

by Emily Bautista, age 13

The lemon shark is one of nearly 400 known species of sharks. Its length can be up to 10 feet and five inches, with its weight ranging between 265 to 330 pounds. The lemon shark's skin has a yellow tint, which gives the species its name. Its skin is covered in teeth-like scales known as denticles and it has the possibility to live at least 50 years.

Their usual diet is fish, including other sharks, rays, squid, and crustaceans. In fact, the lemon shark is a deadly hunter. The snouts of lemon sharks help them locate their prey by sensing electrical impulses. These sharks also have very sharp teeth that grow from the back to the front of their jaw. Their teeth are always growing to replace teeth that wear out or break.

Lemon sharks begin mating around the age of 12. Their gestation period, which is their pregnancy, usually lasts about 10 to 12 months. The breeding period for lemon sharks starts in early spring and summer. They give birth to about five to 19 pups. The lemon shark can be found on the coasts of North and South America, the Caribbean islands, and parts of the western coast of Africa. [read more]

“Extinct” Tortoise Discovered Alive on Remote Island

by Jessica Lopez, age 12

For nearly 100 years, scientists believed the Fernandina giant tortoise, native to the Galapagos Islands, had gone extinct. That changed when a recent expedition discovered evidence of this mysterious species on a remote island. Now, recent science is exploring how the tortoises’ population could make a comeback.

Washington Tapia, leader of the expedition, said, “For me it was the most important achievement of my life because I have been working on tortoise conservation for 30 years.” Tapia is the director of the nonprofit Galapagos Conservancy’s Giant Tortoise Restoration Initiative (GTRI) and has devoted her life to tortoise conservation.

Chelonoidis phantasticus, more commonly known as the Fernandina giant tortoise was found by Tapia and a group of four rangers from the Galapagos National park: Jeffreys Malaga, Eduardo Vilema, Roberto Ballesteros, Simon Villama. Also involved was biologist and Animal Planet host, Forrest Galante, who funded the trip. [read more]

Discover the Elegant Beauty of the Glasswing Butterfly

by Ayelen Flores Ruiz, age 11

Did you know there is a butterfly with see-through wings? If you haven't heard about it yet, then you are about to learn of the glasswing butterfly.

The glasswing butterfly is quite unique compared to other butterfly species. Typical butterflies have wings that are full of vibrant colors and patterns such as blue, orange, and yellow. However, the glasswing only has color on the tip of its wings.

The glasswing butterfly can be found in Latin American countries such as Mexico, Panama, and Colombia. Glasswing butterflies like to fly around rainforests. Fortunately, this species is able to fly in the rain. Their wings consist of scales that keep them from sticking together when they’re wet, giving the glasswing butterflies this special ability.

Big Cats Stalk the African Savannah

by Ayelen Flores Ruiz, age 11

Have you ever wondered what a lion's life is like? Lions spend much of their time hunting for food. These furry cats also live and raise their cubs in prides.

A male and a female lion look very different from each other. Male lions have sandy-colored fur that blends into their grassland habitat. They also have a mane of darker hair that makes them look powerful and dangerous. Female lions have sandy-colored fur too, but they do not have a mane.

The lionesses, or female lions, are responsible for hunting. They hunt as a team, which allows them to kill giant animals, such as zebras, wildebeests and buffalo. They usually hunt in the morning and evening. They do this so they can blend in with their surroundings, which makes it easier to sneak up on their prey. Most lions don't eat people, but they have done so in the past. [read more]

The One-of-a-Kind Cape Porcupine

by Destiny Flowers , age 13

Roaming around the boarder of the Kalahari Desert in the South of Africa lives the Cape Porcupine. In underground burrows, unless scavenging for food, it enjoys relief of the scorching hot sun and the protection of predators.

This Porcupine is a rodent, so its two front teeth are constantly growing. In order to keep its front teeth a reasonable size, it feeds on roots, bark, herbs and fruit. In order to find these foods, it uses its keen sense of smell. This porcupine needs water like any other living thing, so it gets it from a succulent plant.

A mother porcupine usually has one or two babies. Newborns are usually 12 ounces and are very energetic. Their quills are still soft and not fully developed. They stay in the burrow under their parents’ protection. The parents groom the young porcupines by licking them and escort them to feeding in a single-file line. The young stay suckling to six to eight weeks before they are able to find their own food. They are able to eat hard solid food at two or three weeks after birth. [read more]

Plants and Ants: Who Used Who First?

by Camila Cruz, age 11

Many ant species form symbiotic relationships with plants. Symbiotic means that both the plant and the ant benefit from being together.

These plants make nectar for ants to eat, and grow hollow thorns for the insects to live in. This proves beneficial to the plant, because ants eat the plant’s fruit and spit the seeds somewhere else so they can grow. So, the plants grow and the cycle continues. But, scientists are not sure how or when this relationship between plants and ants first began. [read more]

Beetles Aren't as Gross as They Look

by Jeaven Nevaeh Turner, age 13

What if an insect known to be disgusting to many people, could be some of the most helpful creatures to the world? That insect is a beetle; not just any beetle but a DUNG BEETLE, also referred to as the “clean up crew”.

Around the world, there are many different types of beetles: some may help people and some may not. Some beetles have fold up wings, horns and jaws. Some just have the love for consuming droppings from cows, buffalo, elephants, and other animals.

There are at least 300,000 species of beetles and every single one of those species are different and live in different parts of the world. [read more]

Watch Out For These Deadly Sea Creatures!

by Melanie Sanchez, age 11

When most people think of deadly sea creatures, they most often think about sharks. However, sharks rarely attack humans. There are other sea creatures that can kill people.

A blue-ringed octopus is usually smaller than a human hand. Although it seems quite harmless, one bite from this creature can kill. Even though its bite is painless, it can be fatal in just a few seconds. A human can become paralyzed and stop breathing.

Sea snakes are mostly found in the coral reef waters of the Pacific and Indian oceans. They hunt for their prey which hides in coral crevices or sandy burrows. One bite from these creatures can be as deadly as a cobra's bite. Most sea snakes will not attack humans unless they are provoked. The people who are most often killed by sea snakes are fishermen.

Butterflies and Moths: The Sky's Most Beautiful Creatures

by Zaniya Richardson, age 12

Butterflies and are some of the sky's most beautiful and colorful creatures, and although they might not seem all that special, they are. People are often surprised by the secrets these tiny insects hold.

During their earlier stages, butterflies and moths are caterpillars. Some caterpillars are poisonous, similar to how their older selves can be. Caterpillars build cocoons around themselves and then turn into butterflies and moths inside. This process is called metamorphosis.

Butterflies and moths do not have mouths to eat. Instead they have tubes. The tube is called a proboscis. These tubes are flexible allowing them to move to the blossom. The butterflies and moths extend their feeding tubes into the blossoms and extract the nectar. This is their food source. To these insects, blossoms are sweet and delicious, even though to humans nectar is bitter. [read more]
