Rays are interesting creatures that have been around for 150 million years. They are calm animals but when you disturb them, they can attack using their venomous spines or barbs on their tails. There are various types of rays including stingrays, manta rays, butterfly rays, and electric rays.
Manta Rays are very large animals and can reach widths of up to seven meters. These creatures migrate across the oceans in groups as large as 10,000 individuals.
Stingrays are another unique type of ray. The stingray has jelly-filled canals on its face that give it an electromagnetic sense, called the ampullae of Lorenzini. This sense helps it search for food and detect other animals' electrical signals. Their diet consists of fish, snails, and other small crustaceans. There are many species of rays, about 539, and many of them are considered threatened.
Some more rays include the round butterfly ray and the short-nosed electric ray, which is considered the smallest ray, measuring ten centimeters. Electric rays can create electric currents to stun prey or defend themselves from predators.
Stingrays can be found in oceans all around the world, however, their habitats are being destroyed constantly. A combination of people overfishing and climate change is making it difficult for them to survive.
