Fast and Deadly Predators in the Ocean


Orcas are really incredible mammals that swim – fast and deadly – all over the world.

Male and female orcas have different dorsal fins. Male orcas have long straight fins and female orcas have short, curved ones. Their teeth, which are shaped like cones, help them bite into the flesh of their prey. Their tails help them swim at a speed of 31 miles per hour. They weigh over 13,230 pounds.

Orcas mate between December and June in the Southern Hemisphere and between May and July in the Northern Hemisphere. They only have one baby every two to six years.

Orcas live in oceans all over the world but prefer cooler waters. The orcas’ diet consists of fish, squid, seals, sea lions, and other whales, including the minke whale. The orcas even will hunt other whales! They do this by traveling with speed, by being the largest, and also by working together with other orcas.

Orcas are awesome mammals to learn about because there is a lot to know about them.
