Swimming Creatures - Lesson 3 Seals and Sea Cows
In this lesson, we learned all about pinnipeds (seals, sea lions, & walruses), what a true seal is and how to tell the difference between a true seal (cannot use rear flippers on land, small front flipper ending in claws, and no ear flaps) and a sea lion or fur seal (can use rear flippers on land, long hairless front flipper, and has ear flaps).
