Some whales eat mammals, squid, krill, and so forth.
I love dolphins and I know now that I want to continue researching them after I go to college. My love for animals led to a job working for a vet, which led to a job working for a local zoo, and then on to college, and then I became a zoo keeper, curator, and zoo director. Sharks have lots of teeth - rows and rows. And, also check into programs at your local zoo for different age groups. But, a tiger's main means of hunting is by leaping.
