There are 33 species of pinnipeds alive today, most of which are known
as seals. Pinnipeds can be found on every continent on Earth, though
most species occur in cold-water environments. Thick layers of fat, also
known as blubber, keep the animals warm, in addition to dense fur. Seals
range greatly in size, from the gargantuan southern elephant seal, which
can weigh more than a pickup truck, to the relatively slender, 100-pound
Baikal seal. All seals eat other animals, and most rely on fish caught
out at sea. But a few species break the mold. For instance, leopard
seals make a living hunting down penguins and even other seals.
Evolutionarily speaking, seals are thought to be most closely related to
bears and the group of animals that includes weasels and otters, as well
as skunks, raccoons, and red pandas.
