 Seals do not dive deep or stay under water long. The
maximum is only a couple minutes. However some seals while hunting,
can stay under water for as long as thirty minutes and dive as
deep as 1,000 feet (305 meters.) They are able to do this without
running out of oxygen because scientists believe they have more
blood in their body than land animals do which gives them enough
oxygen to do this. They swim, breed, and pupp in large groups
for protection. Seal's legs were adapted into flippers so they
could swim and catch food easier. |
