Seals
- Seals are warm-blooded, air breathing mammals
that live in or near the sea.
- There are around 33 species of seals.
-They have four flippers, so are in a category of animals known as pinnipedia which means 'fin-footed'.
- A seal's whiskers help it to detect prey in dark murky waters.
- Because they can spend months at sea, seals can sleep underwater
- Some seal species can hold their breath for nearly two hours underwater by slowing their heart beat and conserving oxygen.
- Humans have traditionally hunted seals for their meat, blubber and fur coats, however seals are now protected by international law. They are still commonly kept in captivity though and sometimes trained to perform tricks and tasks.
