=Fish or Mammals?= Although dolphins, porpoises and whales live in the ocean and are shaped like fish, they are not fish. They are aquatic mammals, like seals. However, unlike seals, they belong to a different group and the posh name for it is cetaceans. Cetaceans have high intelligence level than other animals and their brains are bigger than humans'. However, it DOES NOT mean that cetaceans are smarter than humans. I love dolphins but I have to admit that. Have you ever seen a dolphin winning the Nobel Prize? =Sleeping and Snoring= Sleeping is tough for cetaceans. When we want to sleep, we just lie down and close our eyes(and snore). However, for cetaceans, they have to keep a half of their brain awake, as they cannot do without being in water and they must breathe air. They also probably have to watch out for hungry sharks! In addition, cetaceans don't snore like some humans. Heehee.
