The mantis shrimp is believed to have the most complex eyesight of any animal, including humans. This marine animal has a much wider visual spectrum than any other animal, with an ability to see colors that humans can't see.

Dugongs are also known as seacows. They are large mammals with front flippers and tails, which they use as propellers. They live in the seas around Australia.
