Dolphins, despite their size and status as a mammal, can dive up to 1000 feet!

Dolphins can swim at speeds of up to 19 mph

Dolphins are considered to be evolved from a four legged mammals, because they still breathe air

Manatees are one of the best Animals ever. When sailors came over from Europe, they thought the sea cows (as they're called) were Mermaids....yeah...:P

The Medusa jellyfish, one of the most common Jelly's, is made up of only 5% solid matter

Corals are composed of polyps that make up many different shapes

Orcas, a.k.a. "Killer Whales," often travel in "pods" or family groups
