This creature is a living fossil, meaning it has gone through little change since the time of the dinosaurs. Resembling something from a sci-fi comic, the Vampire Squid surprisingly only reaches lengths of 6 inches to one foot. This animal resides half a mile deep in the ocean and uses its unique blue eyes to see. Using two large fins near its head, the vampire quid is able to propel itself through water quite quickly.
Hey, just realized that this was supposed to be more rare sea creatures, not the more common ones. The rybynazywo largest crocodile ever caught alive was a male estuarine crocodile named Lolong, measuring 20 feet and 3 inches and weighing 2370 pounds. He was caught September 2011 in the province of Agusan del Sur, Philippines, having been accused of eating humans and water buffalo. Until he died in February 2013, he was the world’s largest crocodile in captivity.

Turtles are cold-blooded Testudines and inhabit both freshwater and seawater habitats. Sea turtles are almost entirely aquatic and possess flippers instead of feet, which they use to generate thrust. Unlike the male sea turtles which never leave the sea, the female species must come on land to lay eggs. Their movement on land is very limited and often slow and laborious. There are seven species of sea turtles, namely flatback turtle, green turtle, hawksbill turtle, Kemp’s ridley turtle, leatherback turtle, and loggerhead turtle. All seven species face extinction due to habitat degradation and bycatch among other threats.
