Cryptoclidus (SciiFii)

Cryptoclidus marinus is a species of plesiosaur reptile that originally lived from the Middle Jurassic period of England, France, and Cuba as an extinct species of Cryptoclidus and was once extinct, but has since been brought back from extinction by SciiFii and, unlike most Mesozoic marine reptiles, have been introduced throughout the world's oceans to help boost biodiversity. Cryptoclidus marinus is a medium-sized species, growing up to about 5 metres (16 feet) long and weigh 5 tons. Due to its head being weak and its teeth preclude any grappling with prey, so it feeds on small, soft-bodied animals such as squid and shoaling fish. It uses its long, intermeshing teeth to strain small prey from the water, as well as to sift through sediment for buried animals. It is a social animal that lives in pods of up to around 20 individuals at a time, and, unlike native modern non-avian reptiles, it is warm-blooded animal so it is very active. To keep itself warm in cool oceans, it has blubber in its body to protect itself against the cold temperatures. The conservation status of Cryptoclidus marinus is Least Concern due to successful conservation efforts, the animal's wide range and its tolerance to most of human activities.
