Cretalamna (SciiFii)

The dwarf megatooth shark (Cretalamna pygmiensis) is a species of otodontid shark that originally lived about 103 to 46 million years ago from the  Late Cretaceous to Eocene epochs as an extinct species of Cretalamna and was once extinct, but has since been brought back from extinction by SciiFii and introduced to the modern oceans worldwide to help boost biodiversity. The original species of Cretalamna is considered by many to be the ancestor of the largest sharks to have ever lived, Carcharocles angustidens, and Carcharocles megalodon. The pygmy megatooth shark is a medium-sized shark with a total length of 2.3 – 3 meters. It has a fusiform-like body plan comparable to those of native modern lamniforme sharks. Given the size of the pygmy megatooth shark's teeth relative to its body size, its caudal fin is not used for stunning prey (as is the case for thresher sharks). Instead, the caudal fin of the pygmy megatooth shark is more similar to that of the great white shark. The pygmy megatooth shark is a generalist predator and scavenger, preying mainly on large bony fish, turtles, mosasaurs, pinnipeds medium-sized whales, squids, and other sharks. The conservation status of the pygmy megatooth shark is Least Concern due to successful conservation efforts, the pygmy megatooth shark's wide range, and its tolerance to most of human activities. It is also completely tame, docile, peaceful, and gentle towards people, so the people seem to tolerate the pygmy megatooth shark's presence even in public beaches.
