Frilled Shark, which was formerly known as a pre-historic animal. Despite the fact that it belongs to a primitive species, the frilled shark hasn't really evolved much over the years. The fact that it has 300 trident-shaped teeth set in 25 rows, makes it a very scary animal to encounter. It also takes about three and a half years to give birth, which breaks the record for gestation period among sharks- as presumed by scientists.
