#19 – Frilled Shark
It almost resembles an eel, but it can also pass off as a sea serpent – if you believe in that kind of stuff.
Unlike most sharks with jaws that are positioned further back on the head, the jaws on the frilled shark extend to the end of the snout. It has about 300 teeth in total spread across the upper and lower jaws. The “frills” from its name come from its gills – there’s 6 pairs of long gill slits located around its neck, giving the shark its “frilly” appearance.
The largest known length of this creature is 6.6 feet (2.0 meters) for females and 5.6 feet (1.7 meters) for males.
