There’s a reason the Goblin Shark looks like a beast from prehistoric times. This rare species comes from the Mitsukurinidae family which dates back over 125-million years. Known to shark-lovers as the Living Fossil, the Goblin Shark isn’t much of a looker – then again, when your habitat is somewhere between 890 and 3,150 feet deep in the ocean, looks don’t really matter.

As well as its distinctive snout, this shark has a scary number of teeth. Its upper jaw has somewhere between 35 and 53 rows of teeth, while the lower jaw has 31 to 62 rows. However, since the shark is not a fast swimmer and has poor eyesight, it relies solely on its natural buoyancy to silently ambush its prey.
