Slow-moving killer

The Greenland shark is one of the slowest-moving fish ever recorded and has been found with reindeer, polar bears, and fast-moving seals in its stomach. It's thought that Greenland sharks prey upon sleeping seals, which snooze in the water to avoid polar bears.

Megamouth!

One of the rarest sharks is the megamouth shark (Megachasma pelagios, meaning "giant mouth of the deep"). Fewer than 100 specimens of the beast have ever been seen. It was first discovered in in 1976 when struck by and tangled in the anchor of a Navy ship off Hawaii. The animal can grow up to 15 feet (4.6 meters) long and is a filter feeder, syphoning plankton from the water.

Did you know some sharks can reproduce without having to mate first?

Some captive female sharks have been known to reproduce without the aid of a male, essentially cloning themselves. In 2001, a female hammerhead shark gave birth in the Henry Doorly Zoo in Nebraska without mating with a male, taking researchers by surprise. It's an example of parthenogenesis, wherein embryos can be created without external fertilisation, and has been seen in all types of animals except for mammals.

It's not sharks, but it's still totally gross and freaky

It's not sharks, but it's still totally awesome.
