It’s certainly not something you would want to come across swimming in the sea.
A rare, 13ft long Megamouth shark has been caught off the coast of Shizuoka in Japan, and has been providing a bit of excitement for locals.

The Marine Science Museum in Shizuoka held a public autopsy of the shark and 1,500 people reportedly turned up to have a look.
The grotesque shark reportedly survives on a diet of krill and shrimp and but scientists are keen to find out more about the creature.
It is only the 58th time ever that the shark has been spotted.
It comes just days after pictures emerged of a strange looking goblin shark, caught in the waters off Florida.
