Goblin Shark

Goblin Shark: one of the coolest and most frightening sharks in all of the ocean. It can extend its jaw out and then snap it right back in in approximately one second. As you can tell, you probably don't want to get in a fight with a Goblin Shark but very recently a scuba diver got in a fight with a Goblin shark, but fortunately, because it was a juvenile its jaws could barely penetrate the wet suit. Had it been a 16 foot long adult, it could have done some serious damage.
