Goblin Sharks Use Jelly Filled ElectroReceptors To Sense Faint Electric Fields Produced By Nearby Prey

The goblin shark is a rare species of sharks that live deep below the sea. The shark has a very unique look with a pink colored skin and dangerously sharp teeth. The sharks are typically about three to four meters in length but can grow much larger as mature adults. Goblin sharks can be found in a few different environments such as submarine canyons, seamounts and continental slopes. They will usually be at depths of greater than three hundred thirty feet.

Something very interesting about the goblin shark is that its long snout is covered with a special sensing organ known as a ampullae of Lorenzini also called electroreceptors. These receptors form a network of jelly filled pores and allow the shark to sense very faint electric fields that are produced by nearby prey, which the fish then snatches up by rapidly extending its jaws. These fish are occasionally caused by deepwater fisheries, but this is a rare occasion and is typically unintentional.

Back in the year two thousand, a fisherman captured a gigantic female goblin shark that was approximately 18 to 20 feet in length. The maximum weight that has been recorded for this shark is four hundred sixty pounds at three point eight meters in length.

Even though this animal may look a bit scary, it poses completely no danger to humans, unless you happen to stumble into a public aquarium where a few specimens might exist. Most of these sharks that are taken into captivity after being caught in deep waters have not survived for very long. One of these goblin sharks was kept at the Tokai University in Tokyo, Japan, but it only lived for a week. Another one at the Tokyo Sea life Park lived for two short days. Unfortunately for the goblin shark, the jaws batch high prices from collectors, but this hasn’t done much to boost a nonexistent market because of the difficulties of catching a goblin shark that spends most of its time hundreds of feet below the ocean waters.
