Goblin shark

Goblin shark Introduction

The Goblin shark is a weird, wild, and interesting creature that dwells deep in the depths of the world’s darkest oceans. Named for the goblin or “Tengu” in Japanese folklore, the Goblin shark certainly lives up to its name—at least in terms of its appearance. The Goblin shark is known as a “living fossil” which is a term for any animal that is unique in the present-day ecosystem but closely resembles species that lived millions of years ago. Because it makes its home in dark and remote areas of the deep ocean, the Goblin shark is difficult to study. This means that little is known about its habits or lifestyle in the wild. However, by analysing goblin sharks that have been caught by fishermen and scientists, it is possible to make educated guesses about the nature of this mysterious and frightening beast. The most striking feature of the Goblin shark is its pronounced, flattened snout. This snout is actually covered with electroreceptors that allow the Goblin shark to sense its prey, mainly smaller fish, by the minute electric fields they produce. Some have speculated that this long snout could be used to stir up sediment on the ocean floor to uncover food, but due to its soft and flabby nature this is likely not the case. Underneath the snout, the Goblin shark has a hinged and fully mobile jaw lined with needle-like teeth. This jaw can extend nearly to the front of the snout, and the goblin shark uses it to spring a trap for its prey. The body of the Goblin shark is flabby and soft with underdeveloped muscles, which gives scientists clues into the shark’s behaviour—causing them to assume that Goblin sharks are slow-swimming. The skin is soft and semi-transparent, typical of many deep-sea fish, but the colour of the Goblin shark’s skin does change as it ages, going from nearly white to a dark grey. Because of its supposedly slow nature, the Goblin shark likely ambushes its prey, and the mobile jaw could be a direct adaptation to this slow-swimming lifestyle. Despite its rarity, the Goblin shark is listed as “least concern” because it rarely faces any human threats due to its remote environment.
