The elusive deep-sea shark "goblin shark," filmed swimming alive for the first time in the world

Explanation

The goblin shark, a deep-sea shark also called a "living fossil," has been filmed swimming in its natural habitat for the first time in the world. A team from the University of Hawaii and others recorded a total of two individuals on a seamount near Jarvis Island and on the slope of the Tonga Trench. All previous observations had been limited to individuals caught in fishing nets, and almost nothing was known about their ecology in a healthy state. This discovery also revealed that their habitat range is much wider than previously thought.
