UNDERWATER ANIMALS. A mating pair of deep-sea ANGLERFISH has been FILMED IN THE WILD FOR THE FIRST TIME. The species is a fanfin SEA DEVIL (Caulophryne jordani). The larger anglerfish is the female. Its long, flowing spines help it sense the prey that it lures in. When a tiny male finds a mate, it bites on, and stays – a parasite. Their tissues fuse. The male loses much of his body. He gets nutrients from the female’s blood, and will be at the ready for spawning. No one had ever seen a living pair. Kirsten and Joachim Jakobsen made the discovery while surveying diverse sea life of the Azores, a volcanic island chain of Portugal in the mid-Atlantic (from National Geographic official website).
