Linophryne arborifera
''Linophryne arborifera'', or illuminated netdevil,〔Tim Flannery and Peter Schouten, ''Astonishing Animals: Extraordinary Creatures and the Fantastic Worlds They Inhabit''. New York: Atlantic Monthly Press, 2004. Page 192.〕 is an anglerfish of the family Linophrynidae, found in all tropical and subtropical oceans at depths below 1,000 m (3,300 ft) in the Bathyal zone. Its length is up to 77 mm (3 inches). The female is significantly larger than the mature, parasitic male.
==Characteristics==
The literal translation is ''Linophryne arborifera'', which is Greek for “tree-bearing flax-toad.” The female ''Linophryne'' has not only a luminous lure on the head, called the esca (Latin for “food”), but also a multibranched barbel hanging from the lower jaw. The barbel filaments contain many more bioluminescent organs.
At a length of up to 77 mm (3 inches), females are significantly larger than the males, which reach only about 15 mm (0.6 inches).〔Pietsch, TW, Dimorphism, parasitism, and sex revisited: modes of reproduction among deep-sea ceratioid anglerfishes (Teleostei: Lophiiformes), Ichthyol Res (2005) 52: 207–236〕 After metamorphosis they are black in color. They have no scales and gelatinous skin. They are different from all other ceratioid families in having dorsal-fin rays 3 (rarely 4), anal-fin rays 3 (rarely 2 or 4), branchiostegal rays 5 (rarely 4), and a sinistral (opens to the left) anus. The eyes of linophrynid males are very well developed and unique among ceratioids in being tubular and directed somewhat forward. The nostrils of linophrynid males are also large and well developed.
