Linophrynidae: Haplophryne mollis female anglerfish with males attached Antennariidae: striated frogfish, Antennarius striatus. Some anglerfish, like those of the Ceratiidae, or sea devils employ an unusual mating method. [34] Because individuals are locally rare, encounters are also very rare. Therefore, finding a mate is problematic.
Linophryne arborifera. Regan, 1925. Linophryne arborifera, or illuminated netdevil, [2] 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.
In most anglerfish the point of attachment for the male is on the belly, close to the anus, but in H. mollis the attachment site can be anywhere on the head or body, and in one case, a male attached to the female's esca (lure). The males orient themselves in random directions, and there may be more than one male per female.
Female triplewart seadevil, an anglerfish, with male attached near vent (arrow) Some species of anglerfish also display extreme sexual dimorphism. Females are more typical in appearance to other fish, whereas males are tiny rudimentary creatures with stunted digestive systems.
The male stays attached to the female for the rest of her life and fertilises her spawn many times. Some species may have more than one male sexual parasite, This strategy evolved to ensure that the spawn is fertilised in the sparsely populated habiata of these deepwater anglerfishes.
