The spawn of the anglerfish of the genus Lophius consists of a thin sheet of transparent gelatinous material 25 cm (10 in) wide and greater than 10 m (33 ft) long. [39] Such an egg sheet is rare among fish. The eggs in this sheet are in a single layer, each in its own cavity. The spawn is free in the sea.
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.
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.
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.
see text. Ceratioidei, the deep-sea anglerfishes or pelagic anglerfishes, is a suborder of marine ray-finned fishes, one of four suborders in the order Lophiiformes, the anglerfishes. These fishes are found in tropical and temperate seas throughout the world. One of the better known traits of the deep-sea anglerfishes is their extreme sexual ...
The specialised teeth on the denticular bones are used to temporarily attach the male to the female. [13] There is a record of a female with a scar on her skin that was probably caused by a male that became detached. [14] At the depths at which these fishes live it is dark and food is sparse and rarely encountered.
Günther, 1864. The humpback anglerfish (Melanocetus johnsonii) is a species of black seadevil in the family of Melanocetidae, which means "black whale" in Greek. [1] The species is named after James Yate Johnson, the English naturalist who discovered the first specimen in Madeira in 1863. [2] The common names include anglerfish, viperfish and ...
Smaller male size may be an adaptation to increase maneuverability and agility, allowing males to compete better with females for food and other resources. 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 ...
