Thaumatichthyidae, the wolftrap anglers, is a small family of marine ray-finned fishes, also called the wolftrap seadevils, classified within the suborder Ceratioidei, the deep-sea anglerfishes. They have distinctive upper jaws with movable premaxillaries that can be lowered to form a cage-like trap around the much shorter lower jaw.

Taxonomy

Thaumathichthyidae was first proposed as a monotypic family in 1912 by the American ichthyologists Hugh McCormick Smith and Lewis Radcliffe, [1] with Thaumatichthys as its only genus. [2] The 5th edition of Fishes of the World classifies this family in the suborder Ceratioidei of the anglerfish order Lophiiformes. [3] Within the Ceratioidei this family is a sister taxon to the Oneirodidae. [4]

Etymology

Thaumatichthyidae is derived from its type genus, Thaumatochthys. This name is a combination of "thauma", meaning "wonder" or "marvel", and ichthys, the Greek word for "fish". The name alludes to the strange shape of T. pagidostomus with its large head that is almost as long as the rest of the body, the esca and illicium being inside the mouth to lure the prey into the huge trap-like mouth. [5]

Genera

Thaumatichthydae has the following two genera classified within it: [6]

Characteristics

Thaumatichthyidae anglerfishes resemble their close relatives the dreamers of the family Oneirodidae. The main differences are that the lower jaw projects well beyond the upper jaw and the upper part of the operculum is bifurcated. In comparison to other Ceratioid anglerfishes the wolftrap anglerfishes do not have the front end of the jawbones join at the midline of the mouth, where there is a wide elastic membrane. They have very long, inwardly hooked premaxillary teeth. They also have tooth-like denticles on the esca. The pectoral fin has between 14 and 20 soft rays while the caudal fin has 9 soft rays, the 3 middle rays being forked. The maximum published standard length is 36.5 cm (14.4 in) for Thaumatichthys axeli , while the smallest is 7.7 cm (3.0 in) in the case of Lasiognathus saccostoma . Larvae have been recorded at 2.25 cm (0.89 in) while the largest free-living males are 3.6 cm (1.4 in). [7]

Distribution and habitat

Thaumatichthyidae anglerfishes are found at depths down to 4,000 m (13,000 ft) in the Atlantic and Pacific Oceans. [7]

<i>Thaumatichthys</i> Genus of fishes

The Wonderfish (Thaumatichthys) is a genus of deep-sea anglerfish in the family Thaumatichthyidae, with three known species. Its scientific name means "wonder-fish" in Greek; oceanographer Anton Bruun described these fishes as "altogether one of the oddest creatures in the teeming variety of the fish world." In contrast to other anglerfishes, the bioluminescent lure of Thaumatichthys is located inside its cavernous mouth. They are worldwide in distribution and are ambush predators living near the ocean floor.

It is also distinctive for an enormous upper jaw with premaxillaries that can be folded down to enclose the much shorter lower jaw.

<span class="mw-page-title-main">Ceratioidei</span> Suborder of fishes

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 dimorphism where the males are many times smaller than the females, the males seek out females and use their sharp teeth to clamp onto the females where he remains for the rest of his life, in some species he becomes part of the female. This is the only known natural example of a process called parabiosis. Another common trait of deep-sea anglerfishes is that they use bioluminescence on their esca to attract prey in the darkness of the deep oceans they inhabit.

Chaenophryne melanorhabdus is a species marine ray-finned fish belonging to the family Oneirodidae, the dreamers, a family of deep sea anglerfishes.
