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. [1]

Taxonomy

Ceratioidei was first proposed as a grouping in 1912 by the English ichthyologist Charles Tate Regan as the division Ceratiformes within the suborder Lophoidea of the order Pediculati, which included the Batrachoididae. [2] The Batrachoididae are not now cosidered to be closely related to the anglerfishes which are now included in the order Lophiiformes. Ceratioidei are in the same clade as the Chaunacoidei with the Antennarioidei and the Ogcocephaloidei as the sisters of that clade. [3] The 5th edition of Fishes of the World treats this grouping as a suborder within the Lophiiformes. [4]

Evolution

A 2024 study found that although the ceratioids likely diverged from the Chaunacidae during the Paleocene, the diversification into their multiple modern families only occurred throughout the Eocene following the Paleocene-Eocene Thermal Maximum. This likely also coincides with their colonization of deep-sea habitats. Prior to these radiations, ancestral ceratioids lost adaptive immune genes such as aicda , which may have led to the extreme sexual size dimorphism seen in later ceratioids, and ultimately the evolution of their sexual parasitism. [5]

Etymology

Ceratioidei takes its name from the genus Ceratias , the type genus of the family Ceratidae and of the suborder. Ceratias means "horn bearer", an allusion to the esca sticking up from the snout. [6]

They are mostly found at depths between 200 and 3,000 m, but have been recorded as deep as 4,000 m (13,000 ft). A few species live in much shallower coastal waters and, exceptionally, may enter river estuaries.

<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.

The complete anglerfish (Lasiognathus) is a genus of deep-sea anglerfish in the family Thaumatichthyidae, with six species known from the Atlantic and Pacific Oceans. Its lure apparatus appears to consist of a fishing rod, a fishing line, bait, and hooks. It is also distinctive for an enormous upper jaw with premaxillaries that can be folded down to enclose the much shorter lower jaw.

The anglerfish are fish of the teleost order Lophiiformes. They are bony fish named for their characteristic mode of predation, in which a modified luminescent fin ray acts as a lure for other fish. The luminescence comes from symbiotic bacteria, which are thought to be acquired from seawater, that dwell in and around the sea.
