Linophryne, the bearded seadevils, is a genus of marine ray-finned fishes belonging to the family Linophrynidae, the leftvents. These deep sea anglerfishes are found in the Atlantic, Indian and Pacific Oceans.

Taxonomy

Linophryne was first proposed as a monospecific genus in 1886 by the Norwegian zoologist Robert Collett when he described L. lucifer as a new species. [3] Collett gave the type locality of L. lucifer as off Madeira at around 36°N, 20°W. [4] The 5th edition of Fishes of the World classifies this genus within the family Linophrynidae, which it places within the suborder Ceratioidei, the deep sea anglerfishes, within the order Lophiiformes, the anglerfishes. [5]

Etymology

Linophryne prefixes linos, which means "net", an allusion Collett did not explain when he proposed the genus, with phryne, meaning "toad". The prefix may be a reference to the sac like mouth hanging off the trunk, which in the holotype contained a lanternfish, like a fisherman's keep net. The second part phryne is commonly used in the names of anglerfish genera. Its use may date as far back as Aristotle and Cicero, who referred to anglerfishes as "fishing-frogs" and "sea-frogs," respectively, possibly because of their resemblance to frogs and toads. [6]

Species

Linophryne contains 22 recognised species, these are divided into 3 subgenera: [7]

Characteristics

Linophryne leftvents are sexually dimorphic and the metamorphosed females can be distinguished from the other leftvent genera by a number of characters. These include the possession of a hyoid barbel, well-developed spines on the sphenotic bone and the preoperculum and a single nearly oval bulb on the esca with a short projection in its middle and has no appendages as well as a low number of fin rays in the dorsal and anal fins. [8] The largest species in the genus is L. lucifer which has a maximum published standard length of 27.5 cm (10.8 in). [7]

Distribution and habitat

Linophryne is found circumglobally in all three Oceans [7] from as far north as Iceland and Greenland in the Atlantic Ocean [9] they are found at depths between 0 and 2,200 m (0 and 7,218 ft). [10] [11]

Fossil record

Linophryne is represented in the fossil record by what may be L. indica was found in Late Miocene strate of Los Angeles, California, along with a fossil of the related Borophryne apogon , during the construction of a metrorail. [1]

<i>Lasiognathus</i> Genus of fishes

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.

<span class="mw-page-title-main">Anglerfish</span> Bony fish of the teleost order Lophiiformes

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.
