angler fish

The anglerfish are fish of the teleost order Lophiiformes (/ˌlɒfiɪˈfɔːrmiːz/).[1] They are bony fish named for their characteristic mode of predation, in which a modified luminescent fin ray (the esca or illicium) acts as a lure for other fish. The luminescence comes from symbiotic bacteria, which are thought to be acquired from seawater,[2][3] that dwell in and around the sea.

Some anglerfish are notable for extreme sexual dimorphism and sexual symbiosis of the small male with the much larger female, seen in the suborder Ceratioidei, the deep sea anglerfish. In these species, males may be several orders of magnitude smaller than females.[4]

Anglerfish occur worldwide. Some are pelagic (dwelling away from the sea floor), while others are benthic (dwelling close to the sea floor). Some live in the deep sea (such as the Ceratiidae), while others live on the continental shelf, such as the frogfishes and the Lophiidae (monkfish or goosefish). Pelagic forms are most often laterally compressed, whereas the benthic forms are often extremely dorsoventrally compressed (depressed), often with large upward-pointing mouths.[citation needed]

Evolution[edit]

The earliest fossils of anglerfish are from the Eocene Monte Bolca formation of Italy, and these already show significant diversification into the modern families that make up the order.[5] Given this, and their close relationship to the Tetraodontiformes, which are known from Cretaceous fossils, they likely originated during the Cretaceous.[6][7] A 2010 mitochondrial genome phylogenetic study suggested the anglerfishes diversified in a short period of the early to mid-Cretaceous, between 130 and 100 million years ago.[8] A more recent preprint reduces this time to the Late Cretaceous, between 92 to 61 million years ago.[7] Other studies indicate that anglerfish only originated shortly after the Cretaceous-Paleogene extinction event as part of a massive adaptive radiation of percomorphs, although this clashes with the extensive diversity already known from the group by the Eocene.[7][9]

Classification[edit]

FishBase,[1] Nelson,[10] and Pietsch[11] list 18 families, but ITIS[12] lists only 16. The following taxa have been arranged to show their evolutionary relationships.[4]

‘Ultra-rare Deep-sea Footballfish’ Washes Ashore California Beach

Scientifically known as Himantolophidae, footballfish is mostly found in Atlantic, Indian, and Pacific Oceans Photograph:(Agencies)

STORY HIGHLIGHTS: Scientifically known as Himantolophidae, footballfish live in waters that are 3,000-4,000 feet deep. The creature is mostly found in tropical and subtropical waters of the Atlantic, Indian, and Pacific Oceans.

Pictures of an ultra-rare deep-sea fish dubbed “deep-sea monster” has gone viral after a tourist spotted the creature washed ashore at a beach in California, USA. On November 13, Jay Beiler was walking on Black’s Beach in Torrey Pines in San Diego when he spotted the “ultra-rare” species.
