*Anoplogaster cornuta* (Valenciennes, 1833)

Anoplogaster cornuta , the common fangtooth, is a species of deep sea fish found in temperate and tropical oceans worldwide. It is constitute at depths of from 2 to 5,000 metres (10 to 16,400 ft) with the adults usually institute from 500 to v,000 metres (1,640 to sixteen,400 ft) and the young commonly found nigh the surface. This species grows to a total length of nearly 18 cm (seven in). While a source of nutrient for pelagic carnivorous fishes, this species is of no interest for homo fisheries.

Clarification [edit]

The mutual fangtooth has a distinctive appearance and grows to a total length of about 18 cm (vii in). Adults are dark brown to black, the head is very big, bony and finely sculptured merely does not comport any spines. The eye is small and the gill rakers have bony bases and are molar-like. The body is deepest just backside the head, tapering apace to the caudal peduncle. The mouth is well-armed with sharp fangs and the skin is granular. The dorsal fin has no spines and 17 to twenty soft rays while the anal fin has no spines and vii to nine soft rays. The lateral line takes the form of an open groove, bridged in places by overlapping scales. Many deep sea fish practise not have swim bladders, but the common fangtooth does.^[ii] ^[3]

Juveniles look very different from adults, then much and so that they were at one time believed to exist a different species.^[2] The juveniles were first described as Anoplogaster cornuta by the French zoologist Achille Valenciennes in 1833, and information technology was fifty years after that the adults were described and given the name Caulolepis longidens. Not until 1955 was information technology appreciated that the two were the aforementioned species. The juveniles are a much paler colour and somewhat triangular in cross section. They have several long spines on the head, large optics and slender, pointed gill rakers, merely have modest teeth and lack the fangs of the adult fish.^[2] ^[3] The peel is largely unpigmented and clad in unpigmented scales, but in that location is a black patch on the belly formed past dark-coloured cup-like scales. As the juvenile reaches adulthood, it becomes darker as black scales grow to cover its still-unpigmented skin.^[4]

Distribution and habitat [edit]

The common fangtooth has a global distribution being found in tropical and temperate waters in both the eastern and western Atlantic Ocean, the Indian Ocean and the Pacific Ocean. Off the western seaboard of America its range extends from British Columbia southwards to south of the equator. Information technology is a pelagic fish occurring betwixt 2 and 5,000 metres (10 and 16,400 ft), with adults between 500 to v,000 metres (1,640 to xvi,400 ft); adults occur in deep water and are oft caught in trawls at near 2,000 m (half dozen,560 ft). Juveniles are plant at bottom depths.^[2]

Behaviour [edit]

The common fangtooth is a predator and feeds on other fish, crustaceans and cephalopods. They are themselves preyed on by such fish as tuna, marlin and albacore. It is a schooling fish and is often establish in minor groups, though it may be alone. Off the westward coast of North America, the mutual fangtooth seems to breed in the summer months. The fish are oviparous and the developing larvae are planktonic.^[3] From exam of the otoliths (bony structures backside the eyes), information technology appears that this fish lives for at to the lowest degree 3 years.^[two]

Inquiry [edit]

These fish were tested to see how pressure level effects their respiration as compared to other fish. Researchers found that these fish are able to regulate their respiration system according to their surround and that the respiration rate was directly proportional to the size of the fish.^[5]

Although almost no light penetrates to the deep body of water from the surface, the common fangtooth has evolved features that get in practically invisible. Like other deep bounding main fish, it needs to avert beingness seen by predators, some of which hunt for prey by creating their ain light by ways of bioluminescence. The common fangtooth achieves invisibility by absorbing light with not bad efficiency. The paint melanin is crammed into granules which are grouped into melanophores which cover virtually the whole of the dermis. This absorbs almost all of the incoming light, and whatsoever remaining light that scatters sideways is captivated past neighbouring granules. Altogether, the absorption of low-cal is 99.5% efficient, a fact that makes photographing this fish in its natural habitat very difficult.^[6]
