Viper Fish
A viperfish is any species of marine fish in the genus ''Chauliodus''. Viperfishes are mostly found in the mesopelagic zone and are characterized by long, needle-like teeth and hinged lower jaws. A typical viperfish grows to lengths of . Viperfishes undergo diel vertical migration and are found all around the world in tropical and temperate oceans. Viperfishes possess photophores along the ventral side of their body, likely used to camouflage them by blending in with the less than 1% of light that reaches to below 200 meters depth. Although it may appear to be covered in scales, viperfishes do not possess scales. Rather, they are covered by a thick, transparent coating of unknown substance. Extremely large, fang-like teeth give the fish a slightly protruded lower jaw. Habitat Viperfishes live in meso- and bathypelagic environments where humans cannot easily make direct observations. Viperfishes engage in diel vertical migration, meaning they migrate up into more productive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Weever
The lesser weever (''Echiichthys vipera'') is a venomous weever of the family Trachinidae, in the order Perciformes, and the class Actinopterygii. It is generally found on the sandy sea beds of the open sea, near the shore. Lesser weevers may sting swimmers badly if disturbed in the water, and fishermen when they clean their fishing nets. The lesser weever grows up to 18 cm long, but generally less than 15 cm, with an elongated body. Its color can be described as greyish-brown on the back and silvery-white on the sides. It has no spines in front of its eyes. Habitat Lesser weever fish occur in the eastern Atlantic from the North Sea around the British Isles to Morocco and Madeira, and in the Mediterranean. It is typically found resting on the bottom, partially buried with its eyes and tip of the first dorsal fin exposed. Biology The lesser weever is littoral and benthic, living on sandy, muddy bottoms, ranging from a few meters deep to 150 m (in winter). Resting ...

Samuel Garman
Samuel Walton Garman (June 5, 1843 – September 30, 1927), or "Garmann" as he sometimes styled himself, was a naturalist/zoologist from Pennsylvania. He became noted as an ichthyologist and herpetologist. Biography Garman was born in Indiana County, Pennsylvania, on 5 June 1843. In 1868 he joined an expedition to the American West with John Wesley Powell. He graduated from the Illinois State Normal University in 1870, and for the following year was principal of the Mississippi State Normal School.

Chauliodus Sloani
Sloane's viperfish, ''Chauliodus sloani'', is a predatory mesopelagic dragonfish found in waters across the world. The species was first described by German scientists Marcus Elieser Bloch and Johann Gottlob Schneider in their 1801 book ''Systema ichthyologiae: iconibus CX illustratum'', volume 1.Bloch, M. E., & Schneider, J. G. (1801). ''Systema ichthyologiae: iconibus CX illustratum'' (Vol. 1). Auctor. Female ''C. sloani'' reach maturity between 133 and 191 mm, while males likely reach maturity at slightly smaller body lengths. It has two rows of photophores along its ventral side.Whitehead, P. J.

It is believed that ''C. sloani'' can adjust the intensity of bioluminescence of the ventral photophores to camouflage itself from predators that might see its shadow from below. T ...
