Genus species (Animalia): Holocentrus adscensionis

Holocentrus adscensionis is a squirrelfish of the family Holocentridae found in the Atlantic Ocean. Its range extends from North Carolina, USA to Brazil and throughout the Caribbean Sea in the Western Atlantic and from Gabon to Ascension Island in the Eastern Atlantic. It generally stays between 8 and 30 meters (26 and 98 ft) below the surface, but can be found at the surface or as deep as 180 meters (590 ft). It can reach up to 61 centimeters (24 in) in length, although it is more common for individuals to be around 25.0 centimeters (9.8 in).

Being largely or entirely nocturnal, they have relatively large eyes. During the day, they typically remain hidden in crevices, caves, or under ledges. The preopercle spines (near the gill opening) of the members of the subfamily Holocentrinae are venomous, and can give painful wounds.

The Beryciformes order

The Beryciformes are a poorly-understood order of carnivorous ray-finned fishes consisting of 7 families, 30 genera, and 161 species. They feed on small fish and invertebrates. Beyond this, little is known about the biology of most member species because of their nocturnal habits and deepwater habitats. Most live on the continental shelf and continental slope, with some species being found as deep as 2,000 m (6,600 ft).
