Acanthurus randalli, commonly known as Randall’s Surgeonfish, is a species of fish belonging to the surgeonfish family, Acanthuridae. It is a relatively small fish, reaching a maximum size of 18.0 cm. This species can be found inhabiting a variety of marine environments, with a depth range extending from 1.0 to 20.0 meters.
Description & Characteristics
Acanthurus randalli is characterized by its distinctive color pattern. The body is predominantly yellow with a series of dark brown vertical bars, which are typically wider than the spaces between them. The head is a paler yellow, and the dorsal fin is edged in black.
Habitat and Occurrence
Acanthurus randalli is a reef-associated species, typically inhabiting coral reefs and rocky reefs in the Indo-Pacific region. Its depth range of 1.0 – 20.0 meters indicates that this surgeonfish is found in both shallow and deeper water. Its preference for reefs places it within the neritic zone, the marine zone extending from the shoreline to the edge of the continental shelf.
Taxonomy
Acanthurus randalli belongs to the Class: Teleostei, Order: Acanthuriformes, and Family: Acanthuridae. This means it is a bony fish, a member of the surgeonfish order, and part of the surgeonfish family, which is known for the sharp scalpel-like spines located near their tails.
Feeding
Acanthurus randalli is herbivorous, feeding primarily on algae. This grazing behavior plays a crucial role in maintaining the health and balance of the reef ecosystem.
