This fish is commonly found in marine environments, particularly in the coastal waters of the Indo-Pacific region.
Description and Characteristics
Kyphosus cinerascens can reach a maximum size of 53.0 cm. The body of this species is typically elongated and compressed, with a distinctive, deep, and somewhat rounded profile. It is recognized by its long dorsal fin, which extends almost the entire length of its back. This fin, along with its characteristic elongated body shape, gives the fish a distinctive, almost sail-like appearance, hence its common names. The color of the fish can range from silvery-gray to brownish-gray, sometimes with a faint reddish tint, especially along the flanks. The underside is lighter in color, often appearing white or yellowish.
Habitat and Occurrence
Kyphosus cinerascens is an adaptable species, inhabiting a variety of marine environments. They are typically found in coastal waters, often in association with rocky reefs, coral reefs, and seagrass beds. Their depth range spans from the surface to a maximum of 45 meters, suggesting they can inhabit both shallow and deeper waters.
Taxonomy
The species Kyphosus cinerascens belongs to the Class: Teleostei, Order: Perciformes, and Family: Kyphosidae. It is a member of a diverse group of fishes known as the “Rudderfishes,” a group that includes about 15 species.
Feeding
Kyphosus cinerascens is an herbivorous fish, primarily feeding on algae and plankton. They are often observed grazing on seaweeds, including benthic algae attached to rocks and substrates. Their diet may also include small invertebrates, particularly those found associated with their preferred habitats.
