Barrelfishes

Barrelfishes are a genus of marine fish belonging to the family Centrolophidae. They are characterized by their deep, compressed bodies, often giving them a rounded or barrel-like appearance, which is the origin of their common name. Barrelfishes are found in temperate and tropical waters worldwide, inhabiting both continental shelves and oceanic islands. They are typically solitary and pelagic, meaning they live in the open ocean.

These fish are carnivorous, feeding on smaller fish, crustaceans, and cephalopods. Their diet and hunting behavior can vary depending on the species and their specific habitat. Barrelfishes are generally of moderate size, though specific lengths can differ between species. They possess a single dorsal fin and a somewhat elongated anal fin. Their coloration can range from silvery to dark brown or grey, often with subtle patterns.

Reproduction in barrelfishes typically involves external fertilization, with females releasing eggs into the water column, which are then fertilized by the males. The larval and juvenile stages are often planktonic and can be found far from shore. While not extensively fished for commercial purposes, some species are caught as bycatch in other fisheries and are sometimes consumed locally. Information on their conservation status is limited for many species, though they are generally considered to be of least concern.
