|Glasseye, Heteropriacanthus cruentatus|
The Priacanthidae, the bigeyes, are a family of 18 species of marine fishes. "Catalufa" is an alternate common name for some members of the Priacanthidae. The etymology of the scientific name (prioo-, to bite + akantha, thorn) refers to the family's very rough, spined scales. The common name of "bigeye" refers to the member species' unusually large eyes, suited to their carnivorous and nocturnal lifestyles. Priacanthidae are typically colored bright red, but some have patterns in silver, dusky brown, or black. Most species reach a maximum total length of about 30 cm (12 in), although in a few species lengths of over 50 cm (20 in) are known.
Most members of this family are native to tropical and subtropical parts of the Indian and Pacific Oceans, but four species (Cookeolus japonicus, Heteropriacanthus cruentatus, Priacanthus arenatus, and Pristigenys alta) are found in the Atlantic. They tend to live near rock outcroppings or reefs, although a few are known to inhabit open waters. Many species are found in relatively deep waters, below depths reachable by normal scuba diving. Some species are fished for food.
