Cookeolus japonicus is a species of fish in the family Priacanthidae, the bigeyes and catalufas. It is the only extant species of Cookeolus , [1] except for C. spinolacrymatus , an extinct Late Pliocene fish known from a fossil specimen collected in Okinawa, Japan. [2]
C. japonicus is found throughout the tropical and subtropical oceans, except the East Atlantic. In the Indo-Pacific its distribution extends from South Africa to Japan to Australia, in the eastern Pacific from Mexico to Peru, in the West Atlantic from Canada to Argentina, and at Saint Helena in the South Atlantic. [3] Common names for the fish include longfinned bullseye, deepwater bullseye, big-fin bigeye (English), buloog (Afrikaans), deek (Arabic), baga-baga (Cebuano), bukaw-bukaw (Hiligaynon), siga (Tagalog), beauclaire longue aile (French), chikame-kintoki (Japanese), fura-vasos alfonsim (Mozambican Portuguese), and catalufa aleta larga (Spanish). [4]
This species reaches up to 69 cm (27 in) long, but is more often around 30 cm (12 in). Specimens weighing 5 kg (11 lb) have been noted. [3] Fish of this family are known for their thick scales and large eyes, which take up about half the length of the head. This species is the largest in the Priacanthidae. It can also be distinguished from others in the family by its long pelvic fins. These are longest, relative to body size, in smaller individuals. The tail fin is rounded. The fish has an elongated oval shape as an adult and is laterally compressed. It is red in color, and all the fins may be yellowish except the pectorals, which are pink to colorless. The membranes between the dorsal spines may be slightly darkened to totally black, and the long pelvic fins may be quite dark. The juvenile is not well known but it is likely silver in color. The appearance of the fish shows some geographical variation, mainly in size. [5]
The life span of the fish is up to about 9 years. [3]
Many catalufas commonly live in the waters around islands. [6] This species lives around reefs at depths up to 400 m (1,300 ft), though it is usually found between 165 and 200 m (541 and 656 ft). It lives around rocks and ledges with invertebrate life such as sponges and corals. [3]
Its diet includes pelagic crustaceans, [3] especially crabs. [5]
Predators of the fish include yellowfin tuna (Thunnus albacares). [5]
This fish is parasitized by the copepods Parashiinoa cookeola and Caligus cookeoli . [7]
The cutlassfishes are about 45 species of predatory fish in the family Trichiuridae of the order Scombriformes found in seas throughout the world. Fish of this family are long, slender, and generally steely blue or silver in colour, giving rise to their name. They have reduced or absent pelvic and caudal fins, giving them an eel-like appearance, and large fang-like teeth.
Sweepers are small, tropical marine perciform fish of the family Pempheridae. Found in the western Atlantic Ocean and Indo-Pacific region, the family contains about 26 species in two genera. One species is the target of subsistence fisheries in Japan, where the fish is much enjoyed for its taste. Sweepers are occasionally kept in marine aquaria.
Sebastes is a genus of marine ray-finned fish belonging to the subfamily Sebastinae part of the family Scorpaenidae, most of which have the common name of rockfish. A few are called ocean perch, sea perch or redfish instead. They are found in the Atlantic and Pacific Oceans.
The Priacanthidae, the bigeyes, are a family of 18 species of marine ray-finned fishes. "Catalufa" is an alternate common name for some members of the Priacanthidae. The etymology of the scientific name 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.
The bigeye sand tiger is an extremely rare species of mackerel shark in the family Odontaspididae, with a possible worldwide distribution. A large, bulky species reaching at least 3.6 m (12 ft) in length, the bigeye sand tiger has a long bulbous snout, large orange eyes without nictitating membranes, and a capacious mouth with the narrow teeth prominently exposed. It can be distinguished from the similar smalltooth sand tiger by its teeth, which have only one lateral cusplet on each side, and by its uniformly dark brown color.
Argyrosomus is a genus of marine ray-finned fishes belonging to the family Sciaenidae, the drums. The fish in this genus are large and are commonly targeted as game fish.
Heteropriacanthus, the glasseyes or glass bigeyes, are a genus of the bigeye family found in all tropical seas around the world. It occasionally makes its way into the aquarium trade. It grows to a size of 50.7 cm (20.0 in) in total length.
The popeye catalufa, also known as the bigeye soldierfish, is a species of marine ray-finned fish in the family Priacanthidae, the bigeyes. This fish has an overall dusky orange to red colour with white markings. The dorsal fin appears feathery while rest of fins have black margins. It occurs in the eastern Pacific, where it is found from Oregon to Chile. It occasionally makes its way into the aquarium trade. It grows to a size of 34 centimetres (13 in) in length. This species is nocturnal and shy, preferring deeper waters off islands. It has been recorded associating with squirrelfishes and cardinalfishes but the popeye catalufa goes as deep as 76 metres (249 ft), deeper than its associated species. This species has been recorded from rocky habitats at depths of less than 5 metres (16 ft) to over 100 metres (330 ft). It is a carnivorous species and, when kept in captivity, is known to feed on worms, crustaceans and brittle stars.
