Priacanthus hamrur, the lunar-tailed bigeye, goggle eye, or moontail bullseye, is a species of marine fishes belonging to the family Priacanthidae.
This species is uncommon but widespread in the Indo-Pacific, from the Red Sea and southern Africa to French Polynesia, southern Japan, and Australia. It has been reported also from Easter Island. [2] [3] Two records have been reported from the Mediterranean Sea off Tunisia and Turkey respectively. [4]
Priacanthus hamrur is a reef-associated species, living in tropical marine waters on outer reef slopes and rocky areas and in lagoons at depths of 8 to 250 meters, but most commonly from 30 to 50 m. [2] [1]
At sexual maturity the size of Priacanthus hamrur reaches 18–19 cm (7.1–7.5 in) in males, 19.1–20.0 cm (7.5–7.9 in) in females, [1] but males can reach a maximum length of 45 cm. [2] The body of the Crescent-tail Bigeye is relatively deep, strongly compressed laterally. The eyes are very large and red (even in case of silver livery). The mouth is oblique with a protruding lower jaw and small conical teeth. The extremity of the lower lip is above the median line of the body. [5] The dorsal fin has 13 to 15 soft rays. The pelvic fins are very large. The caudal fin has a concave indented margin which may be crescent-shaped (hence the common name). [2]
The body of these fishes goes through various phases of color, which may vary from orange to entirely red or entirely silver, or silver with broad six red bands (the first red bar crosses the eye). [5] It is also capable of quickly changing the color. Sometimes it has a row of about fifteen small dark spots along the lateral line [5] or large spots on upper side. The fins are red to light pink. [2]
This species is rather similar and can be confused with Priacanthus blochii and with Heteropriacanthus cruentatus . Both these last species have the caudal fin only slightly rounded. [5]
Priacanthus hamrur feeds primarily at night on small fishes and small crustaceans and various invertebrates (small cephalopods, shrimp, crabs, polychaete worms, etc.). [2] [1] [5] These fishes can be found throughout the year, with a peak in the month of August. [6] Eggs, larvae and very young juveniles are pelagic. [5] These fishes usually live solitary, but the may also form small aggregations and sometimes large schools in the open waters. [1]
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 trevally, also known as the bigeye jack, great trevally, six-banded trevally and dusky jack, is a species of widespread large marine fish classified in the jack family Carangidae. The bigeye trevally is distributed throughout the tropical waters of the Indian and Pacific Oceans, ranging from South Africa in the west to California and Ecuador in the east, including Australia to the south and Japan in the north. The bigeye trevally is best distinguished by its colouration, having a dark second dorsal fin with a white tip on the lobe, and also possessing a small dark spot on the operculum. Other more detailed anatomical features also set the species apart from other members of Caranx. The species is known to grow to a length of 120 cm and 18 kg.

Platax teira, also known as the teira batfish, longfin batfish, longfin spadefish, or round faced batfish is a species of marine ray-finned fish belonging to the family Ephippidae, the spadefishes and batfishes. This species is found in the Indo-West Pacific.
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.
