Etelis carbunculus, the deep-water red snapper, ruby snapper, longtail snapper, or ehu,

ray-finned fish, a snapper belonging to the family Lutjanidae. It is found in the Indo-Pacific
region.

Description

Etelis carbunculus is an elongated fish with a small head and a large eye, the space between the eyes is flat. The mouth extends back as far as the middle of the eye and the jaws are each equipped with a single row of conical teeth with 1 or 2 pairs of enlarged canines at the front. The

total length of 65 cm (26 in) is more typical.[2] The overall colour of this species is reddish to pinkish with a whitish abdomen. There are red margins to the dorsal fin and the caudal fin which has a white tip to its lower lobe.[5]

Distribution

Etelis carbunculus has a wide distribution and can be found throughout the Indian and Pacific Oceans. It occurs from the

Cocos (Keeling) Islands.[5]

Habitat and biology

Etelis carbunculus is found over rock substrates and rocky reefs at depths between 90 and 400 m (300 and 1,310 ft), in or around the benthos. It has been reported forming aggregations. It is a predatory species feeding on fishes,

crustaceans and zooplankton. They breed all year round in Vanuatu, spawning peaking there in November.[1]

Parasites

The

parasitise E. carbunculus.[6] These parasites have what is possibly the longest valid generic name of the zoological nomenclature for a non-fossil organism.[7]

Taxonomy

Etelis carbunculus was first formally

type locality given as Mahé in the Seychelles.[8] At the time it was the only species in the genus Etelis so it is the type species of that genus.[9] The specific name carbunculus is a “ruby red precious stone”, a reference to the reddish colour of this fish.[10]

Fisheries

Etelis carbunculus JNC2427 (Lutjanidae)

Etelis carbunculus is a target for fisheries throughout its range and the stocks have been reported to be declining in some regions. It is caught using bottom longlines and deep handlines and is an important food fish. In Australia its stock is managed under the Western Deep Water Fishery.[5] The caught fish are sold fresh or frozen.[4]
