More Info


Distribution

Known from the tropical Indo-West Pacific from Indonesia to Samoa; in Australian waters, known from off Yonge Reef, Great Barrier Reef (Qld); in sheltered coral reef habitats, usually in crevices with sponges at about 10-38m.

Features

Meristics: D 22-26; P 20-23; Trunk rings 15; Tail rings 20-22.

Head and body: Head length 3.4-3.9 in SL, snout long, length 1.7 in HL, snout depth 5.5-7.0 in snout length; median dorsal snout ridge low; trunk longer than tail, trunk and tail ridges distinctly notched between rings; odontid processes (tooth-like structures) prominent. Male brood pouch folds encompass 13 rings; scutella not keeled; males (females ?) with knoblike projections below lateral ridge on posterior margins of most trunk rings; ridges rough, finely denticulate to serrate.

Size

To 8 cm TL

Colour

Pale whitish to yellow, body with distinct irregular dark bars encircling trunk, mostly on ring margins, tail usually with spots; opercle with dark spots; dorsal and pectoral fins with light basal scattering of chromatophores.

Feeding

Likely to feed on small crustaceans, however, distinct odontid processes (tooth-like structures) on jaws may facilitate grazing.

Biology

Reproduction: Ovoviviparous (gives birth to live young). Males may be brooding at a length of 38 mm.

Eggs: eggs are brooded by the males in an enclosed pouch on the underside of the trunk; usually in a single layer of two parallel rows.

Larvae: Undescribed, but likely to be pelagic and morphologically similar to adults at birth.

Fisheries

None known.

Conservation

Marine listed under the Australian Environment Protection and Biodiversity Conservation Act 1999. (EPBC Act)

Similar Species

Similar to several Choeroichthys species; C. cinctus differs from C. sculptus in having a keeled scutella and higher trunk ring counts (18 versus 15); differs from C. smithi in the bi-coloured dorsal fin and in having more trunk rings (18 versus 15); C. brachysoma has a shorter head length and fewer tail rings, 18-19 compared to 20-21 in C. cinctus

Etymology

Choeroichthys is from the Greek choiros (pig) and ichthys (fish). The specific name cinctus is from the Latin cintum (girdle, belt) in reference to the barred colour pattern of preserved males.
