Western Crested Pipefish, Mitotichthys meraculus (Whitley 1948)

More Info


Distribution

Endemic to temperate waters of southwestern Australia; only known from two specimens collected at Flinders Bay, Augusta and Perth, Western Australia; reportedly inhabits sheltered seagrass beds (Posidonia coriaceaI) in 2m.

Features

Dorsal fin 25; Anal fin 3; Pectoral fin 13; trunk rings 20; tail rings 34-35; subdorsal rings 4.0-3.75 + 3.25-3.5 = 7.0-7.5.

Body elongated, trunk moderately shallow, somewhat deeper in adult females than adult males, upper profile slightly convex near dorsal-fin base; head aligned with body; head length 7.9 in SL; snout long, 1.9 in HL; snout depth 4.8 in snout length; median dorsal snout ridge low, entire; opercle without distinct longitudinal ridge in subadults and adults; superior trunk and tail ridges discontinuous; lateral trunk ridge straight, ends near anal ring; inferior trunk and tail ridges continuous; principle body ridges entire, low on trunk, a little elevated on distal half or more of tail; scutella not keeled; without dermal flaps; tail not prehensile.

Dorsal fin origin on trunk, closer to tip of snout than to tip of tail, base of moderate length; pectoral fin base without distinct ridges; anal fin tiny, below front half of dorsal fin; caudal fin very small.

Size

Grows to a maximum length of more than 222 mm SL.

Colour

Brownish with small, dark margined pale spots on scutella of each trunk ring and each ring has a median vertical series of two additional ocelli above the lateral ridge and one below.

Feeding

Unknown – likely to feed on small crustaceans.

Biology

Nothing is known about the biology of this species.

Fisheries

Of no interest to fisheries or aquaculture.

Conservation

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

Remarks

This species is only known from two females caught in south Western Australia, and Rudie Kuiter has suggested that these records may represent range extensions of Histiogamphelus briggsii.

Similar Species

Mitotichthys meraculus differs from M. tuckeri and M. semistriatus in having a more laterally compressed snout with the median dorsal snout ridge extending past the middle of the interorbital and in having the pectoral fin base protruding slightly laterally.

Etymology

Mitotichthys is from the Greek mitis -e (soft), ous, otis (ear) and ichthys (fish).
