Heteroclinus roseus Gьnther, 1861, Freycinets Harbour, Western Australia.
OTHER COMMON NAMES
May reach maximum lengths of 5.7 in (145 mm). The rosy weedfish is distinguished from other Heteroclinus species by having a black spot, bordered above and below by a white stripe, on the pectoral fin-base.
Primarily anti-subtropical in
, occurring north of approximately 20° N latitude and south of roughly 20° S latitude, and absent in tropical equatorial waters. A northern population occurs in Japan and a disjunct southern population living around the southern half of Australia, Lord Howe Island, Kermadec Islands, New Caledonia, and Vanuatu.
The rosy weedfish lives on rocky reefs from the intertidal zone to depths of 115 ft (35 m).
Rarely seen underwater owing to its very cryptic coloration. Sits on the bottom using its pelvic fins as supports to lift the head.
FEEDING ECOLOGY AND DIET
Predatory, probably feeding on small benthic invertebrates.
The presence of an intromittent organ in males suggests that it (like all other clinids in the Indo-Pacific) is ovoviviparous.
Not listed by the IUCN.
