Spotnape Cardinalfish, Ostorhinchus jenkinsi (Evermann & Seale 1907)

More Info


Ashmore Reef in the Timor Sea, and the northern Great Barrier Reef, Queensland. Elsewhere the species occurs in the tropical west Pacific: Indonesia east to New Ireland, Papua New Guinea, north to Philippines, south to New Caledonia.
Inhabits clear lagoons with deep sandy slopes, forming schools at night above remote rocky or coral outcrops.


This species has been confused with Ostorhinchus notatus, which does not occur in Australian waters. O. notatus has a pair of narrow black lines running from the snout to the top of the head. Kuiter & Kozawa consider O. notatus to a Japanese endemic.


The species is named for Dr. O. P. Jenkins, of Stanford University.
