Chaetodon gardineri
[3] Chaetodon gardineri is found in the Indian Ocean from Socotra and the Gulf of Aden and along the coastlines of the Arabian Sea from Oman to Sri Lanka.[3] They are omnivorous, feeding on algae, the polyps of stony corals, worms, hydroids, tunicates, crustaceans and other benthic invertebrates.[2] Chaetodon gardineri was first formally described in 1939 by the English ichthyologist John Roxborough Norman (1898-1944) with the type locality given as Muscat.[4] The specific name honours British zoologist John Stanley Gardiner (1872-1946) who was Secretary to the Committee of the John Murray Expedition to the Indian Ocean in 1933-34, on which the type of this species was collected.[5] This species is tentatively placed in the large subgenus Rabdophorus which might warrant recognition as a distinct genus.
