More Info

Distribution |
Ashmore Reef in the Timor Sea, and the northern Great Barrier Reef, and reefs in the Coral Sea to One Tree Island, Queensland; also Christmas Island in the eastern Indian Ocean. Elsewhere the species occurs in the tropical, east Indo-west-central Pacific. This solitary species shelters on caves and crevices. |
|
Etymology |
The specific name is from the Latin annosum (= full of years, long lived, aged), in allusion to the plain grey cheek of the new species, which is perhaps reminiscent of that class of elderly hirsute human males sometimes referred to as ‘greybeards’. |
