Distribution: 

Uncommon in the Solitary Islands Marine Park. Indo-west Pacific, Indonesia, Mascarene Islands, Red Sea and Mauritius. In Australia recorded from the Great Barrier Reef in Queensland south to northern New South Wales.

Ecological Notes: 

Frequents coral and rocky reef areas. Probably rarely seen due to its cryptic habit of secretion under rocks and coral slabs.
