Distribution:

Relatively common in the Solitary Islands Marine Park. Generally found throughout the Western Pacific, Southern and Eastern Africa.

Ecological Notes:

Lives on sand flats and coral reef areas, and other warm shallow areas near coasts. It lives successfully in crevices where it is mostly found during daylight hours, but is also found in aggregate groups on the sandy ocean floor or individually hidden under heads of coral.

Additional Notes:

Very long spines cause painful injuries. Is at times host to small fish.
