| Blue-Spotted Sea Urchin |
Family Diadematidae, Astropyga radiata, 95 feet deep. This pretty reddish brown and white striped urchin is found through the Indo-Pacific and inhabits sand or rubble bottoms of at least 50 ft. or more. In other areas of the Indo-Pacific it can be found in shallow sea-grass beds. Uncommon in Hawai'i, it is rarely seen. The spineless areas of the test contain rows of iridescent blue dots that can expand and contract, sometimes disappearing altogether. Mahi Shipwreck, Wainae, O'ahu, Hawai'i, USA, September 5, 2011. f/5.5, 1/60 second, ISO 80.
