The development of the brittlestar
Ophiopholis aculeata (O.
The team, together with scientists from Israel's Weizmann Institute and the Natural History Museum of Los Angeles County, discovered that chalk-like calcite crystals in the skeletons of brittlestars
have a dual function, acting as armour as well as optical receptors for an all-seeing compound eye.
For example, light shining into a brittlestar
's surface lens gets focused by a second lens below the sphere.
(2008) showed a reduction in larval survival and size, as well as increased larval abnormalities in the brittlestar
Ophiothrix fragilis at pH 7.9 and 7.7.
In these waters they feed on worms, crustaceans, brittlestars
and sand eels.

Scientists studying a bizarre sea creature called the brittlestar
, cousin to the starfish, have pondered that question for decades.

Previously, we presented a brief description of stomach lining regeneration after central disk autotomy in the brittlestar
Amphipholis kochii (Frolova and Dolmatov, 2006).
However, higher rates have been reported for some infauna--85% for a brittlestar
in South Carolina (Stancyk et al., 1994) and 20%-40% for a maldanid in France (Clavier, 1984).
