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.
To prove that the structures behave as lenses, Aizenberg shined a light through the skeleton of the brittlestar
Ocean warming and acidification; implications for the Arctic brittlestar
2008) showed a reduction in larval survival and size, as well as increased larval abnormalities in the brittlestar
Ophiothrix fragilis at pH 7.
In these waters they feed on worms, crustaceans, brittlestars
and sand eels.
By studying the brittlestar
, we can learn about low-cost ways of forming single crystals in complex shapes at low temperatures.
Autotomy and regeneration in the brittlestar
Finally they've found the answer: The brittlestar
doesn't have eyes--it is an eye
The analysis of bony structures in the arms of the brittlestar
Ophiocoma wendtii showed the presence of a regular array of spherical microstructures that look like lenses.

species have been used to study autotomy mechanisms (Dobson, 1988; Charlina and Dolmatov, 2008; Charlina et al.
However, higher rates have been reported for some infauna--85% for a brittlestar
in South Carolina (Stancyk et al.
