Color Variety
No two animals look quite alike, and the variety may help to confuse predators that learn to hunt for a particular pattern. The disc is covered in rounded plates and small spines.
Hiding in Crevices
The star lives among rocks, kelp holdfasts and mussel beds, with arms extended into the water to catch food. Daisy brittle stars brood their young in special pouches.
Bioluminescence in Echinoderms
Many brittle stars can produce light, using it to deter predators. See Common Brittle Star.
