Common brittle star

Found masses of these colouful, variable Brittle stars (c 6-8 cms top to tip) in rockpools low on the she shore in Cornwall. Brittle star ID can be tricky, but the colours, relative size of central disc and arms, 5 radiating rows of spines in oral disc, all fit O fragilis perfectly .
