Brittle starfish, E6, Fiji

Brittle stars are great hiders. Normally you see only a tendril or two peeking out from the shadows.  That's why it was so surprising to see this tiny animal almost all exposed.  The divemaster on the boat thought it was a baby crinoid, not a brittle star.  What do you think?
