Thanks all, especially for the pics. My granddaughter (4) watched a brittle star being fed in an aquarium and was fascinated. She told me about it and wanted me too see one on my next dive trip. I think that I can pretty much assure her that I will at this point.
When my daughter was about 6 and before I started diving, I used to snorkel out behind Blue Angel (La Perla at the time) and bring up brittle stars and stuff for her to play with in the shallow water. Once I picked up a bristle worm, which taught me a valuable lesson.
