Welcome to the board.
I was afraid of that other thread. It was amazingly long.
Here is me. Now people know what I react so strongly to people wanting to step on, flush, or otherwise inhumanely dispose of brittlestars. The secret is out. I do consider myself a brittlestar, and not a serpentstar. Size (of arm spines) doesn't matter. I love being in the ocean. You would never find me in freshwater. I like other brittlestars, and most types of seafood. My dream home is a nice stone structure, but I wouldn't mind hanging out in a nice, comfy spongy place.
