Re: Chelidonura varians - shipping stresses?

I hope you didn't take offense to the post. I understand your frustration. The animal in question is a true brittlestar and your statement about it exclusively feeding on small specs of detritus isn't quite accurate. Brittlestars will eat meat. They'll grab hold of a large chunk of shrimp and bring it with them to their hiding spot.

Thanks for the words of good luck and the information on their defenses. I'll look out for him and hope he turns up.
Thanks.

Dear James,
I have a lot of messages from aquariists, many of them which I am unable to post as they would completely clog up the Forum. There are some good general books readily available but many, not including you, don't seem to make any effort to find out about the animals they have in their care or are misled by those in the trade who sell animals to them. Concerning brittle star feeding, I am not an expert. Most are particle feeders and I guess they treat a hunk of shrimp as a very large particle. I'm not sure how they eat it as my understanding is that unlike starfish, which evert their stomachs out over their food, in brittle stars the food is ingested by ciliary movement. The point I was making is that I don't think your Chelidonura is in danger from the brittle star.
Best wishes
Bill Rudman
