Ron Silver Blunt Decorator Crab, Camposcia retusa

Shane Siers Ron for the first time, I think I disagree! I've seen hundreds of C. retusa...smaller carapace, longer legs, much smaller/more hidden "face"...and look at it pinching a pair of tucked-in anemones like a boxer crab...I've never seen C. retusa with anything in the chelipeds like that...I'd be willing to bet it's a xanthid of some sort, closely related to Lybia...definitely very cool and unlike anything I've seen!

Ron Silver Thanx, Shane. I went back to my taxonomic keys and found it. This is a Round Crab, known as the Teddy Bear Crab, Polydectus cupulifer.

Shane Siers Hey, same sub-family as Lybia, I was pretty close. What do you use for a key? Is it electronic/sharable?

Ron Silver I don't think so. It's materials I've gathered through-out my career.....actually extends back to my post-grad days. I will however,heartily recommend the Humann/DeLoach volumes on tropical Pacific reef creatures and reef fish.

Shane Siers Yeah, I've got their Reef Creatures volume thx.

Michael Tan Cheang Hin Is Teddy Bear Crab...
