type of sea urchin?

Haven't seen anything like it in my critter ID books, but has an urchin-like appearance.

Most definitely a worm. Over to you, Leslie.

Well, that would certainly explain why I couldn't find it anywhere in the urchin section!

Now that I'm using the right book, it looks like a Variegated Feather Duster.

Thanks for the pointer, I'm still a bit new at all this!

Variegated feather duster? You must be using Humann & DeLoach. The animal in your picture certainly looks like the one in the book. The striped pattern occurs in other species too.

Leslie,

Yep, Humann and DeLoach. The only ID books I have at the moment are the Reef Series set (Reef Fish, Reef Creatures, and Reef Coral).
