Most sea urchins have spines covered in a layer of tissue. Pencil urchins- Eucidaris tribuloides shown here- don't. That means the spines serve as a hard substrate for other inverts (barnacles, serpulid worms, bryozoans, hydroids, etc) to settle on. A traveling habitat! #1001jars
It was a good weekend for some Late #Paleozoic field work with @echinerd and @Andrew_G_Flynn with some amazing partially articulated #crinoids!
