An echinothuriid sea urchin. Phormosoma sp., possibly P. bursarium or P. rigidum -- the former has curved aboral spines, and the ones in the images are straight, so a more likey this is P. rigidum (assuming it is a described species). Note the dark, swollen spine tips marking the poison-bearing spines. Also, hypertrophied pedicellariae around the periphery. Notice what appears to be a little holothuroid to the right.
