Today I witnessed my long spined sea urchin eating the carcass of my diseased engineer goby. The death of the goby came as no surprise to me. I have been noticed it acting strange and not eating as usual. What did surprise me was finding the sea urchin eating the corpse. Even after pulling it out of its mouth it was still trying to eat some of the flesh that came loose in its spines. Only after offering it some dried seaweed did it stop going for the flesh. Has anyone ever heard of a thing like this before?
