The Papua New Guinea shell-less mollusc Dolabella auricularia has been found to contain a series of green to blue-green chlorins. One of these compounds was found to be the nickel chelate tunichlorin [1] which was isolated previously only from the Caribbean tunicate Trididemnum solidum. Discovery of tunichlorin [1] in a sea hare suggests that its occurrence in algae-consuming marine animals may be more common than earlier realized, and it may have a role in electron transfer or other metabolic processes.
