This nondescript blob is the seahare Dolabella auricularia. Commonly known as the blunt-end seahare or shoulder blade sea cat, this algae-eating seahare is popular for its use in the pharmaceutical industry. It is the source of dolastatin (Auristatin), a drug tested for treatment of some non-small cell cancers.
