Passaloteuthis is a genus of belemnite, an extinct group of cephalopods.[1] Belemnites are typically known for having about 40 micro-hooks on each one of its appendage. However, Passaloteuthis is notable for being associated with a pair of mega-hooks known as onychites. These hooks are tentatively interpreted as male-specific features, though their exact function is still unknown.[2]
