Shark Mermaids are a demihuman subspecies of Mermaid with sharp teeth and the lower body of a shark. Shark mermaids are entirely carnivorous, a rare trait among the predominantly omnivorous mermaids. Their personalities are wild and aggressive. In the past they engaged in pirate-like activities, but more recently they have begun to abstain from piracy. Like sharks, the skeleton in the lower bodies is made of cartilage, making them very delicate. They are mentally weak, as well.
