Traits

The teeth in this leech's mouth have developed into a single point on the upper and lower jaw, resembling the beak of a squid. 

These leeches will always have an overbite, and the top tooth is visible when the mouth is closed.  Squid-toothed leeches are experts at piercing holes in things, whether it be hard shells, seafood, containers, or plastic recycling bins.  The 'beak' is very dexterous!
