Shipwrecker. A charybdis' claws are particularly well suited to puncturing the hulls of ships, and most charybdises have learned that a single large merchant vessel contains enough sailors to make a perfectly sized meal. Often, a charybdis settles in along a well-known shipping route near the shoreline or amid an archipelago of islands where ships are forced along relatively narrow lanes between rocky isles-such locations allow the charybdis to lie in wait and increases the chance of its prey being unable to circumvent its vortex.
