These fabled beasts resemble massive snakes with long rows of finned spines down their back. Temperamental and territorial, sea serpents can capsize a boat with ease, and most won't hesitate to do so when hungry or threatened. Stories abound of aggrieved captains who spend their entire lives hunting down the elusive monster that sunk their ships and took their livelihoods. These hunts rely on rumors and glimpses of the beasts, as few survive the catastrophes wrought by sea serpents.
