Known as sea scorpions, eurypterids lash out at anything that might be food and are single-minded in their pursuit once they’ve tasted prey. Most eurypterids are capable of scuttling around on land and can exist out of water indefinitely. Unlike rats, eurypterids don’t spread disease or cause much damage to most cargo, traits that have led some captains to experiment with putting eurypterids in their holds to keep rodent populations under control. Alas, one can often tell the ships that employ this tactic by the unusually high number of crew members with missing fingers.
