Eurypterid

Common Eurypterid (Creature -1), Spiny Eurypterid (Creature 5)

The meat of a eurypterid is generally considered an acquired taste, as the flesh turns gelatinous when heated, but those who enjoy it claim its taste falls somewhere between sweet shrimp and crab. A market exists for eurypterid meat, especially for more dangerous varieties like the spiny eurypterid, but supply remains low as most fishermen won't risk baiting a creature that could ruin an entire day's catch.
