PFS StandardSpiny Eurypterid

Spiny eurypterids are aggressive, tenacious, and utterly unwilling to stop chasing prey, even to their own detriment. These creatures are covered with countless needle-like spikes and can grow to rival the size of ocean mammals like orcas. Sailors often find them clinging to the hulls of ships, as spiny eurypterids mistake them for prey and are too stubborn to let go.

Eurypterid

Source Bestiary 3 pg. 97
Fearsome predators and durable pests, eurypterids are hard-carapaced arthropods sometimes referred to as sea scorpions. Though aquatic creatures, they have robust respiratory systems that allow them to survive indefinitely on land. All eurypterids possess claws as well as stingers that can inject venom.

Sidebar - Treasure and Rewards Acquired Taste

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.
