Eurypterid

Common Name: Eurypterid
Species: Jaekelopterus Euryperus
Time: Silurian
Diet: Carnivore
Temperament: Aggressive if approached

Wild:
Found only in the deepest depths of the waters around the island, Eurypterids are dangerous and adaptable Arthropods. As likely to hunt as they are to scavenge, a Eurypterid rarely has difficulty finding food to keep itself nourished, even at the bottom of the ocean.

A Eurypterid’s threat does comes not directly from its raw strength. Instead, it combines a hard defensive exoskeleton with debilitating poison to powerful effect. The sting of a Eurypterid increases torpor while reducing stamina, quickly rendering its opponent unable to defend itself.

Domesticated:
While Eurypterid are not intelligent enough to be tamed, this doesn't mean they are without utility for tribes. They are a wonderful source of Chitin, and their digestive tract often contain Silica Pearls. They sometimes even have incredibly rare Black Pearls used for manufacturing mysterious technologies, making them among the most valuable creatures on the island.
