Eurypterus remipes (Sea Scorpion) - New York w/ stand 76740e6d2a4e5cdac8c15dc618d3f154 All members of the groupEurypterids, commonly known as Sea Scorpions, are an extinct group of arthropods that are related to arachnids and include the largest known arthropods to have ever lived. Prevalent during the Silurain and Devonian ages, eurypterids were segmented aquatic arthropods, with compound eyes, and two club like claws. Some species exhibit toothed claws and may therefore have been predators. Though they are globally dispersed, eurypterid fossils are uncommon
