Sea scorpions, or eurypterids, were the largest arthropods the world has ever seen.

Jaekelopterus rhenaniae

8.2 feet (2.5 meters) long

18-inch (46-centimeter) spiked claw

They had a pair of pincers, and in some species these too could become very large. Sea scorpions were predators that were in their heyday in the Silurian and Devonian, though they survived into the Permian.


it’s fine.  This is normal.
