5 (6 votes)
Eurypterids, popularly known as “sea scorpions” are among the more charismatic of extinct invertebrates, and rightly so. Although they weren’t true scorpions these aquatic arthropods were an extremely successful group of predators that dominated both fresh and saltwater environments between 470–252 million years ago. Although most only reached about 8” the largest genus (Jaekelopterus) reached 8’, making them the largest arthropods to have ever lived.
