sea scorpion
Extinct marine arthropod
Sea scorpion refers to two unrelated creatures.
The eurypterids were prehistoric aquatic arthropods that lived hundreds of millions of years ago—some grew over two meters long, making them among the largest arthropods ever.
Separately, sea scorpions are a family of small, spiny-headed fish found in cold northern waters, named for their superficial resemblance to the extinct creatures.
