What is another word for Order Eurypterida?
Pronunciation: [ˈɔːdə jˈuːɹɪptəɹˌɪdə] (IPA) 
The Order Eurypterida, also known as the sea scorpions, is a group of extinct arthropods that lived in the oceans and freshwater systems during the Paleozoic era. The name Eurypterida comes from the Greek words for "broad wing" and "feather," which refer to the large, flattened appendages these creatures used for swimming. There are several synonymous names for this group, including Eurypterina, Eurypteridans, and Eurypterids. The Eurypterida were among the largest arthropods to have ever existed, with some species reaching over 2.5 meters in length. Despite their fearsome appearance, they were likely passive predators, using their large claws to capture small fish and crustaceans.
