Mycteroptidae are a family of eurypterids, an extinct group of merostomatan arthropods commonly known as "sea scorpions". The family is one of three families contained in the superfamily Mycteropoidea (along with Hibbertopteridae and Drepanopteridae), which in turn is one of four superfamilies classified as part of the suborder Stylonurina.
Mycteroptids were sweep-feeding eurypterids only known from the Late Carboniferous.
Mycteroptids were medium medium-sized to fairly large mycteropoids with parabolic prosoma and a hastate telson with paired ventral keels. They had a culticular ornament of scales or mucrones and unlike the hibbertopterids, appendage IV was non-spiniferous. The first and second opisthosomal tergites were strongly developed and elongated. The heads of mycteroptids were subtrapezoid in shape with small compound eyes.
Mycteroptids only used appendages II and III to capture prey, whilst hibberopterids used II, III and IV.
The three genera included in the Mycteroptidae, Mycterops, Woodwardopterus and Megarachne might represent different ontogenetic stages of each other based on the sizes of the referred specimens and the patterns of mucronation. This would sink the genera Woodwardopterus and Megarachne into Mycterops.
