Neotrypaea
ghost shrimp
Neotrypaea is a genus of ghost shrimp in the family Callianassidae, established by Manning & Felder in 1991. The genus contains at least 16 recognized species distributed across the Pacific coasts of North and South America and Asia. Species within this genus are characterized by pronounced sexual dimorphism in claw morphology, particularly the development of enlarged master claws in males. They are obligate burrowers in marine and estuarine sediments, where they function as ecosystem engineers through their bioturbation activities.
