👉 Epizoanthidae are a family of freshwater, saltwater, and marine crustaceans that belong to the order Apicomplexa. They are known for their unique, highly specialized body plan characterized by a single, long, slender body with two pairs of appendages (legs) that are attached to each side of the body. This structure allows them to efficiently feed on a variety of prey, including crustaceans and mollusks.
