Platyceratidae is an
mollusks. This family may belong in the Patellogastropoda or the Neritimorpha.[2]
Platyceratids are known for the complex
gonads or the hindgut.[3][4] Previous authors have suggested that platyceratids were commensalists which fed on crinoid fecal matter without harming the crinoid, but more recent studies have shown that platyceratids did have a negative effect on their crinoid hosts as would be expected if they were actively parasitic.[5] It has been suggested that the large spines present on many species of crinoids served to deter predators who might damage or harm the crinoid in an effort to feed on the platyceratid snails infesting it.[4]
This is the only family in the superfamily Platyceratoidea.
