| Description | Euphemitidae is an extinct family of Paleozoic fossil molluscs of uncertain position. They have isostrophically coiled shells and may be either Gastropoda sea (snail)s, or Monoplacophora.

| Ecospace Comments | LIFE HISTORY: Harper and Rollins (2007): We propose that Euphemites and other bellerophontiform molluscs such as Praematuratroph and Beyrichidiscus make functional and paleoecological sense only if reconstructed with an internal shell adapted to an infaunal mode of life. Linsley (1978) proposed an infaunal mode of life, active burrowing, and carnivory. | |||||||||||||||||||||||||||||||||||||||||||||
