Pedal disc present but lacking basilar muscles; column smooth, lacking outgrowths; no marginal sphincter muscle; no distinct siphonoglyphs. Inner tentacles much longer than marginal ones; tentacles non-retractile; each with basal sphincter muscle that allows tentacle to be cast off. Longitudinal muscles of tentacles and column, and radial muscles of oral disc ectodermal; mesenterial retractor muscles weak. Six pairs of mesenteries commonly complete, but more may be present in asexually-produced individuals; more mesenteries distally than proximally. All mesenteries except directives may be fertile. Cnidom: spirocysts, basitrichs, microbasic p-mastigophores, microbasic amastigophores. Spirocysts occur in the column. Capable of swimming by rowing movements of tentacles.
