Diagnosis Trachymedusae with wide, circular manubrium; mouth circular, without distinct lips; without peduncle; without centripetal canals; usually with eight radial canals (except Varitentaculata which has four), radial canals broad; numerous marginal tentacles of different size, but all structurally alike and arranged in a single series; each marginal tentacle with flexible proximal portion and stiff distal portion; with pendant statocysts. [details] Spelling The correct family name formation would be Halicreadidae according to § 29.3 of the ICZN.
However, as explained in the same article, prevailing usage should be preserved, like in the example Haliotis and Haliotidae. [details]
