Since the body of many species is almost radially symmetrical, the main axis is oral to aboral (from the mouth to the opposite end). However, since only two of the canals near the statocyst terminate in anal pores, ctenophores have no mirror-symmetry, although many have rotational symmetry.

WebCtenophores are almost all pelagic and form part of the "gelatinous plankton". The medusae of Cnidaria are very similar in shape, but move by rhythmic, muscular contractions of the "umbrella". Ctenophores move by ciliary movements. They have 8 bands of compound cilia, "combs", that beat in metachronic waves. how many miles inland am i
