Species of the family Beroidae are specialized predators on zooplanktivorous ctenophores and, occasionally, on salps (L. Agassiz, 1860). The body is mitten-shaped, egg-shaped or conical; extended laterally in the voluminous stomodeum. There are neither tentacles nor tentacular canals (Mayer, 1912) but eight meridional and two paragastric canals. The meridional canals lie under eight rows of ciliary combs. Meridional canals may communicate with each other by means of an anostomosing network of side branches (diverticulae), thus establishing a circum oral canal system. All species have a wide-flaring mouth and stomodeum with powerful cilia on the walls near the mouth, which help the ctenophore to bite and capture prey (Tamm and Tamm, 1993). The polar plate surrounding the sense-organ at the aboral pole is fringed and may have a row of branched papillae. These ctenophores generally have a pink color, while the largest adults are colored moreintensely with a brown tinge (Mayer, 1912).
