Cestum veneris Lesueur 1813

Cestum veneris is an oceanic ctenophore rarely seen in the São Sebastião Channel. Its body is very flattened in the tentacular axis and laterally elongated in the stomodeal axis, giving the animal the appearance of a ribbon. The edges of the body are rounded and the entire oral surface is recovered by oral tentacles. Tentacular ctene rows are almost inexistent. Apical organ delimitates the aboral extremity of the body. No axial tentacles present in adult.

Adult specimens can reach 200 cm wide.

The species is distributed worldwide in all of the oceans.
