Ocyropsis crystallina (Rang 1828)

Ocyropsis crystallina is an oceanic ctenophore rarely seen in the São Sebastião Channel. It has two lobes with strong musculature, which act as "wings", fast moving the animal away from the source of disturbance. The apical organ delimitates the aboral extremity of the body. No axial tentacles present in adult.

An adult specimen 50 mm wide was collected in the São Sebastião Channel.

The species is distributed worldwide in tropical and temperate oceans.
