Vallicula multiformis Rankin 1956

Vallicula multiformis is a benthic ctenophore, found on algae, rocks or under other organisms. It is possibly common in the region, but infrequently encountered due to its cryptic habits. The adult has no ctene rows and at first look it resembles a flatworm, except for the two long extendable and branched tentacles.

Specimens reach about 12 mm in length.

The species occurs in tropical and subtropical Atlantic.
