Luminescent Ctenophora (Pleurobrachia pileus, etc.).

Pleurobrachia rhotodactyla, in motion.

In this view the mouth is facing the camera and one tentacle trails off to the left. The ends of the beating comb (ctene) rows can be seen.

The long, retractable tentacles have branches (tentillae) along one side.

This closeup view of the aboral end shows how the tentacle sheaths angle out from the pharynx. A partly retracted tentacle can be seen on the lower left.

A few images of Pleurobrachia bachei swimming. A short movie of the movements the species can make while deploying and manipulating its tentacles can be viewed by clicking here.

Pleurobrachia brachei, about 1 cm diameter, captured from Rosario Strait. This is a side view with the mouth to the right. Some ctene rows, which are beating, can be seen glistening and the row at the top can be seen in side view. The tentacular sheaths and retracted tentacles are to the left.
