There are 5 species of ctenophores (comb jellies) in the White sea, but regularly you can find only two species of them: Beroe cucumis (the photo) and Bolinopsis infundibulum. Ctenophores are the tenderest specimens of macrozooplankton. This is impossible even to touch them without hurting! These animals have the largest cilias in the world. You can see the cilias on photos.
All the comb jellies are predators. Bolinopsis feeds on zooplankton (especially copepods) and Beroe feeds on other comb jellies (wich are usually the Bolinopsis).
