Tentacle-free combers [1] ( lat. Nuda ) - a class of combers (Ctenophora), which includes a single family - Beroidae [2] . Planktonic ctenophores lacking tentacles. The movement is carried out horizontally using rowing plates. Active predators. Unlike representatives of other orders that feed on planktonic organisms, they eat ctenophores of other species (for example, bolinopsis ) and jellyfish. Extraction is swallowed whole, by severely stretching the pharynx. In turn, they serve as food for fish (for example, such as haddock and cod), large scyphoid jellyfish [1] . A typical representative of the detachment is the ctenophore Beroe cucumis .
