WebFeb 22, 2024 · Feeding strategies may differ depending on the prey availability, which is itself fluctuating with the environmental parameters and some species, such as Centropages hamatus and Acartia spp. can switch feeding behavior from passive to active ( Tiselius and Jonsson, 1990; Kiørboe et al ., 1996 ). Ctenophores are found in most marine environments: from polar waters to the tropics; near coasts and in mid-ocean; from the surface waters to the ocean depths. The best-understood are the genera Pleurobrachia, Beroe and Mnemiopsis, as these planktonic coastal forms are among the most likely to be collected near shore. No ctenophores have been found in fresh water.

Sessile polyps depend for food on organisms that come into contact with their tentacles. Ctenophores (Fig. 1) are unique among animals in their possession of large macrocilia and a particular type of adhesive cells known as colloblasts. They use these in a variety of ways, including for locomotion and feeding.
