Food Habits
All known ctenophore species are carnivorous, feeding on rotifers, small crustaceans (including copepods, amphipods, and euphausiids), and the planktonic larvae of many other species (including clams and snails). Beroids are known to feed on other ctenophores. Depending on the body structure of the specific species, prey may be captured with long tentacles or with a mucosal layer on the body surface, which carries the prey to the mouth by ciliary currents. Colloblasts, located on the animals' tentacles or lobes, aid in prey capture; species of genus Haeckelia do not have colloblasts, and instead use sequestered nematocysts from their cnidarian prey. Species of Euplokamis have prehensile side branches on their tentacles, which wrap around and snare prey. (Brusca and Brusca, 2003; Haddock, 2007; Mills, 2010)
