If food is plentiful, they can eat 10 times their own weight per day. [78] While Beroe preys mainly on other ctenophores, other surface-water species prey on zooplankton (planktonic animals) ranging in size from the microscopic, including mollusc and fish larvae, to small adult crustaceans such as copepods , amphipods , and even krill .
Abyssal comb jelly (Beroe abyssicola) swimmingBeroe abyssicola is a ctenophore with a flexible, highly muscular body. Being a predator, B. abyssicola uses its muscular body along with its ctene rows to swim and capture its prey, and uses its wide mouth to swallow its prey whole. [2]
This division, after provisional results of morphological and molecular studies, however, probably does not reflect the actual relationships within the ctenophores. The monophyly of Nuda is widely accepted, due to the complete lack of tentacles, and the presence of macrocilia as a common secondary feature, or synapomorphy .

Mertensia ovum, also known as the Arctic comb jelly or sea nut, is a cydippid comb jelly or ctenophore first described as Beroe ovum by Johan Christian Fabricius in 1780. It is the only species in the genus Mertensia.
Pleurobrachia bachei is a member of the phylum Ctenophora and is commonly referred to as the Pacific sea gooseberry. These comb jellies are often mistaken for medusoid Cnidaria , but lack stinging cells .
Coelenterata is a term encompassing the animal phyla Cnidaria (corals, true jellies, sea anemones, sea pens, and their relatives) and Ctenophora (comb jellies). The name comes from Ancient Greek κοῖλος (koîlos) ' hollow ' and ἔντερον (énteron) ' intestine ', referring to the hollow body cavity common to these two phyla.
Leucothea are able to reproduce through self-fertilization and will release hundreds of offspring at a time. Development of these organisms varies by species – for example, through its larval life phase, Leucothea multicornis (of the Mediterranean) passes through a Cydippe-like stage, then a medusiform stage, and then onto the Bolinopsis stage before reaching its Leucothea stage in contrast ...
