Beroe cucumis is a predator and mostly feeds on other comb jellies, particularly Bolinopsis infundibulum; these are pulled into the large mouth and swallowed whole. [3]The comb jelly Mnemiopsis leidyi is an invasive species originally native to the western Atlantic coastal waters that was introduced into the Black Sea in the 1980s, with deleterious results to the ecosystem.
Beroidae is a family of ctenophores or comb jellies more commonly referred to as the beroids. It is the only known family within the monotypic order Beroida and the class Nuda . They are distinguished from other comb jellies by the complete absence of tentacles, in both juvenile and adult stages.
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]
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 .
Bloodybelly comb jelly (Lampocteis cruentiventer) swimmingThis ctenophore differs from all previously described lobate ctenophores in two major ways: (1) all of the meridional canals have blind aboral endings, and (2) the body is penetrated by a deep notch located between the adjacent subtentacular comb rows at the level of the infundibulum.
Comb jelly, Shedd Aquarium, Chicago For a phylum with relatively few species, ctenophores have a wide range of body plans. [ 22 ] Coastal species need to be tough enough to withstand waves and swirling sediment particles, while some oceanic species are so fragile that it is very difficult to capture them intact for study.

Beroe ovata grows to a total length of about 16 cm (6 in). In shape it is roughly oval or cylindrical, but can be flattened like a mitten or deformed. At one end, known as the oral end, is the large mouth and at the other (aboral) end is a statocyst which has a sensory role and is involved in maintaining the animal's equilibrium.
Beroe, commonly known as the cigar comb jellies, is a genus of comb jellies in the family Beroidae. [1] Beroe exhibits bioluminescence. Anatomy.
