Common name: Brown comb jellyClass: Nuda Order: BeroidaFamily: Beroidae

The Beroe ovata, also known as the Brown Comb Jelly, has a barrel shaped body. Its body is reddish-brown to orange with rows of “combs” running along its body. This brown comb jelly fish weighs about 0.85 g and its body ranges in length from 10 to 120 mm. This organism uses cilia for movement and feeding.They have been found at depths ranging from just below the surface at 0.5 meters to 1719 meters below the surface. This means that Beroe ovata is capable of surviving in the epipelagic zone, mesopelagic zone, and the upper range of the bathypelagic zone. Basically, this means that the Brown Comb Jelly is able to live in areas where there is no sunlight at all. Beroe ovata naturally inhabits the Atlantic Ocean and coastal waters near both the United States and Canada as well as in the Gulf of Mexico and European waters.
Beroe ovata primarily feeds on other ctenophores, including Bolinopsis infundibulum, Cestum veneris,Mnemiopsis leidyi, and various species of Ocyropsis.
People may believe that Beroe ovate is dangerous but as a matter of fact, the brown comb jelly poses no threat to humans at all. In fact, in the 1980s, these little unknown creatures helped us solve a huge problem with the invasive species, Mnemiopsis leidyi. When Beroe ovate was introduced, it consumed up to 10% of the invasive species’ population daily – helping Engraulis encrasicolus, an anchovy species, flourish.
