The Venus girdle (Cestum veneris) is a comb jelly in the family Cestidae. It is the only member of its genus, Cestum,[1] and is also the largest of all known ctenophores.
Venus girdles resemble transparent ribbons with iridescent edges. They may grow up to a metre in total length. Canals run the length of the ribbon in which bioluminesce activates when disturbed.[2]
This species is pelagic and is found in tropical and subtropical oceans worldwide in midwater.[2]
These animals swim horizontally using muscular contractions as well as the beating of the comb rows. The oral edge leads. They eat small crustaceans.[2]
