common northern comb jelly

<em>Bolinopsis infundibulum</em>, the common northern comb jelly, is a ctenophore — a gelatinous marine invertebrate in the phylum Ctenophora — found in cold to temperate waters of the North Atlantic and adjacent Arctic seas. Unlike true jellyfish, ctenophores lack stinging cells and instead capture prey using sticky colloblast cells on their tentacles or oral lobes. <em>Bolinopsis infundibulum</em> is a lobate ctenophore that typically inhabits the water column of coastal and offshore marine environments, where it preys on small zooplankton including copepods, fish eggs, and other gelatinous organisms. Its geographic range includes the waters around Denmark, Norway, and Sweden, as well as broader North Atlantic and Arctic waters. The species has not been formally evaluated under the IUCN Red List framework. Biological traits such as lifespan, body size, and diet remain poorly documented in standardized assessments for this species, though it is known to be a carnivore. <em>Bolinopsis infundibulum</em> can occur in significant densities during bloom events and may play a meaningful role in zooplankton dynamics and carbon cycling in northern marine ecosystems.
