The sea gooseberry ( Pleurobrachia pileus ) belongs to the rib jellyfish (Ctenophora). It can be up to 3 cm high and has a spherical to ovoid shape with eight characteristic longitudinal ribs. It has two tentacles up to 75 cm long with which it catches plankton . She can also catch organisms directly from the surface of the water with her mouth open. The sea gooseberry is considered to be cosmopolitan , although its occurrence in arctic waters is not guaranteed. The occurrence of the sea gooseberry is strongly dependent on the ocean currents and its tolerance with regard to salinity and temperature is so great that it tolerates both penetration into the brackish water of the Baltic Sea and freezing.
