Beskrivelse

Podocoryna borealis (Mayer, 1900)

This is a relatively common species which is more often observed as a hydromedusa than as a polyp colony. The hydroids grow on different substrates including non-moving objects like polychaete tubes and barnacles, while the hydromedusae occur in surface waters. Unlike any other Podocoryna species in Norway, the oral arms of the hydromedusae of P. borealis are each carrying two clusters of stinging cells.
