Hydrozoer: Podocoryna areolata.

This is a relatively common species, although it is more often recorded as a hydromedusa than as a polyp. The hydroid colonies of Podocoryna areolata grow preferably on snail shells that are inhabited by hermit crabs, while the hydromedusae occurs in surface waters. Unlike any other Podocoryna species in Norway, the manubrium of the hydromedusae of P. areolata has four basal pouches that extend a little along the radial canals, giving the impression of a cross when seen from above.
