ABSTRACT: Hydroids are common components of fouling communities in the sea, but they are often inconspicuous and easily overlooked. In such cases, the appearance of their medusae in plankton is an obvious indicator of the species’ presence in a locality. In this study, we present the first record of medusae Bougainvillia principis from the White Sea. We hypothesize that hydroids of the species B. principis inhabit the White Sea, as well, but they do not usually produce medusae and consequently the species does not exhibit sexual reproduction in the White Sea.
