A review of the genus
The collection of pycnogonids from the northern Atlantic Ocean and the southern Norwegian Sea resulted from studies in expeditions of the Shirshov Institute of Oceanology (1982-2002) was analyzed. In the northern Atlantic, 13 species were identified. Two species

The structure of chaetae in thirty-one species of the family Polynoidae belonging to 29 genera were studied using a scanning electron microscope. Six main types of chaeta structure were distinguished. Different types of chaetae were arranged in morphological rows, which well correlated with the current hypotheses of Polynoidae evolution. The type of chaeta structure is a distinct systematic characteristic on the generic level. It can be also used for higher taxonomic levels.
