The barnacles (Cirripedia: Thoracica) collected by the Viking expedition in chemobiotic benthic communities of the Norwegian and Barents Seas

The barnacles (Cirripedia Thoracica) collected by the Viking expedition in chemobiotic benthic communities of Arctic Ocean-Nyegga area in Norwegian Sea and Håkon Mosby Mud Volcano area in the Barents Sea are investigated. The species (Weltnerium nymphocola in Håkon Mosby Mud Volcano area and Hamatoscalpellum hamatum in Nyegga area) that were found are common inhabitants of the Barents and Norwegian sea benthic communities. The absence of obligatory barnacle fauna that was revealed in investigated chemobiotic benthic communities of the Arctic Ocean shows they are similar to corresponding communities of the Atlantic Ocean, while the specific obligatory barnacle fauna is noted for chemobiotic benthic communities of the Pacific and Indian oceans.

Larvae of Barnacles (Cirripedia: Thoracica) in the White Sea Plankton

The barnacle fauna of the White Sea is briefly described. The morphology of barnacle larvae in this water body is comparatively analyzed. The characters important for the larvae identification are given particular attention. A classification key for the naupliar and cyprid larvae of White Sea barnacles is proposed.     

Barnacles (Cirripedia: Thoracica) from the equatorial East Pacific

Previously unidentified barnacles (Cirripedia: Thoracica) that were collected during the ninth cruise of the R/V Akademik Mstislav Keldysh in the equatorial zone of the East Pacific Ocean from depths of 1422–1490 m are examined. The following species were found in two samples we studied: Amigdoscalpellum costellatum, A. elegans, Arcoscalpellum michelottianum, Annandaleum gruvelii gruvelii, Cristallinaverruca allisoni, and Metaverruca recta. These species are described, illustrated, and compared to the published data. This study extends the previously known areas of distribution of some species and adds further data on their morphology.
