r the first time. All species were found in the same area in the vicinity of the White Sea Biological Station of MSU (Kandalaksha Bay). Halobiotus stenostomus (Eutardigrada) and Batillipes mirus (Arthrotardigrada Batillipedidae) were previously registered in upper sublittoral and and intertidal zones. Recently three more arthrotardigrade species have been found in sandy intertidal at depth 20-30 cm in sediment. Batillipes aff. rotundiculus differs from B. rotundiculus Rho et al. (Korea) by body length, median cirrus length and length of digits. Styraconyx qivitoq (Halechiniscidae, Styraconyxinae) from White Sea differs from S. qivitoq Kristensen & Higgins originally described from Greenland by length of some cirri. Tanarctus aff. ramazzoti (Halechiniscidae, Tanarctinae) differs from T. ramazzoti Renaud-Mornant initially found in the Bay of Biscay by length of spines on fourth legs.
