The food and feeding behavior of the suctorial nemerteanTortus tokmakovae Chernyshev, 1991, inhabiting the intertidal zone of Peter the Great Bay are studied. Laboratory observations show that this tortus is capable of attacking and consuming 6 species of amphipods, Mysidae gen. sp. mysids andPandalus sp. shrimps. Moreover, the tortuses suck the ti...

We studied the karyotype of the frog sculpinMyoxocephalus stelleri Tilesius (Cottidae) from Peter the Great Bay: 2n=40; NF=46. In the series of two-armed chromosomes, there is a pair of large submetacentric ones, while there are two pairs of large subtelocentric chromosomes in the one-armed series. Ag-NOR staining revealed nucleolus organizer regio...

We studied the fouling of piers and quays in Amurskii and Pos’et bays, the Sea of Japan. The main fouling communities and groupings were identified. They were usually dominated by bivalves, the musselMytilus trossulus and the oysterCrassostrea gigas. The exotic speciesBalanus improvisus was found to naturalize in the fouling on the hydrotechnical s...

In this paper, data are presented on the distribution of dissolved and particulate carbohydrates, proteins, lipids, and nucleic acids (NAs) in the waters of the Kuril Islands on both the Sea of Okhotsk and Pacific Ocean sides. By analyzing discrepancies in the absolute and relative concentrations of these substances, it is revealed that the waters ...

A new species and genus of scleraxonian octocoral from the South Atlantic is described and illustrated. The specimen is characterized by a medulla highly penetrated with solenia and not separated from the cortex by a boundary of longitudinal canals; therefore, it belongs to the family Briareidae. The material studied differs from the genusBriareum,...

Temperature (25, 22, 16, and 12°C) and salinity (32–14‰) effects on the development of the low-boreal holothurianEupentacta fraudatrix were investigated. By studying the desalination resistance of adult holothurians,E. fraudatrix was shown to be a stenohaline species. The lower salinity limit at which both the larvae and adults survived was 22‰. Fe...
