Data on species composition of ciliates in the small rivers at Khabarovsk and in southern Sakhalin Island are presented. Modified method of sampling was applied with using of samplers and “glass fouling” on the shallows of the rivers. More than 230 samples were collected in the small rivers at Khabarovsk and about 200 samples in the southern Sakhalin. Species composition of the ciliates was determined immediately after the sampling and repeatedly on nutrient media. In total, 86 species of ciliates are identified, mostly belonged to the classes Oligohymenophorea and Spirotrichea. Six eurybionts were found: Coleps hirtus, Paramecium caudatum, Dexiostoma campylum, Colpidium colpoda, Uronema nigricans, and Vorticella convallaria сomplex . The classes Armophorea and Phyllopharyngea were more diverse by species in the area at Khabarovsk but the class Spirotrichea - in southern Sakhalin. In general, faunas of ciliates in two surveyed regions are similar. The highest inter-regional similarity of the species composition is registered between the rivers at Khabarovsk and the Susuya River in Sakhalin (25-33 %, by Jackaroo) that is probably associated with a heightened level of pollution in the Susuya. Most of the species adapt to habitat rapidly, so they are found in different environments: among benthos, plankton, periphyton. Some patterns of the ciliocommunities are discussed.

The fossil impressions of tubes belonging to the bristle worms of the family Pectinariidae and probably the genus Pectinaria Savigny, 1818 was found at the coastal cliffs of the Tartar Strait (Southern Sakhalin) in deposits of the late Miocene Kurasi Formation. Rare mentions of findings of impressions of the polychaetes tubes perhaps may be explained by the fact that such impressions are misidentified as fossils of animals from other higher taxa. Some new data on the bionomics of the recent pectinariids are given and some taphonomical aspects of the group are considered.

Long Term Studies

Results of long-term studies of pink salmon reproduction (spawners run to the rivers, fry downstream migration and adults returns, their survival during the freshwater and marine periods) are widely presented for southern Sakhalin and southern Kuril Islands but were not published until nowadays for northern Sakhalin because of many uncertainties in the data. New series of scientific articles published by A.A. Zhivoglyadov with co-authors pretends to fill this gap, but they content a lot of errors and inaccuracies, so both presented data and conclusions should be considered very carefully.

A New Species

AbstractA new species of marine fish leeches is described and compared with its congeners. Oceanobdella sakhalinica possesses a unique combination of characters: the anterior sucker is small; one of posterior transverse bands on the urosome is very dark; a wedge-shaped patch is located on the posterior sucker; posterior crop caeca are separate for their entire length; accessory glands on the atrium are lacking; five pairs of testisacs are present; the copulatory area and the conductive tissue are lacking. Hosts include a sculpin Myoxocephalus sp. and the blackline prickleback Acantholumpenus mackayi. The leeches were collected in Aniva Bay, southern Sakhalin.

AbstractThe almost complete skeleton of a fossil dreamer, identified as Oneirodes sp., is described from the middle–upper Miocene Kurasi Formation of southern Sakhalin Island, Russia. This is the second fossil skeletal record of oneirodid anglerfishes following those described from the Puente Formation of California, USA. The new specimen possesses morphological features very similar to those of the recent and fossil members of its genus, and cannot be separated from them at the species level. This finding confirms the idea of the high level of speciation of this fish family prior to the middle–late Miocene and demonstrates the wide geographic distribution of the genus Oneirodes already at this time.

The tooth of cow shark of the genus Hexanchus (Hexanchidae) from the Cretaceous (Lower Campanian) deposits of southern Sakhalin Island is described. It is most similar with the teeth, described as Hexanchus microdon (Agassiz, 1835) or H. cf. microdon from the Upper Cretaceous of Japan. Previously shark teeth from the Cretaceous deposits of the Russian Far East not described.

Species composition of macrozoobenthos in lagoons of Sakhalin Island (in total, 637 species) is described on the base of cited data and results of author’s surveys. Its species composition is formed under influence of wide spectrum of environmental factors, as size of lagoon, water salinity, periodicity of connection with the sea and type of the water exchange, river discharge regime, climatic and geographical isolation, etc. Generally, 6 types of lagoons are determined on the coast of Sakhalin differed by composition of benthic fauna: 1) large semiclosed salty lagoon (Lake Busse in southern Sakhalin); 2) small semiclosed salty lagoons with water stratification and periodic connection with the sea (Lake Izmenchivoe and Lake Ptichye in southern Sakhalin); 3) large shallow semiclosed lagoons (in northern Sakhalin); 4) small isolated brackish lagoon (Kuegda Bay in northern Sakhalin); 5) closed oligosaline lagoons (Lake Tunaicha and Lake Aynskoe in southern Sakhalin); 5) isolated freshwater lagoons (Vavaysko-Chibisanskaya lake system in southern Sakhalin). Salty and freshwater lagoons are distinguished by the highest species diversity.
