Esperiopsis koltuni, a new species of the sponge family Esperiopsidae, is described from deep water of the Sea of Okhotsk. The new species has a unique growth form: there is a basal plate with radiating cylindrical branches, whose oval flat distal parts bear filament-like outgrowths. Megascleres are arranged differently in the main part of branches and in their distal flat parts. The dermal membrane contains isochelae with protruding alae and abundant sigmancistras. Microscleres are represented by large anchorate spatuliferous isochelae, small isochelae, sigmas and sigmancistras. Esperiopsis koltuni sp. nov. is hermaphroditic, with parenchymella larva. The larval skeleton consists only of sigmas and sigmancistras. Esperiopsis koltuni sp. nov. can be easily distinguished from other Esperiopsis species by dimensions and combination of spicule types. In particular, it is the only species in the genus with three different size categories of styles. The new species lacks the aquiferous system, has a characteristic body plan with symmetrical lateral expansions, an unusual arrangement of microscleres in the dermal membrane and true sigmancistras. Moreover, prey capture by a filament-like outgrowth of the flat distal part was observed. All of these characteristics indicate that Esperiopsis koltuni sp. nov. is a carnivorous sponge.

Specific Identity

A new species of the pandalid shrimp genus Pandalus Leach, 1814, Pandalus ivanovi n. sp., is described on the basis of material from the Sea of Okhotsk off eastern Sakhalin, at depths of 150–200 m. It is morphologically closest to Pandalus hypsinotus Brandt, 1851, a commercially important species widely distributed in the northern North Pacific. Because of the strong similarities between the new species and P. hypsinotus, we have examined syntypes of the latter species in order to confirm the specific identity. The new species can be distinguished from P. hypsinotus by the more strongly upturned rostrum, the relatively low postrostral ridge on the carapace, fewer carpal articles of the left second pereopod and the small body size. The coloration in life is also different between the two. There is an indication of protandry in the new species, like other congeneric species.

A New Species

Lebbeus sokhobio sp. nov. is described from abyssal depths (3303−3366 m) in the Kuril Basin of the Sea of Okhotsk. The related congeners are deep-water dwellers with a very distant distribution and very similar morphology. The new species is separated by minor morphological features, such as the armature of the rostrum and telson, meral spinulation of ambulatory pereiopods and the shape of the pleonal pleurae. This species is the deepest dwelling representative of the genus Lebbeus and the family Thoridae. A list of records of caridean shrimps recorded from abyssal depths below 3000 m is given.

A new species of sponge without skeleton, Halisarca korotkovae sp. nov. is described from the Sea of Okhotsk. It differs from the other species of Halisarca by its different ecological conditions, as well as by its morphology and histology. The new species is characterized by its fulvous colour and by its big nucleolated, eosinophilic microgranular cells (18.7×9.5 to 10.8×7.1 μm) concentrated mainly in the ectosomal part of sponge in aggregates up to 40 μm in diameter.
