Unique samples of deep-water sponges of Lake Baikal were collected between 120 and 1450 m depth and their taxonomy and bathymetric distribution were studied. Based on morphological studies with scanning electron microscopy (SEM) and molecular analyses (CO1, ITS) we describe a new species, Baikalospongia abyssalis sp. nov. Spicule morphology of this new species is similar to Palaeoephydatia sp., a species previously known only from fossils in Late Pliocene (3.2−2.8 mya) sediments. Other sponge samples collected were identified as Baikalospongia intermedia intermedia, B. intermedia profundalis, B. bacillifera, B. fungiformis, B. martinsoni and Swartschewskia papyracea, all from the family Lubomirskiidae. Sponge specimens with giant spicules, identified as B. fungiformis, were found at great depths. B.i. intermedia and B. i. profundalis are dominating species at great depth. Light is a limiting factor for distribution of Lubomirskia baicalensis, possibly due to its symbiosis with photosynthetic protists. The current study extends our knowledge on the distribution boundaries of Lubomirskiidae at great depths.

Two new nematode species of the genus Tobrilus Andrássy, 1959 from Lake Baikal are described and illustrated. The first species Tobrilus elginus sp. nov. was found in the littoral zone of Maloye More Bays. The second species Tobrilus juliae sp. nov. dwells on bodies of dead sponges Lubomirskia baicalensis (Pallas, 1776). Tobrilus elginus sp. nov. is most similar to T. amabilis Tsalolikhin, 1974 and T. bekmanae Tsalolikhin, 1975. In contrast to the first species it has a shorter body and spicules, longer gubernaculum and a shorter supplements row. Its body is shorter and thinner, tail and supplement row are shorter and the vulva is more posterior as compared to the second species. The body size of Tobrilus juliae sp. nov. is most similar to T. securus Gagarin & Naumova, 2011 and T. saprophagus Naumova & Gagarin, 2017. From the first of these species it differs by the thinner body, shorter tail, comparatively shorter outer labial setae and shorter spicules. It differs from the second species by a thinner body, shorter male tail and shorter labial setae.

The Food of the White-tailed Sea Eagle (Haliaeetus albicilla) at Lake Baikal, East Siberia A long-term study (1991-2001) of the food of White-tailed Sea Eagles in the Svâtoj Nos wetlands at Lake Baikal, Northeastern Russia, revealed that these eagles feed predominantly on water birds, mainly ducks. Anecdotal data from the Selenga Delta in Southeastern Lake Baikal indicate that White-tailed Sea Eagles generally prefer birds as their prey in the Lake Baikal area.

Unique Character

A new oligochaete worm, Stylodrilus aclotudi, has been reported from the southern part of Lake Baikal in East Siberia, Russia. The new species differs in extremely long tubular atria extending as far as segment XV, that is a unique character of the genus. This new fi nding increases the number of Stylodrilus species which are endemic to the lake up to 11, confi rming the existence of Baikal species flock.
