The purpose of the research is studying the morphology of larvae of Trematoda  Monorchiidae of the genus Paratimonia and establishing possible causes of their accelerated morphogenesis.Materials and methods. The material for this study was trematode larvae (metacercariae) from 283 specimens of gastropods Hydrobia acuta that we collected in March 2012 at the estuary of the River Chernaya (Sevastopol, the Black Sea, 44°27′49″ N 33°51′37″ E). The gastropods were studied for helminths using the compression method. Some of specimens of the found trematodes were studied alive and others were fixed in 70% ethyl alcohol and then stained with acetocarmine according to the standard method. The morphological features of metacercaria were studied on live larvae.Results and discussion. During helminthological research of gastropods Hydrobia, we recorded metacercariae of the family Monorchiidae. Non-encysted metacercariae were located freely in the host’s body cavity.

First Time

We studied for the first time luminescence characteristics of the some micromycetes, isolated from the bottom sediments of the Black sea from the 27 m depth. Luminescence parameters were registered at laboratory complex “Svet” using mechanical and chemical stimulations. Fungi cultures of genera Acremonium, Aspergillus, Penicillium were isolated on ChDA medium which served as control. Culture of Penicillium commune gave no light emission with any kind of stimulation. Culture of Acremonium sp. has shown luminescence in the blue – green field of spectrum. Using chemical stimulation by fresh water we registered signals with luminescence energy (to 3.24 ± 0.11)•108 quantum•cm2 and duration up to 4.42 s, which 3 times exceeded analogous magnitudes in a group, stimulated by sea water (p < 0.05). Under chemical stimulation by ethyl alcohol fungi culture luminescence was not observed. Culture of Aspergillus fumigatus possessed the most expressed properties of luminescence. Stimulation by fresh water culture emission with energy of (3.35 ± 0.11)•108 quantum•cm2 and duration up to 4.96 s. Action of ethyl alcohol to culture also stimulated signals, but intensity of light emission was 3–4 times lower than under mechanical stimulation. For sure the given studies will permit not only to evaluate contribution of marine fungi into general bioluminescence of the sea, but as well to determine places of accumulation of opportunistic species in the sea.

Hans Lissmann overcame extraordinary difficulties to become one of the pioneers of experiments on animal locomotion and the discoverer of the electric sense of fishes. The Russian Empire He was born on 30 April 1909 at Nikolayev, a Black Sea port near Odessa. Most of what we know of his early life comes from two typewritten memoirs, written in 1944 when he was interned. He was the younger of the two sons of German parents, Robert Lissmann, an exporter of grain, and his wife Ebba. A photograph taken in 1913 or 1914 shows a prosperous family formally posed with the boys dressed immaculately and impractically, entirely in white. Until Hans was five the family lived in Nikolayev and in Novorossiysk, another port on the northern shore of the Black Sea. He spoke Russian with his parents and French with his grandparents. Then, after the outbreak of the First World War in 1914, the family was sent to Kargala, a village near Orenburg on the edge of the Urals, 1100 miles north-east of Nikolayev. There they were interned as aliens among a population of Tartars, Bashkirs and Kirghis. Hans learned some Tartar, and was also taught German. Drawings that he made there show a village of log buildings inhabited by men in turbans, and a rider on a Bactrian camel. Their mother taught the boys arithmetic and languages, and arranged for them to be introduced to biology by an interned zoologist and a botanist who took them into the surrounding countryside on summer afternoons. She supported the family by teaching in the village school when her husband was arrested and taken away for several months. The Russian Revolution came, and Kargala was captured and recaptured several times by the Reds and Whites.

Two new species of the family Microlaimidae Micoletzky, 1922 are described and illustrated from the Black Sea. Aponema pontica sp. n. is morphologically closest to A. torosum in the shape of the body and spicules, size of amphids, but differs in having small and triangular cardia, absence of constriction in head region, shape of gubernaculum apophyses, rounded and weakly sclerotised lumen of pharyngeal bulb and longer spicules. Microlaimus paraglobiceps sp. n. morphologically resembles M. globiceps de Man, 1880 in the shape of the body, structure of the male sexual organs and presence of precloacal pore, but the main difference is a shorter body, cuticle finely annulated all over the body and absence of sexual dimorphism in the size of amphideal fovea.

The description of the record of a bat found in the period of autumn migrations on a ship on the Black Sea is given. The bat was found on the captain's bridge, and the sailors stated that the bat landed on the ship during flight and was not brought onto the board. The location of the discovery is on a raid near Sevastopol, 9 October 2013, within 10 miles from shore. Morphological features of the specimen are as follows: forearm length is about 33.1 mm, general colouration is brown with a narrow (1–2 mm) whitish stripe along the free edge of the wing up to the hind foot. The morphology of the earlobes, tragus, rhinarium, and post calcarial lobe are typical of P. pipistrellus/pygmaeus/nathusii. The morphology of the rhinarium (without the middle bulge between the nostrils) and the genitals is similar to those in P. nathusii. The most distinctive feature of the specimen is the presence of a white edging on the wings, which is usually common for Asian P. p. bactrianus, but, to some extent, also occurs among southern P. nathusii.

Devonian Age

The Bivalvia family has been traced back to the beginning of the Paleosoic Era (The Devonian age) and have survived to this day, with very small changes. While more common in the Mediterranean, the Black Sea has been penetrated by representatives of the family, most frequently along the coastal area. Representatives of the Mytilus genus, mussels are very common in the seas and oceans of the world. Mytilus Galloprovincialis Lamarck has long been considered as being only a variety of Mytilus edulis Linne. Anatomical studies have shown that there are sufficient differences in order to accurately distinguish the two species. This paper presents a characterization of the Mytilus galloprovincialis mussel, which is a valuable resource existing in the Black Sea ecosystem.

Abstract The article describes occurrence and distribution of Cryptocotyle trematodes in fish in the waters of the Dnipro-Buh estuary and the Black Sea in Mykolaiv and Odesa Region. Study was conducted in 2015-2016. Two trematode species were found in natural waters of these regions: Cryptocotyle cancavum Crepli, 1825 and Cryptocotyle jejuna Nicoll, 1907. Th e latter species has not been previously registered in this region in southern Ukraine. Varying intensity of infection with Cryptocotyle metacercariae was observed in fish of Gobiidae family: Mesogobius batrachocephalus Pallas, 1814, Neogobius melanostomum Pallas, 1814, N. fluviatialis Pallas, 1814. Th e most affected species was N. melanostomum, with the prevalence of infection 59.2 %. Less infected were N. fluviatialis and M. batrachocephalus, with the prevalence of infection 30.4 % and 17 % respectively. The intensity of infection was the highest in N. melanostomum - 211 metacercariae per fish, followed by N. fluviatialis and M. batrachocephalu - 124 and 89 metacercariae respectively. Cryptocotyle was the most prevalent in the Dnipro-Buh estuary (cape Adzhigol, Mykolaiv Region) and much less prevalent in the waters of the Black Sea in Mykolaiv and Odesa Regions. Mean prevalence of infection was 31.4 %.

The foliicolous species Bacidia colchica Vězda was described from the eastern coast of the Black Sea (Vězda 1979, 1983) and is also known from SW France (Sérusiaux 1989; Sérusiaux et al. 2002) and S Italy (Puntillo 2000; Puntillo et al. 2000). However, its morphological features, such as the structure of the exciple, morphology of the paraphyses and ascus type, do not fit the current concept of Bacidia De Not. (Ekman 1996, 2001) but place this taxon in the Pilocarpaceae. The current circumscription of Pilocarpaceae is still under discussion, as well as the concept of some genera at present included in this family (Sérusiaux 1993; Lücking et al. 1994; Kalb et al. 2000; Lücking et al. 2001a; Sérusiaux et al. 2002; Andersen & Ekman 2005). In particular, the position of B. colchica should be in Fellhanera Vězda (Vězda 1986; Lücking et al. 1994; Sérusiaux 1996; Lücking 1997). Although several recent works have dealt with the European species of the genus Fellhanera (Sérusiaux 1996; Aptroot et al. 1998; Sparrius & Aptroot 2000; Sérusiaux et al. 2001; Sparrius 2002; Spier et al. 2002), none of them included B. colchica, despite some of the papers considering foliicolous taxa.
