: The process of insemination and fertilization in the nematode family Oncholaimidae is of interest because females of many species have extremely unusual sperm storage organ called “Demanian system”. The mature spermatozoa from the main duct of the Demanian system of the free-living marine nematode Admirandus multicavus (Enoplida: Oncholaimidae) were studied by the transmission electron microscopy. The main duct is an epithelial tube with thick basal lamina. The dilated part of the duct is occupied by cluster of densely packed spermatozoa 7–8 µm in size, while the narrow part contains occasional strongly elongated sperm cells. The centre of spermatozoa is occupied by a nucleus with poorly condensed chromatin surrounded by a distinct nuclear envelope, the presence of which confirms isolation of enoplids from all other clades of nematodes. The prevalent components of sperm cytoplasm are ‘membranous organelles’ (MO) which resemble strongly elongated thread-like osmiophilic cisternae densely packed into bundles. Small numerous mitochondria are interspersed between bundles of MOs. Spermatozoa form pseudopods that reflect putative amoeboid cell motility. Amorphous nucleus, thread-like MOs, and numerous minute mitochondria are likely to represent preadaptation to squeezing through the narrow tubular communications of the Demanian system. Present observations of A. multicavus support basic characters of the oncholaimid sperm pattern previously described in another oncholaimid

: A prototroch is a characteristic larval idiosyncratic structure conserved among Lophotrochozoa. It appears as the first prominent structure during embryogenesis, serves for swimming and filter-feeding, then degenerates or is modified after metamorpho-sis. Using cutting-edge confocal laser scanning microscopy, we investigated the detailed structure of the Dimorphilus gyrociliatus prototroch area and demonstrated that it is much more complex than previously thought. The first row of ciliated cells differentiates at the trochophore stage. By juvenile stage, three rows of ciliated cells are located in the prostomium region: an anterior row of cells with long (14–16 µm) cilia, an intermediate row of cells with short (3–4 µm) cilia, and a posterior row of cells with cilia of middle length (9– 10 µm). Each ciliated row consists of two bands of cilia-bearing cells. We suggest that the anterior row represents what is commonly considered a prototroch. At the same time, the intermediate row is considered homologous to the adoral ciliary zone, and the posterior row is considered homologous to the metatroch. Older individuals retain this ciliated apparatus until the last days of their life. With age, cilia in prototroch and metatroch become twice shorter; and the prototroch gets wider, at the end consisting of four lines of ciliated cells. inhibition of muscle contraction, the freshly hatched juveniles maintain the ability to uptake food particles. These findings confirm earlier observations showing that D. gyrociliatus uses its complex ciliated apparatus in the prostomial region for filter-feeding in addition to bulbus-scrabbing. Thus, we clarified the organization of the ciliary bands of D. gyrociliatus located in the prostomial region, documented their persistence during ontogenesis, as well as confirmed the participation of the ciliary apparatus in active food intake. These data support the paedomorphic character demonstrated for Dimorphilus gyrociliatus .

: Brachiopods are marine invertebrates with a pelago-benthic life cycle. The life cycle and structure of planktonic stages vary among brachiopod taxa. Many rhynchonelliform brachiopods, including those in the order Rhynchonellida, brood three-lobed larvae (i.e., the cephalulae) in the mantle cavity. However, no cephalulae were found in the mantle cavity of the rhynchonellid Hemithiris psittacea (Gmelin, 1791) from the White Sea. In this research, artificial insemination and induced spawning were used to study the ontogeny of H. psittacea from the White Sea Biological Station of Moscow State University (Kandalak-shskii Bay of the White Sea). After fertilization, a thick egg envelope forms around the zygote and adheres to the substrate. Cleavage, gastrulation, and formation of the three-lobed cephalula occur within the egg envelope. A worm-like competent cephalula hatches from the egg envelope and swims along the substrate rather than in the water column. The cephalula of H. psittacea differs in structure from the terebratulid larva, which actively swims in the water column. In contrast to terebratulid larva, the cephalula of H. psittacea lacks the eyespots and has shorter and less abundant setae. Development of H. psittacea from the White Sea proceeds in the external environment rather in the lophophore of the female. These results are inconsistent with the published data on H. psittacea from the San Juan Channel (Washington, USA), whose larvae develop outside the egg envelope in the lophophore of the female. A possible explanation is that Hemithiris from the San Juan Channel and from the White Sea represent separate species. The current report for H. psittacea from the White Sea is the first to describe embryonization of larval development for a rhynchonelliform.
:腕足类动物是海洋无脊椎动物，其生命周期为上底栖动物。不同腕足动物类群浮游阶段的生命周期和结构各不相同。许多铃足目腕足动物，包括铃足目，在地幔腔中孵化三叶幼虫(即头足类)。然而，在白海的rhynchonellid Hemithiris psittacea (Gmelin, 1791)的地幔腔中未发现cephalulae。本研究采用人工授精和诱导产卵的方法，对莫斯科国立大学白海生物站(白海Kandalak-shskii湾)的psittacea进行了个体发育研究。受精后，受精卵周围形成一层厚厚的卵包膜，并附着在基质上。卵裂、原肠胚形成和三裂头的形成发生在卵包膜内。一个蠕虫状的有能力的头虫从卵囊中孵化出来，沿着基质而不是在水柱中游动。棘球绦虫的头在结构上不同于在水柱中活跃游动的非脊椎动物幼虫。与terebrater目幼虫相比，H. psittacea的头状体缺少眼点，且刚毛较短且较少。来自白海的psittacea的发育是在外部环境中进行的，而不是在雌性的lophore中进行的。这些结果与美国圣胡安海峡(San Juan Channel, Washington, USA)已发表的关于psittacea的资料不一致，因为psittacea的幼虫在雌鸟的卵膜外发育。一种可能的解释是，来自圣胡安海峡和来自白海的Hemithiris代表不同的物种。目前关于白海的psittacea的报告是第一个描述纹状体幼虫发育的胚胎化。

: Sponges differ from the majority of multicellular animals by lack of specialized neural cells. Although sponge genomes show the toolkits for metabolism of some neuroactive substances, only few genes of monoamines metabolism were found. We studied larvae of the freshwater sponge Eunapius fragilis to analyze the immunoreaction to one of the monoamines – dopamine (DA). We found dopamine-like immunoreactivity in structures located under every flagellum in the larval epithelial cells. Double labeling with anti-DA and anti-58K Golgi protein antibodies, confocal microscopy with improved signal-to-noise ratio and super-resolution (Airyscan), and ultrastructural electron microscopy analysis revealed that the DA-like-immunopositive structures are closely associated with the Golgi apparatus. A similar pattern of immunolabeling was reported in the blastulae of sea urchins, whose ciliary activity is known to be affected by monoamines. Our finding of DA-like immunoreactive structures in sponge ciliated cells provide morphological basis for considering monoamines as potential intracellular regulators of flagellar/ciliary activity.
