| Определитель обеспечивает возможность точного установления научного названия и систематического положения всех встречаемых в море организмов. Для каждой группы приводятся анатомо-морфологический обзор, определительные таблицы отрядов, семейств и родов с их краткими характеристиками и таблицы для определения видов. Рисунки приводятся для всех видов. Определитель выпущен в трех томах. В первый том включены простейшие, губки, кишечнополостные, черви, щупальцевые. Второй том охватывает всех свободноживущих представителей класса ракообразных, включая виды, населяющие опресненные солоноватоводные районы (с соленостью не менее 2-3%). Третий том посвящен группам свободноживущих беспозвоночных, не вошедшим в первые два тома, а именно: членистоногим (кроме... |

| The main aim of this study was to reveal reproduction barriers and potentially cryptic radiation within the very common and morphologically variable leech species - Erpobdella octoculata (L., 1758). The differences in reproductive success of the morphological forms were compared experimentally. The data based on the results of field sampling and analysis of ITS and COI sequences is also presented. The results of the analysis of DNA sequences clearly show lack of reproduction barriers between the analysed morphological forms. Subtle differences in DNA sequences between individuals, found with the use of the arbitrary primers method, seem to be related mainly to geographical distance between sub-populations. On the basis of these results, E. octoculata... |

| Does the medicinal leech Hirudo medicinalis feel well in the Netherlands (Hirudinea)? This paper provides information on the medicinal leech Hirudo medicinalis Linnaeus, 1758 particularly in The Netherlands. Although this species was common in The Netherlands in the 18th century, nowadays it is very rare. Most animals were found in waters on sandy soil (71%): dune pools (10%) and pleistocene sandy areas (61%), where it inhabits especially soft water moor and heathland pools. About 20% of the records originate from river areas, where the species can be found in breakthrough ponds and oxbow lakes. Only 9% of the records are from fen and clay areas. Records of single specimens are not proof of an established population, because these specimens could also... |

| Pomacea canaliculata is a common gastropod in freshwater habitats from Central and Northern Argentina, extending northwards into the Amazon basin. Several Platyhelminthes have been reported associated to P. canaliculata, sharing an intimate relationship with this gastropod host. The objectives of this study were to describe the symbiotic species assemblages associated to P. canaliculata in the study area, and to disclose differences among them. Samples were taken in three typical small streams and one artificial lentic lagoon, all connected with the Río de la Plata estuary. The 81.53% were infested with different symbiotic (sensu lato) species. Among the Platyhelminthes, the commensal Temnocephala iheringi Haswell, 1893 was highly prevalent in all samples,... |

| The presence of the sea leech, Stibarobdella macrothela (Schmarda, 1861) (Hirudinea, Piscicolidae), is marked in the south coast of Brazil, based on the single specimen with 67 mm (CT), collected in the intergill ventral region of a whaler shark, Carcharhinus brachyurus (Günther, 1870) (Chondrichtyes, Carcharhinidae), adult male with about 2 m (CT), being treated of the first registrations of S. macrothela in the Southwest Atlantic and the parasitic association with C. brachyurus. |
