We herein present the results of a survey which assessed the benthic fauna from subtidal to continental shelf depth in the Shirahama area from 2012 to 2016. Our research resulted in the identification of 132 species from 75 families in seven phyla, Cnidaria, Annelida, Tardigrada, Arthropoda, Mollusca, Echinodermata and Chordata. This includes 24 newly recorded species to Shirahama. Two species were also new records for Japanese waters. Furthermore, six undescribed species and five potentially undescribed species were recorded. We provide a selection of relevant photos for future taxonomic studies and monitoring of environmental changes.

A new species of heteronemertean with branched proboscis, Gorgonorhynchus albocinctus sp. nov., is described based on the external feature and DNA sequences from a specimen collected subtidally among coral rubbles at a depth of about 6 m in a reef area around Taketomi Island in the Yaeyama Islands, southwestern Japan. It can be classified in the genus because the mode of proboscis branching is dichotomous, rather than alternating laterally. From the two known congeners G. repens Dakin and Fordham, 1931 and G. bermudensis Wheeler, 1940, the new species can be differentiated by having a brown body colour with a white band near the tip of the head. The new species is placed in a molecular phylogenetic context with a maximum-likelihood analysis using the nuclear 18S rRNA and 28S RNA genes, as well as the mitochondrial cytochrome c oxidase subunit I gene, together with 20 species of heteronemerteans, for which those sequences were available in the public databases. The results indicate that G. albocinctus is closely related to Cerebratulus leucopsis (Coe, 1901), a species that is supposed to have a non-branched proboscis.

This is the first comprehensive list of sharks, batoids (rays and skates) chimaeras recorded from the waters of Russia and adjacent territories. This includes scientific names, common names (English, Russian in Latin transcription, Japanese and Czech), taxonomic comments, if necessary, distribution, synonymy and conservation status. From Russia the border areas, 40 species of sharks, 59 species of batoids and 7 species of chimeras that belong to the two classes (Elasmobranchii and Holocephali), 11 orders, 29 families, 5 subfamilies and 54 genera have been recorded over the last hundred years.
