The present study presents a revision of the genus Ceriantheomorphe Carlgren, 1931, including redescriptions of the two presently recognized species, Ceriantheomorphe ambonensis (…

Despite the ubiquity of sea anemones (Cnidaria: Actiniaria) in tropical ecosystems, our understanding of their biodiversity and taxonomy is limited. Here we re-establish the ident…

Associations of various invertebrate species with bryozoans and sponges are a well-known marine phenomenon but such epizooic communities are far less diverse in freshwater environ…

Three new deep-water species of Bebryce from Japan are described and depicted using Scanning Electron Microscopy: B. otsuchiensis sp. n., B. rotunda sp. n., and B. satsumaensis sp…

The status of Indo-Pacific Briareum species (Cnidaria, Octocorallia, Briareidae) is reviewed by presenting their sclerite features and habitus descriptions. Following the re-exami…

A new family, genus and species of cubozoan box jellyfish belonging to the order Chirodropida is reported from the eastern Japan. Meteorona kishinouyei gen. et sp. n. possesses th…

The present study deals with the presence of Diopatra marocensis in the eastern Mediterranean. This species is small-sized and inhabited muddy bottom near the opening of rivers or…

Research on sea spiders in China is relatively scarce and there is a severe shortage of regional basic data. In earlier studies, there was a lack of attention given to this small …

The genus Allostoma von Beneden, 1861 (Pseudostomidae Graff, 1904) consists of generally small, often conspicuously colored species. These organisms are typically found on hard bo…

The Mediterranean Region is considered one of the areas most exposed to climate warming, with artificial lakes and coastal lagoons representing particularly vulnerable ecosystems,…

A central aspect of ecology is the understanding of how environmental factors influence species distribution, population structure, and dynamics, ultimately highlighting species’ …

Invasive species pose threats to either human health or inflict ecological and/or economic damage. The silver-cheeked toadfish (Lagocephalus sceleratus), a Lessepsian species, is …

The gorgoniid Eugorgia is exclusively an eastern Pacific genus. It has a wide geographic and bathymetric range of distribution, found from California to Perú and extends down to 6…

Seven sea anemone species from coral reefs in the southern Gulf of Mexico are taxonomically diagnosed and images from living specimens including external and internal features, an…

A taxonomic assessment of four species of octocorals from the northeastern Pacific Ocean (British Columbia to California) is provided. Included here are a new species of clavulari…
