Hydrothermal vent ecosystems are expected to harbor numerous meiobenthic animals; however, few studies have examined the species composition, abundance, and distribution of harpac…

Fenestrulina malusii (Audouin & Savigny), the type species of Fenestrulina Jullien, is among the most widely reported bryozoans globally. Following the loss of the original type m…

Two species belonging to the family Laophontidae Scott T., 1905 were identified among harpacticoid copepods collected from marine plastic debris (MPD) stranded along the Korean co…

A colonial ascidian of the genus Distaplia caused a mass mortality of the pen shell Atrina maura (Sowerby, 1835) during June 2016 in the southwest of the Gulf of California (Mexic…

The Mediterranean specimens of the genus Microporella collected from shallow water habitats during several surveys and cruises undertaken mostly off the Italian coast are revised.…

The reproductive and developmental characteristics of the nereidid polychaete, Neanthes glandicincta Southern, 1921, commonly recorded in tropical estuaries in the Indo-West Pacif…

Using the nudibranch genus Amphorina as a model, ongoing speciation is demonstrated, as well as how periodic-like patterns in colouration can be included in an integrated method o…

A new species of Leucosoleniidae, Leucosolenia qingdaoensis sp. nov., is described. This new species was collected in a scallop-breeding pond from the Yellow Sea and preserved in …

This study is the first inventory of ascidians from shallow waters (0–25 m) of coastal and reef habitats in the southern Gulf of Mexico where ascidian diversity is poorly known. S…

Hard bottom communities of the Reloncaví Estuary and adjacent areas, Region de los Lagos, Chile (42°S), were studied between 2008 and 2011. All hard substrates between the lower i…

Paratetilla bacca (Selenka, 1867) and Cinachyrella australiensis (Carter, 1886) occur in a broad range of marine environments and are allegedly widely distributed species in the I…

Ptilohyale explorator (formerly Parhyale explorator), described by Arresti (1989), can be considered to be a synonym of west-Atlantic Ptilohyale littoralis (Stimpson, 1853), based…

Sponges are key components of the benthic assemblages and play an important functional role in many ecosystems, especially in coral reefs. The Indonesian coral reefs, located with…

During the implementation of a large project aimed to investigate the benthic community structures of the Sea of Marmara, specimens of the invasive ascidian species Styela clava w…

A new sponge species (Demospongiae: Agelasida: Agelasidae) is described from the eastern coast of Unguja Island in the Zanzibar Archipelago. Agelas sansibarica sp. n. is compared …

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…

Ocean warming and acidification are major drivers of change in marine ecosystems, with particularly strong impacts on low-mobility benthic organisms. Despite their ecological impo…

The sub-Antarctic region is notable for its high macroalgal diversity. Although a number of studies have documented the species richness of macroalgae along the Chilean sub-Antarc…

Climate change is profoundly altering marine ecosystems through ocean warming and acidification. These stressors are especially pronounced in the Mediterranean Sea, a climate chan…

Over the past 50 years, the oceans have absorbed over 90% of global warming heat, leading to warming, acidification and declining oxygen levels that are disrupting marine ecosyste…

Three new chitons are reported from distinct and underexplored marine habitats: Ferreiraella populi sp. nov. from deep-sea sunken wood off Japan in the western Pacific, Notoplax m…

Biological invasions are considered one of the main threats for biodiversity. In the last decades, more than 60 macroalgae have been introduced in the Mediterranean Sea, causing s…

Shellfish mariculture, particularly of oysters, poses a significant risk for the introduction of non-native species into marine ecosystems. This study investigates the diversity o…

Invasions by non-indigenous species (NIS) are among the major problems that coastal ecosystems are facing globally and are driven by anthropogenic activities, such as internationa…

This paper describes a new species of Halamphora – Halamphora lombokensis sp. nov. and records for the first time Halamphora banzuensis for the coasts of Indonesia. The study util…

Indonesia is listed as a region with high marine biodiversity, especially when considering the three large tropical ecosystems: seagrass beds, mangroves and coral reefs. It is lik…
