Open AccessVariation in species and functional composition of octocorals and zoantharians across a tropical to temperate environmental gradient in the Indo-Pacific
Global warming causes functional shifts and reorganisation in marine communities through range shifts to high-latitude reefs and cnidarian bleaching mortality in the tropics. Such changes threaten the integrit...

Unlocking the jar: revealing gastric content in Ceriantharia (Cnidaria, Anthozoa) through whole-genome shotgun sequencing
This study focuses on the analyses of the gastral cavity contents of two species of Ceriantharia, namely Isarachnanthus nocturnus Hartog, 1977, collected in São Sebastião, Brazil, and Pachycerianthus magnus Nakam...

Spawn release of a Sclerophytum soft coral species in Okinawa Island, Japan
We report the first documentation of in situ release of reproductive materials by female colonies of a soft coral, in this case Sclerophytum cf. heterospiculatum, from the subtropical island of Okinawa, Japan. Sp...

Phylogenomics of Palythoa (Hexacorallia: Zoantharia): probing species boundaries in a globally distributed genus
Zoantharians (Cnidaria: Hexacorallia: Zoantharia) of the genus Palythoa are ubiquitous species that occupy reef habitats in every tropical ocean. Disagreements among classifications based on morphology, reproduct...

Open AccessEvolution and biogeography of the Zanclea-Scleractinia symbiosis
Scleractinian corals provide habitats for a broad variety of cryptofauna, which in turn may contribute to the overall functioning of coral symbiomes. Among these invertebrates, hydrozoans belonging to the genus Z...

Global diversity and distribution of Lamippidae copepods symbiotic on Octocorallia
This paper reviews all currently known records of copepod crustaceans of the family Lamippidae (Cyclopoida). The lamippids are highly modified endosymbionts found only on octocorals in the channels of mesoglea...

Article
Palaeoclimate ocean conditions shaped the evolution of corals and their skeletons through deep time
Identifying how past environmental conditions shaped the evolution of corals and their skeletal traits provides a framework for predicting their persistence and that of their non-calcifying relatives under imp...

Article
Open AccessFunctional diversity of reef molluscs along a tropical-to-temperate gradient
Global warming is leading to range shifts of marine species, threatening the structure and functioning of ecological communities and human populations that rely on them. The largest changes are seen in biogeog...

Article
Crinoid diversity and their symbiotic communities at Bangka Island (North Sulawesi, Indonesia)
Members of the order Comatulida (Echinodermata: Crinoidea) are widely distributed on Indo-Pacific reefs, where they host a highly diverse and understudied cryptofauna, which makes them a potential source of hi...

A species complex within the red-reticulate Goniobranchus Pease, 1866 (Nudibranchia: Doridina: Chromodorididae)
The taxonomy and diversity of chromodorid nudibranchs (Mollusca: Gastropoda: Nudibranchia) are relatively well-studied, although molecular analyses have only been applied to test few species-level groups. With...

Article
Diversity of zoantharian species and their symbionts from the Macaronesian and Cape Verde ecoregions demonstrates their widespread distribution in the Atlantic Ocean
Zooxanthellate zoantharians (Cnidaria: Anthozoa) are commonly found in tropical and subtropical marine regions around the world. However, due to the low genetic variability of commonly used DNA markers combine...

The distribution of reef-dwelling Waminoa flatworms in bays and on capes of Okinawa Island
Waminoa spp. are acoel worms living on the surface of anthozoans. Despite being potential parasites, there is still not much information available regarding the genus’ distribution or host selectivity. The aim of...

Description of the juvenile form of the sea cucumber Thelenota anax H. L. Clark, 1921
Our knowledge of the ecology and habitat of juveniles of many sea cucumber species is limited, due to their cryptic habitats and differing color and shape from adults. In the present study, a juvenile specimen...

First records of zooxanthellate Zoanthus (Anthozoa: Hexacorallia: Zoantharia) from Korea and Japan (East) Sea
This report presents the first records of the zooxanthellate species Zoanthus sansibaricus (Anthozoa: Hexacorallia: Zoantharia: Zoanthidae) from Jeju Island, Korea, in the East China Sea, and from Dogo-jima Islan...

Open AccessAmphioxus mouth after dorso-ventral inversion
Deuterostomes (animals with ‘secondary mouths’) are generally accepted to develop the mouth independently of the blastopore. However, it remains largely unknown whether mouths are homologous among all deuteros...

Chapter
Ceriantharia in Current Systematics: Life Cycles, Morphology and Genetics
The systematics of the class Anthozoa has been built-up by a number of authors with different approaches. However, despite all efforts the evolutionary position of the tube-dwelling anemones (subclass/order Ce...

Chemoattraction of the pearlfish Encheliophis vermicularis to the sea cucumber Holothuria leucospilota
The specificity of the relationship between Indo-Pacific pearlfish (family Carapidae) and their hosts, the sea cucumbers (Holothuridae), was examined in Okinawa, Japan. While some species of pearlfishes lived ...

Eight polymorphic microsatellite loci for the Indo-Pacific-wide zoanthid, Zoanthus sansibaricus
Next generation sequencing allows rapid development of genetic markers for investigating the ecology and evolution of non-model organisms. In the present study we employed 454 sequencing and high through-put s...
