  journal={Marine Biodiversity},
Scleractinian reef corals have been acknowledged as the most numerous host group for associated hydroids belonging to the genus Zanclea. To date, their geographical distribution is known to include several Indo-Pacific regions. During the Statia Marine Biodiversity Expedition to St. Eustatius (Lesser Antilles, Dutch Caribbean), the Zanclea-coral association was observed for the first time for the Caribbean Sea as well as for the Atlantic Ocean. Our findings confirm that the biodiversity… 
First Atlantic record of the green alga Parvocaulis exiguus from St. Eustatius, Dutch Caribbean
This report presents the first record of Parvocaulis exiguus from the Atlantic Ocean, collected at 18 m depth from rocky substrata surrounded by seagrass off the Dutch Windward Caribbean island St. Eustatius.
New host records of scleractinian-Zanclea symbiosis from Fiji
Scleractinian corals are the host group with the greatest number of species associated with hydroids in the genus Zanclea. There are 34 nominal species and 31 genera of scleractinians reported as
A cryptic species in the Pteroclava krempfi species complex (Hydrozoa, Cladocorynidae) revealed in the Caribbean
Three divergent molecular clades represent distinct cryptic taxa within the P. krempfi species complex, in which the main interspecific difference consists of their host families.
Genetic diversity of the Acropora-associated hydrozoans: new insight from the Red Sea
This study investigated the morphology and genetic diversity of Acropora-associated Zanclea specimens collected in previous studies in Egypt and Israel, as well as new samples collected in Saudi Arabia, and identified a previously unknown cryptic species of Acrostora- associated hydroid, here named Zancrea gallii IIa, following a recently proposed molecular nomenclature.
Habitat preferences of the Pteroclava krempfi-alcyonaceans symbiosis: inner vs outer coral reefs
Herein, we provide observation on the ecological relationships between the hydrozoan species Pteroclava krempfi and three alcyonacean genera: Lobophytum, Sarcophyton and Sinularia from protected and
Symbiont footprints highlight the diversity of scleractinian‐associated Zanclea hydrozoans (Cnidaria, Hydrozoa)
This work further explores the morpho‐diversity of three genetic lineages, namely Zanclea associated with the coral genera Goniastrea, Porites and Pavona, and provides a complete classical characterisation of the polyp and medusa stage of each clade.
Hydroid diversity of Eilat Bay with the description of a new Zanclea species
The present investigation provides new information about diversity in the Red Sea, and in particular in Eilat Bay, which has significance for Mediterranean and Red Sea biodiversity conservation and the consequent possible increase in the introduction of nonindigenous species in both directions.
Biodiversity of Reef-Building, Scleractinian Corals
Zooxanthellate scleractinian corals are moderately well-known for shallow reef habitats, but not for mesophotic depths (>30 m) that are relatively difficult to access. Mesophotic habitats are
Diversity of estuarine and marine hydroids (Cnidaria, Hydrozoa) from subtropical ecosystems of Brazil
The subtropical coastal waters of Brazil have been surveyed regarding their hydroid fauna since 1941. However, a comprehensive compilation of all hydroid records with detailed information has not yet
Monitoring and assessing a 2-year outbreak of the corallivorous seastar Acanthaster planci in Ari Atoll, Republic of Maldives
The size structure analysis revealed a multimodal distribution dominated by individuals between 20 and 30 cm, suggesting that the outbreak may have resulted from a few nearby mass spawning events, and the electivity index showed a preference for corals of the genera Favites and Pavona.


First record of coral-associated Zanclea (Hydrozoa, Zancleidae) from the Red Sea
The first evidence of such Zanclea-coral associations from the Red Sea is reported, extending their known geographical distributions and host range.

The new species of Zanclea sango sp. nov. is described from Okinawajima Island, Ryukyu Archipelago, south-western Japan. The new hydrozoan species is associated with at least three scleractinian
Molecular Evidence Shows Low Species Diversity of Coral-Associated Hydroids in Acropora Corals
A novel symbiosis between scleractinians and hydroids (Zanclea spp.) was recently discovered using taxonomic approaches for hydroid species identification, suggesting that a cosmopolitan and probably genus-specific association occurs between ZancleA hydroids and their coral hosts.
Mushroom corals as newly recorded hosts of the hydrozoan symbiont Zanclea sp.
A survey in the Maldives aimed at the discovery of Zanclea–Fungiidae associations found 10 new host species were discovered and the number of recorded coral host genera increased from 17 to 24, taking recent taxonomic revisions into account.
A survey of Zanclea, Halocoryne and Zanclella (Cnidaria, Hydrozoa, Anthomedusae, Zancleidae) with description of new species
The architecture of the newly released medusae of Zanclella is exceptional due to a sharp compression of the exumbrella and of the presence of just two radial canals, and a phylogenetic scenario is suggested, in spite of the inconsistencies in the rates of change in the two main stages of the cycle.
A novel reef coral symbiosis
A novel symbiosis between a newly described hydrozoan (Zanclea margaritae sp. nov.) and the reef building coral Acropora muricata is described, with the hydrozoans hydrorhiza ramifying throughout the coral tissues with no evidence of isolation or activation of the immune systems of the host.
