Zoantharians are a group of cnidarians that are often found in association with marine invertebrates, including corals, in shallow and deep-sea environments. However, little is known about deep-sea zoantharian taxonomy, specificity and nature of their associations with their coral hosts. In this study, analyses of molecular data (mtDNA COI, 16S and 12S rDNA) coupled with ecological and morphological characteristics were used to examine zoantharian specimens associated with cold-water corals at depths between 110 and 800 m from seamounts and island slopes in the Azores region. The zoantharians examined were found living in association with stylasterids, antipatharians and octocorals. From the collected specimens, four new species were identified: (1)...

A preliminary review of zoanthid-hermit crab symbioses (Cnidaria; Zoantharia/Crustacea, Paguridea)
Provedor de dados: 16
Autores: Ates, R.M.L.
A preliminary review is presented of zoanthid-hermit crab symbioses reported in the literature. The records of Balss (1924) are included. Aspects of this type of symbiosis are discussed.

Platypodiella georgei spec. nov. (Brachyura: Xanthidae), a new crab from the island of St. Helena, South Atlantic Ocean, with notes on the genus Platypodiella Guinot, 1967
Provedor de dados: 16
Autores: Hartog, J.C. den; Türkay, M.
A new species of Platypodiella Guinot, 1967, from the island of St. Helena, P. georgei spec, nov., is described. This species was found associated with encrusting species of Palythoa Lamouroux, 1816 (Zoantharia). Ample evidence is presented that both the eastern Atlantic P. picta (A. Milne-Edwards, 1869) and the western Atlantic P. spectabilis (Herbst, 1794) also live habitually associated with encrusting species of Palythoa, rarely with other zoantharians. For each of the two East-Pacific members of the genus, P. rotundata (Stimpson, 1860) and P. gemmata (Rathbun, 1902), there is at least one rather detailed published record suggesting that these species too associate with Palythoa. Thus, this habit would seem to go for all five members of the genus. Data...

A note on an interesting association of the crab Platypodiella picta (A. Milne-Edwards 1869) and species of Zoantharia

In the framework of the CANCAP-Project, a long-term oceanographic collecting program performed by the Rijksmuseum van Natuurlijke Historie, extensive shore collections were made from 1976 onwards on most of the Macaronesian Islands. During the collecting trips, a very ornamental crab, Platypodi ella picta (A.MILNE EDWARDS, 1869) was found on three occasions by the senior author. In addition the species was collected on the coast of Senegal. In all cases it was found associated with species of Zoantharia.

Growth of the tropical zoanthid Palythoa caribaeorum (Cnidaria: Anthozoa) on reefs in northeastern Brazil
Provedor de dados: 42
Autores: SILVA,JANINE F.; GOMES,PAULA B.; SANTANA,ERIKA C.; SILVA,JOÃO M.; LIMA,ÉRICA P.; SANTOS,ANDRE M.M.; PÉREZ,CARLOS D.
In Brazilian reefs, zoanthids, especially Palythoa caribaeorum are fundamental for structuring the local benthic community. The objective of this study was to determine the growth rate of P. caribaeorum, and to assess the influence of the site (different beaches), season (dry and wet), location (intertidal or infralittoral zones), and human pressure associated with tourism. For one year we monitored the cover of P. caribaeorum in transects and focused on 20 colonies. We cut off a square (100 cm2) from the central part of the colony and monitored the bare area for four months in each season. The average growth rates varied from 0.015 and 0.021 cm.day-1. The rate was homogeneous in all localities, and there was no influence from colony site, location, or...
