TL;DR: In this paper, the main physical and chemical characteristics of the vent habitat were studied by discrete sampling, in situ analysis and sediment trap moorings, showing that the vent fauna is distributed along a variable band where the vent fluids and seawater mix, with R. exoculata living in most concentrated areas and Bathymodiolus azoricus in the most diluted zones.

TL;DR: The geological setting and vent fluid composition of the fields are considered together with their community composition to tentatively ascertain the order of a hierarchy between dispersal and environmental control, suggesting faunal islands that have distinct composition and habitat requirements.

TL;DR: La specialisation trophique, qui se traduit par des transformations graduelles des pieces buccales d'Alvinocaris a Rimicaris en passant par Chorocaris, s'accompagne du developpement progressif d'un organe oculaire dont la fonction exacte demeure non-elucidee.

TL;DR: Fatty acid biomarker analysis coupled with gas chromatography-isotope ratio mass spectrometry was used to confirm the presence of methanotrophic and thiotrophic bacterial endosymbionts in the tissues of a hydrothermal vent mussel collected from the Menez Gwen vent field on the mid-Atlantic ridge.

TL;DR: Molecular data (18S rRNA) gene confirm the clear difference between anomuran families, placing the new tax a closer to the families Chirostylidae, Galatheidae and Porcellanidae than t o Aeglidae.
