This study deals with comparison of morphology and in situ behaviour of three Alvinocarididae species from the Snake Pit hydrothermal area (mid-Atlantic ridge), explored during the Hydrosnake cruise (1988). Spatial distribution on the site is described and illustrated for the three species. Rimicaris exoculara highly predominates. Modifications, apparently more morphological than functional, allowed adaptation to an environment characterised by extreme physico-chemical conditions and richness in bacteria. This species has developed a culture of bacteria on its mouthparts and under the carapace to complement nutrient input drawn from bacterial production from the surface of active chimneys. Rimicaris exoculata aggregates on active diffusers and affect the... |
