At deep-sea hydrothermal vents, deprived of light, most living communities are fueled by chemosynthetic microorganisms. These can form symbiotic associations with metazoan hosts, which then called holobionts. Among these, two endemic co-occurring shrimp the Mid-Atlantic Ridge (MAR), Rimicaris exoculata and chacei colonized dense diversified in their cephalothoracic cavity digestive system. Although both harbor similar communities, they exhibit widely different population densities,...
In deep-sea hydrothermal vent areas, deprived of light, most animals rely on chemosynthetic symbionts for their nutrition. These may be located cuticle, inside modified organs, or in specialized cells. Nonetheless, many these have an open and functional digestive tract. The shrimp Rimicaris exoculata is fueled mainly by its gill chamber symbionts, but also has a complete system with symbionts. are found the foregut midgut, roles remain unknown. We used genome-resolved metagenomics separate...

The shrimp Rimicaris exoculata and chacei are visually dominant fauna co-occurring at deep-sea hydrothermal sites of the Mid-Atlantic Ridge (MAR). Their co-existence was related to contrasted life-history traits, including differences in their diet reliance on chemoautotrophic symbionts adult stage. Both species colonized by diversified chemosynthetic symbiotic microbial communities cephalothoracic cavity. Symbiotic association with bacteria also evidenced digestive system, major lineages...
Abstract Most animal species have a singular developmental pathway and adult ecology, but plasticity is well-known in some such as honeybees where castes display profoundly different morphology ecology. An intriguing case the Atlantic deep-sea hydrothermal vent shrimp pair Rimicaris hybisae R. chacei that share dominant COI haplotypes could represent very recently diverging lineages or even morphs of same species. symbiont-reliant with hypertrophied head chamber (in Mid-Cayman Spreading...

Abstract Most animal species have a singular developmental pathway and adult ecology, but plasticity is well-known in some like honeybees where castes display profoundly different morphology ecology. An intriguing case the Atlantic deep-sea hydrothermal vent shrimp Rimicaris hybisae/chacei that share dominant COI haplotypes develops into either symbiont-reliant hybisae with hypertrophied head chamber (in Mid-Cayman Spreading Centre) or mixotrophic chacei narrow (on Mid-Atlantic Ridge). Here,...
