Abstract

The shrimp Rimicaris exoculata is considered a primary consumer that dominates the fauna of most Mid-Atlantic Ridge hydrothermal ecosystems.The shrimps harbour in their gill chamber an important ectosymbiotic community of chemoautotrophic bacteria associated with iron oxide deposits.The settlement and development of this ectosymbiosis was investigated using microscopy techniques (light microscopy, LM; and scanning, transmission and environmental scanning electron microscopy: SEM and ESEM, respectively) for shrimps from 2 different vent fields (Rainbow, 36° 14.0' N and TAG, 26° 08.0' N).The results revealed a bacterial re-colonisation after each exuviation and a development of the bacterial community in 5 steps in relation to the moult stages, which were used as a reference time scale.In 287 shrimps from both vent fields, pre-ecdysial stages prevailed in the population, suggesting a short anecdysis and high moulting rate, probably to renew the ectosymbiosis.Comparisons with moult cycles of littoral shrimps suggest that the interval between successive exuviations in R. exoculata may be as short as 10 d.The colours of R. exoculata result from accumulation of iron oxide, which forms a bacteria-associated mineral crust in the gill chambers.The close correspondence between moult stages, the development of the ectosymbiont community and shrimp colours indicate that colour could be used to rapidly determine shrimp moult stages.

  • Every 10 days, the microbial community of the cephalothoracic cavity, but not the gut, is eliminated during the molt of the adult, and ectosymbionts rapidly re-colonize the host cephalothoracic cavity.

    “Interestingly, every 10 days, the microbial community of the cephalothoracic cavity, but not of the gut, is eliminated during the molt of the adult and ectosymbionts rapidly re-colonize the host cephalothoracic cavity (39, 40).”

    From Antimicrobial Peptides and Ectosymbiotic Relationships: Involvement of a Novel Type IIa Crustin in the Life Cycle of a Deep-Sea Vent Shrimp (2020) · cites this paper as [39]

    The Bacterial colonisation section says the gill-chamber bacterial community is renewed after each exuviation, with colonisation beginning within hours and a complete cover probably forming within two days. The Abstract and Moult cycle in life environment section describe the 10-day interval as a tentative estimate, not an established schedule. The paper does not establish that the gut microbial community remains intact during moulting; its references to the digestive tract concern feeding and ingested material. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
