Adaptation To Deep-Sea Hydrothermal Vents: Some Molecular And Developmental Aspects, Florence Pradillon, Françoise Gaill
Journal of Marine Science and Technology
Alvinella pompejana is a polychaetous annelid inhabiting the surface of deep sea hydrothermal chimneys along the ridge of the east part of the Pacific ocean. The main characteristic of this emblematic species is its habitat, which is very aggressive considering its temperature. The exceptional thermotolerance of this species (up to 80°C) has been the subject of much controversy. This review is focused on the thermal adaptation of this worm regarding molecular data relative to its extracellular matrix and life history traits.

The oribatid mite, Archegozetes longisetosus, serves as a chelicerate model organism due to its relatively short life cycle and ease of laboratory culturing. It is a parthenogenetic species and all cultures recently used in different laboratories are descendants of a single female collected in 1993. While aspects of its developmental and functional biology have been published, knowledge of its reproductive rate and reproductive system is meager, and data on its life history are contradictory. Herein, we present the gross morphology of the reproductive system as obtained by SEM techniques and X-ray synchrotron microtomography, a new tool for studying mite anatomy. …
