Oocyte size (in µm) distribution of two gastropod species from hydrothermal vent (Protolira valvatoides and Pseudorimula midatlantica) on different sites of the Montségur edifice (Lucky Strike vent field, Mid-Atlantic ridge). Data were collected thanks to histological analyses on several individuals of each species. Size structure of populations (shell length in mm) on different sites of the Montségur edifice.
Measurments were obtained from Image J softoware on pictures taken under microscope ans stereomicroscope
