Reproductive biology and population structure of Protolira valvatoides and Pseudorimula midatlantica

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.

对蒙塞古尔建筑物（幸运打击火山口场，中大西洋脊）不同位置的两种软体动物物种（原瓦氏螺和伪中脊螺）的卵母细胞大小（以微米为单位）分布及种群体型结构（以毫米计的壳长）进行了研究。数据收集得益于对每个物种多个个体的组织学分析。
