A range extension for the spiny tailed skate, Bathyraja spinicauda is presented here, evidenced by an egg nursery observed atop a ridge on the Charlie Gibbs Fracture Zone along the Mid Atlantic Ridge. The species identification used an integrated taxonomic approach based on egg morphology and mtCOI barcoding of intact embryos. The egg nursery was mapped, and key environmental descriptors characterised: sedimentation, substrate type and predation risk. This egg nursery was recommended for classification as an essential fish habitat (EFH).

更深、更深、更远：观察绘制一个卵苗圃，深海多刺尾鳐Bathyraja spinicauda的范围和深度扩展，来自大西洋中脊的首次记录

此处展示了多刺尾鳐的范围扩展，Bathyraja spinicauda ，在沿大西洋中脊的查理吉布斯断裂带的山脊上观察到的卵苗圃证明了这一点。物种鉴定使用基于完整胚胎的卵形态和 mtCOI 条形码的综合分类方法。绘制了鸡蛋托儿所，并表征了关键的环境描述符：沉积物、基质类型和捕食风险。建议将此蛋苗圃归类为基本鱼类栖息地 (EFH)。
