The larvae of the deep-sea pandalid shrimp Doflein, 1902 were successfully reared in the laboratory for the first time. The larvae reached the eighth zoeal stage in 36 days, both of which are longest records for the genus. Early larval stages of bear the general characters of pandalid shrimps and differ from the other two species of with larval morphology known in the number of spines on the anteroventral margin of carapace, number of tubercles on antennule, endopod segmentation in antenna, and third maxilliped setation. Although members in are often separated into species groups, members of the same species group do not necessarily have similar early larval morphology. Since the zoea VIII of still lacks pleopods and fifth pereiopod, this shrimp likely has at least 12 zoeal stages and a larval development of 120 days.
1902年,深海樱虾属(Doflein)的幼体首次在实验室中成功培育。幼体在36天内发育到了第八期蚤状幼体阶段,这两项都是该属的最长记录。樱虾属早期幼体阶段具有樱虾科虾类的一般特征,与已知幼体形态的其他两个樱虾属物种在以下方面存在差异:头胸甲前腹缘的棘数、触角上的瘤数、触角内肢节段以及第三颚足刚毛。尽管樱虾属的成员通常被分为不同的物种组,但同一物种组的成员不一定具有相似的早期幼体形态。由于该樱虾属的第八期蚤状幼体仍缺乏腹肢和第五步足,这种虾可能至少有12个蚤状幼体阶段,幼体发育时间为120天。
