Reproductive systems and mating traces of the Sub-Antarctic deep-sea squid Onykia ingens (Cephalopoda: Onychoteuthidae)

We performed quantitative assessment of the reproductive systems of deep-sea species Onykia ingens. Our goals were to: 1) quantify spermatophore production 2) determine the (preferred) location for spermatangia deposition; 3) investigate whether male and female O. ingens mate with multiple mates. Towards this end we examined male and female O. ingens specimens from Falkland Island and New Zealand waters.我们对深海物种长鳍鱿（Onykia ingens）的生殖系统开展了定量评估。本研究的核心目标包括：1）量化精荚（spermatophore）的生成量；2）明确精包（spermatangia）沉积的优选位点；3）探究长鳍鱿的雌雄个体是否存在多次交配行为。为此，我们对采自福克兰群岛及新西兰海域的长鳍鱿雌雄标本进行了检测分析。
