The presence of sperm storage was evaluated in several deep-sea elasmobranchs (Centrophorus squamosus, Centroselachus crepidater, Deania calcea, Brochiraja spinifera, Brochiraja asperula, Apristurus ampliceps, A. exsanguis, A. garricki and A. sinensis), all considered at risk to the impacts of fishing in New Zealand. Biological measurements of reproductive organs (e.g. follicle size and number, oviducal gland size, uterus width and gonad weight) were recorded in addition to conventional macroscopic maturity assessment measures. Histology was conducted on a sample of oviducal glands to investigate the occurrence of sperm storage. Sperm storage was confirmed in three of the nine species: Centroselachus crepidater, Centrophorus squamosus and Brochiraja asperula. To the best of our knowledge, these are the first observations of sperm storage for these genera, and the first in the family Centrophoridae. Sperm storage was observed in macroscopically mature females and also in some females considered macroscopically as maturing. The female reproductive tract may regress substantially between reproductive events to the extent that a mature fish is mis-classified as maturing, and would be consistent with long periods of resting between reproductive events. Alternatively, it is equally possible that aggrieve male mating behaviour results in premature copulation of maturing females. We summarise published occurrences of sperm storage in chondrichthyans, and conclude that sperm storage is most likely ubiquitous in chondrichthyans, and an adaptive benefit to traumatic mating behaviour, that may also be adaptive to low fish densities in the relatively unproductive environment of the deep-sea.

在几个深海的弹性分支中评估了精子储存的存在（Centophorus squamosus，Centroselachus crepidater，Deania calcea，Brochiraja spinifera，Brochiraja asperula，Apristurus ampliceps，A。exsanguis，A。garricki和A. sinensis）。在新西兰捕鱼的影响。除常规的宏观成熟度评估措施外，还记录了生殖器官的生物学测量值（例如，卵泡大小和数量，输卵管腺​​大小，子宫宽度和生殖腺重量）。对输卵管腺样本进行了组织学检查，以研究精子储存的情况。九种物种中的三种证实了精子的储存：Centroselachus crepidater，Scentophorus squamosus和Brochiraja asperula。据我们所知，这是这些属的精子贮藏的第一批观察结果，也是Cenophoridae科的第一批观察结果。在宏观上，观察到精子存储成熟女性和也在有些女性宏观看作成熟。雌性生殖道可能在生殖事件之间大量退化，以至于成熟鱼被错误地归类为成熟，并且与生殖事件之间的长时间休息相一致。或者，同样有可能使雄性的交配行为不愉快而导致成年雌性过早交配。我们总结了软骨鱼中精子存储的已发表事件，并得出结论，精子存储在软骨鱼中最可能普遍存在，并且对创伤性交配行为具有适应性好处，这也可能适应于相对低产的深海环境中的低鱼密度。
