根据对一只圈养雌性的近距离观察，描述了一只日本飞鱼(Todarodes Pacphaus)的产卵行为。鱿鱼首先从一个10吨重的水箱中转移到一个装有45升海水的聚苯乙烯塑料盒中。大约一个小时后，外套膜收缩速度迅速增加，随后外套膜和手臂短暂抽搐，身体变白。外套膜的收缩变得浅而迅速，几秒钟后，半透明的果冻从漏斗中冒出来，从腹侧的一对手臂之间通过。在卵块首次出现后大约90 秒，雌性开始通过漏斗将卵母细胞通过漏斗排入卵块，使用快速、强大的地幔收缩。卵母细胞排出后不久，半透明的线束(可能是精子)就从颊上膜中排出。雌性继续排出卵母细胞约两分钟，之后外套膜痉挛，外套膜收缩速率缓慢下降约一分钟，直到收缩停止。不久之后，乌贼就死了。
The spawning behavior of a Japanese flying squid (Todarodes pacificus) is described based on up-close observation of a captive female. The squid was first transferred from a 10-ton tank to a polystyrene plastic box containing 45 liters of seawater. About one hour later, the mantle-contraction rate increased rapidly, followed by a brief convulsion of the mantle and arms and a whitening of the body. The mantle contractions become shallow and rapid, and several seconds later, semitransparent jelly presumably from the nidamental glands emerged from the funnel and passed between the ventral pair of arms. Approximately 90 seconds after the egg mass first emerged, the female began ejecting oocytes through the funnel into the egg mass using rapid, powerful mantle contractions. Soon after the oocytes were ejected, translucent strands (presumably sperm) emanated from the buccal membrane. The female continued to eject oocytes for approximately two minutes, after which the mantle convulsed, and the mantle-contraction rate decreased slowly for about one minute until the contractions stopped. The squid died soon afterwards.
