Basic life history information, such as reproductive strategy and embryo development, are lacking in many octopus species, including in the New Zealand species Octopus huttoni. Octopus paralarvae are particularly sensitive to changing temperatures; therefore, this study aimed to determine how temperature affects the egg-laying behaviour and embryo development and the implications on O. huttoni paralarvae survivability in southern New Zealand is discussed. Reproduction was found to occur all year-round, but there was a tendency to lay eggs in the spring and summer, most likely due to the increase in planktonic food production during this time of year. An inverse relationship was observed between temperature and duration of embryo development, in which the shortest duration was 44 days at a mean temperature of 17.3°C and the longest was 158 days at a mean temperature of 12.7°C. It is unknown how this increase in temperature and decrease in development time affects the survivability of the resulting individual, but studies from other species of octopus suggest that this phenomenon can be detrimental to overall paralarval survivability.

章鱼产卵和胚胎发育对温度和季节的响应

许多章鱼物种都缺乏基本的生活史信息，例如生殖策略和胚胎发育，包括新西兰物种 Octopus huttoni。章鱼副幼虫对温度变化特别敏感。因此，本研究旨在确定温度如何影响产卵行为和胚胎发育，并讨论对新西兰南部 O. huttoni paralarvae 存活率的影响。发现全年都可以繁殖，但在春季和夏季有产卵的趋势，这很可能是由于一年中这个时候浮游食物产量的增加。在温度和胚胎发育持续时间之间观察到反比关系，其中最短持续时间为 44 天，平均温度为 17。3°C，最长的为 158 天，平均气温为 12.7°C。目前尚不清楚这种温度升高和发育时间缩短如何影响最终个体的生存能力，但对其他章鱼物种的研究表明，这种现象可能不利于整体准幼虫的生存能力。
