摘要：描述了大西洋小型短尾乌贼（Sepiola atlantica）在自然基质中的掩埋行为模式，对不同阶段的动作以及与该行为相关的颜色变化进行了定量区分。所有样本都呈现出相同的两部分掩埋序列，这引发了该物种特有的颜色变化展示。我们的研究结果表明，这是掩埋过程中一种一致的行为。警戒姿势的平均潜伏期为9.55±5.49秒。第一阶段的平均持续时间为12.2±4.37秒。第二阶段的平均持续时间为10.2±2.95秒。完成该行为模式平均花费的时间为21.9±4.93秒。掩埋时间与大小无关。个体之间观察到的差异与每个阶段的动作数量有关。然而，这些动作与动物的大小没有显著相关性。对该物种与耳乌贼科其他成员的掩埋模式进行了比较。
Abstract The burying behavioural pattern of the small Atlantic bobtail squid (Sepiola atlantica) in natural substrate is described, quantitatively differentiating the movements in different phases and the chromatic changes associated with this behaviour. All specimens showed the same two-part sequence of burying, which triggered a display of colour changes peculiar to this species. Our results suggested that this was a consistent behaviour during burial. The mean latency time in the alert posture was 9.55 ± 5.49 s. The mean duration of the first phase was 12.2 ± 4.37 s. The mean duration of the second phase was 10.2 ± 2.95 s. The average time spent completing the behavioural pattern was 21.9 ± 4.93 s. Burying time was not related to size. Differences observed between individuals were associated with the number of movements in each phase. However, these movements were not significantly related to the size of the animals. A comparison of the burying pattern of this species with other members of the family Sepiolidae is made.
