海鸟和海洋哺乳动物大部分时间生活在远离人类观察的开阔海洋中，这使得获取它们觅食行为的信息变得困难。在这里，我们通过使用一种小型数码相机系统，展示了（据我们所知）自由活动的企鹅水下群体行为的首个直接证据。在可能的觅食潜水中，有24%的时间企鹅会与其他鸟紧密相伴游泳。这一发现证实，这种小型相机技术对于增进我们对海洋动物在深海中先前未知的社会互动的了解具有广泛的适用性。
Marine birds and mammals spend most of their lives in the open ocean far from human observation, which makes obtaining information about their foraging behaviour difficult. Here, we show, by use of a miniaturized digital camera system, the first direct evidence (to our knowledge) of underwater group behaviour in free-ranging penguins. Penguins swim closely accompanied by other bird(s) during 24% of their possible foraging dives. This finding confirms that such miniaturized camera technology has broad applicability for advancing our knowledge about the previously unknown social interactions of marine animals at depth.
