Gonatus onyx is one of the most abundant cephalopods in the Pacific and Atlantic Oceans and is an important prey species for a variety of vertebrate predators, but a full understanding of its life history has been hampered because spawning occurs at great depths, where observation is difficult. Here we describe post-spawning egg care, or brooding, in this deep-sea squid. Our finding is unexpected because this behaviour differs from the reproductive habits of all other known squid species.
大耳乌贼是太平洋和大西洋中数量最为丰富的头足类动物之一，也是多种脊椎动物捕食者的重要猎物，但由于其产卵发生在深海，难以进行观察，因此对其生活史的全面了解受到了阻碍。在此，我们描述了这种深海鱿鱼产卵后的护卵行为，即抱卵行为。我们的发现出人意料，因为这种行为与所有其他已知鱿鱼物种的繁殖习性不同。
