Common Blanket Octopus

The common blanket octopus (<em>Tremoctopus violaceus</em>) is a remarkable pelagic cephalopod mollusc classified as Least Concern on the IUCN Red List, with records indicating its presence in Asian waters, including around Taiwan. The species exhibits extreme sexual dimorphism: females can reach lengths of up to two meters when the cape-like webbing between their dorsal arms is extended, while males are tiny, reaching only a few centimeters. The distinctive webbing, which resembles a flowing blanket, is thought to serve as a defense mechanism, being extended to confuse or deter predators. Females are also known to detach and wield tentacles from the Portuguese man-of-war, to which they are immune, using them as defensive weapons. <em>Tremoctopus violaceus</em> typically inhabits open oceanic waters across tropical and subtropical seas. Biological traits of this species remain poorly documented in the scientific literature.

帝企鹅

帝企鹅是世界上体型最大的企鹅，身高可达1.2米，体重达45千克，栖息于南极大陆极端恶劣的环境中。它们在隆冬的黑暗中、零下60°C以下的严寒里繁殖，雄鸟将唯一的蛋置于脚背上，藏于育卵囊下孵化长达65天，而雌鸟则在此期间出海觅食。数千只帝企鹅组成的群体通过循环交换位置、使个体轮流经过温暖的核心区域这一抱团取暖行为，堪称合作生存的典范。
