Comet Darner

<em>Anax longipes</em>, the comet darner, is a large dragonfly in the family Aeshnidae, assessed as Least Concern on the IUCN Red List. It is endemic to the United States, where it inhabits lakes, ponds, and slow-moving rivers with clear water and abundant emergent vegetation. The comet darner is one of the largest North American dragonflies and is distinguished by its brilliant coloration, including a green thorax and a red-spotted abdomen in mature males. The species name longipes refers to its notably long legs. Adults are powerful aerial predators, feeding on a variety of flying insects captured in flight. Larvae are aquatic and predatory, developing in the benthic zone of freshwater habitats where they feed on invertebrates and small vertebrates. The comet darner undertakes seasonal dispersal movements and is most commonly observed near its breeding water bodies during the warmer months.

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。
