仙人掌地雀

<em>Geospiza scandens</em>, commonly known as the common cactus finch, is a bird species found in Ecuador and with records from Norway. It typically inhabits aerial, terrestrial, and aquatic environments, often closely associated with arid island ecosystems where cacti are prevalent. The species is classified as Least Concern on the IUCN Red List, indicating that it is not currently at risk of significant population decline at a global level. The common cactus finch belongs to the genus <em>Geospiza</em> within the family Thraupidae and is among the iconic Darwin's finches of the Galápagos Islands. It typically feeds on the nectar, pollen, and seeds of cactus plants, particularly <em>Opuntia</em>, and plays an important role as a pollinator and seed disperser within its island habitat. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature. Population trends are considered stable, and the species remains an important subject of evolutionary and ecological research.

koala

澳大利亚东部和东南部的标志性有袋类动物，体重最大可达15千克，为了节省低热量桉树叶食物所提供的能量，每天最多睡眠22小时。高度特化，能够处理会致大多数其他哺乳动物死亡的有毒桉树成分，拥有专门适应解毒功能的肠道微生物群。因衣原体病、栖息地开发和气候变化导致种群锐减，2022年被列为濒危物种。
