藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

白腹林星蜂鳥

白腹林星蜂鸟（Chaetocercus mulsant）是栖息于哥伦比亚至玻利维亚安第斯山脉及山间谷地的小型林星蜂鸟，雄鸟体重仅约2.5克，是体型最小的蜂鸟之一。雄鸟展示艳丽的紫红色喉斑、白色腹部和绿色胁部。见于海拔1,500至3,500米的林缘和花园。尽管体型娇小，却颇具攻击性且机动灵活，夜间进入蛰伏状态以在寒冷的安第斯环境中节省能量。
