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。

紅腳旋蜜雀

红腿蜜雀（Cyanerpes cyaneus）是一种与唐纳雀有关的小型色彩艳丽的吸蜜鸟，雄鸟展示鲜艳的宝蓝色羽毛和明亮的红腿——这一诊断特征为该种命名——以及细长弯曲、黄色尖端的嘴。分布于从墨西哥向南至玻利维亚、巴西及特立尼达的热带和亚热带森林冠层。用长嘴探入花朵采蜜，其嘴可进入短嘴鸟类无法到达的花朵。是热带冠层树木花朵的重要传粉者，广泛分布于新热带低地湿润森林。
