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。

紫背彩裸鼻雀

紫肩唐纳雀（Iridosornis porphyrocephalus）是深紫蓝色肩背与栗色胁部、黑色脸部和翅膀形成强烈对比的华美安第斯唐纳雀。分布于哥伦比亚和厄瓜多尔海拔1000至2200米的湿润云雾林和林缘。雄鸟在林冠光线下展现出闪亮彩虹般的紫色肩背羽毛。成对或小群活动于林内及林缘，取食果实和昆虫。因哥伦比亚和厄瓜多尔云雾林大量砍伐而被列为易危（VU）。
