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。

斑纹舞雀

纹胸唐纳雀（Saltator striatipectus）是一种栖息于哥伦比亚、厄瓜多尔和巴拿马太平洋沿海低地的中型唐纳雀，因胸部和两胁有浓密的棕褐色和白色条纹而得名。栖息于林缘、灌丛和次生林，成对或小群采食种子和果实。被列为无危种，但其分布范围局限于因农业扩张和毁林而日益受到威胁的太平洋低地生境。它们会发出唐纳雀特有的悦耳哨声。
