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。

海岸扇尾莺

Cisticola haematocephalus, the coastal cisticola or red-headed cisticola, is a small passerine bird in the family Cisticolidae distributed across sub-Saharan Africa, inhabiting rank coastal and lowland grassland, tall reed beds adjacent to water bodies, and scrubby vegetation along rivers and wetland margins. The genus Cisticola, with over 50 species, represents one of the most speciose avian genera in Africa and is characterized by small, brown-streaked warblers that are notoriously difficult to distinguish in the field and are often best identified by voice. Cisticola haematocephalus is recognized by the rufous-chestnut crown that gives it its common and scientific names, distinguishing it from the numerous plain-crowned cisticola species with which it often shares habitat. Males perform conspicuous aerial display songs during the breeding season from exposed grass stems or in fluttering display flights. The species is assessed as Least Concern by the IUCN, being widespread across coastal and riverine lowlands of east, west, and central Africa. It constructs a characteristic deep, oval woven grass nest anchored within tall grass stems, often partially concealed by living grass folded around the nest entrance.
