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。

顫鳴扇尾鶯

The churring cisticola (Cisticola njombe) is a small insectivorous warbler in the family Cisticolidae, endemic to the highlands of East Africa. It inhabits montane grasslands, bracken-fern slopes, and the margins of high-altitude forest patches, primarily in the Nyika Plateau, the Njombe highlands of southern Tanzania, and adjacent areas of Malawi and Zambia. The species occupies elevations typically between 1,500 and 2,500 meters, where it forages low in dense grass and sedge clumps, gleaning insects and small invertebrates. The churring cisticola is named for its distinctive mechanical churring song, which males produce from low perches or during short display flights. It is a compact, streaked brown bird with a rufous-washed tail and pale underparts, closely resembling related montane cisticolas. The species is classified as Least Concern by the IUCN, with populations considered stable across its restricted highland range. Like other afromontane endemics, it depends on the persistence of intact highland grassland ecosystems, which face ongoing threats from agricultural encroachment, fire management changes, and human settlement. Taxonomic relationships within the Cisticola genus are complex, and the njombe cisticola has been subject to periodic revision. Conservation of afromontane grasslands in Tanzania and Malawi is critical for this and many co-occurring endemic species.
