地球上で生きたことが知られている最大の動物であるシロナガスクジラ（Balaenoptera musculus）は、体長33メートル、体重200トンに達することができ、心臓だけで小型自動車ほどの重さがあります。全ての海洋に生息し、極地の餌場と熱帯の繁殖地の間を回遊します。1日最大4トンのオキアミを摂取する濾過摂食者です。20世紀の捕鯨による絶滅危機からの回復後、世界的な個体数は10,000〜25,000頭と推定される絶滅危惧種です。

ノドジロセッカ

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.
