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。

ニッケイオウギセッカ

The cinnamon bracken warbler (Bradypterus cinnamomeus) is a skulking, secretive bird in the family Locustellidae, endemic to the highlands of East Africa. It inhabits dense bracken fern, rank grass, scrub, and the undergrowth of montane forest margins at elevations from approximately 1,500 to 3,200 meters, from Ethiopia and Uganda south through Kenya, Tanzania, Rwanda, Burundi, and the Democratic Republic of Congo. The plumage is rich cinnamon-brown above and paler below with streaked flanks, providing excellent camouflage in its dense vegetative habitat. The species produces a distinctive loud, churring, or musical song that is heard more often than the bird is seen. The cinnamon bracken warbler is classified as Least Concern by the IUCN, with stable populations across its East African highland range. It is absent from Europe entirely; Norwegian database records are geographic data errors. Montane grassland and forest edge habitats in the East African highlands support remarkable bird diversity, including many endemic species. While the cinnamon bracken warbler's habitat faces some pressure from agricultural expansion at forest margins, its adaptability to bracken fern and secondary vegetation provides resilience. It is a popular target species for birdwatchers visiting montane sites in Kenya and Uganda.
