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。

クロガオセッカ

Chubb's Cisticola (Cisticola chubbi) is a small, streaked warbler-like bird in the large African genus Cisticola (family Cisticolidae), named for the British naturalist Charles Chubb. It inhabits montane grasslands and forest margins in the highlands of sub-Saharan Africa, with populations recorded from the mountains of eastern and central Africa including the Albertine Rift region, Ethiopia, and Uganda. Like most cisticolas, C. chubbi is a non-migratory resident of open grassy habitats, where males produce characteristic repeated calls from elevated perches during the breeding season. The species is assessed as Least Concern by the IUCN, reflecting its wide distribution across African highland grasslands and the absence of evidence for major population declines. Its diet consists primarily of insects and small invertebrates gleaned from grass stems and the ground surface. Cisticola taxonomy has been subject to extensive revision, and the chubbi species group includes several geographically distinct forms that may represent separate species. Habitat degradation from overgrazing, agricultural encroachment, and scrub invasion into montane grassland represents a long-term threat to the species and its associated grassland community across its African range.
