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。

ムナフセッカ

The cloud cisticola (Cisticola textrix) is a small passerine bird in the family Cisticolidae native to the grasslands of South Africa and Lesotho. It inhabits short open grasslands, karoo scrub, and montane grasslands at elevations up to 3,000 meters in the Drakensberg highlands, where males perform conspicuous high-altitude song flights that give the species its common name. The plumage is cryptically streaked brown and buff above, helping the bird blend into its grass habitat, with a short tail and fine bill adapted for insectivory. Like other cisticolas, C. textrix constructs a characteristic purse-shaped woven grass nest hidden deep within tussock grass. The species is endemic to southern Africa, with the core range centered on the South African highveld and Lesotho highlands. It feeds on small invertebrates gleaned from grass stems and the ground surface. Cloud cisticola populations face pressure from conversion and degradation of native grasslands through overgrazing, agricultural expansion, and inappropriate burning regimes affecting the open grassland habitats it requires throughout its southern African range.
