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。
ナナスジホオジロ
The cinnamon-breasted bunting (Emberiza tahapisi), also called the rock bunting or cinnamon-breasted rock bunting, is a small passerine in the family Emberizidae, widely distributed across sub-Saharan Africa and extending into the Arabian Peninsula and parts of western Asia. It inhabits rocky hillsides, boulder-strewn slopes, dry scrub, and open woodland with rocky outcrops, from sea level to highland elevations across its vast African range. The male is distinguished by bold streaky brown upperparts, a black and white striped head, and a rich cinnamon breast—its namesake feature. The species forages on the ground for seeds and invertebrates. The cinnamon-breasted bunting is classified as Least Concern by the IUCN, with a large, continuous African range and populations considered stable. It is one of the most widespread buntings in Africa. The species is entirely absent from Europe and Norway; database records to the contrary are errors arising from data entry or coordinate mistakes in species databases. This bunting is a common and conspicuous species throughout its African rocky habitat, often singing from prominent boulders. It is non-migratory across most of its range, though some montane populations may make limited altitudinal movements seasonally.
