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。

カヤノボリ

<em>Spizixos semitorques</em>, the Collared Finchbill, is a bulbul in the family Pycnonotidae. This species is assessed as Least Concern on the IUCN Red List. It is native to eastern Asia, with its range including southeastern China, Taiwan, and adjacent areas. The Collared Finchbill inhabits forest edges, scrub, and bamboo thickets, and is typically found at middle to higher elevations. Members of the genus <em>Spizixos</em> are characterized by their thick, finch-like bills, which are adapted for feeding on hard-coated seeds and berries in addition to insects. The common name reflects both the collar-like markings on the plumage and the distinctive bill morphology. Diet, population estimates, population trend, and biological measurements including average length, weight, and lifespan are not specified in available records. Biological traits of this species remain poorly documented in the scientific literature. The species is associated with aerial, terrestrial, and aquatic environments within its range. Its Least Concern status indicates stable populations across its eastern Asian range.
