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。

ムナグロマユシトド

The Collared Warbling Finch, known scientifically as <em>Poospiza hispaniolensis</em>, is a small passerine bird belonging to the family Thraupidae, the tanagers and allies. <em>Poospiza hispaniolensis</em> is characterised by its neatly patterned plumage, which typically features contrasting black-and-white head markings and a distinctive collar or chest band element consistent with other members of the warbling finch group. The species typically inhabits scrubby, arid, and semi-arid environments, foraging for seeds and small invertebrates in low vegetation and on the ground. It is reported to occur in Ecuador and Norway. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Warbling Finch is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is stable without significant conservation concerns.
