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。

マルハシミツドリ

The cinereous conebill (Conirostrum cinereum) is a small, active bird in the family Thraupidae, found across the Andes from Colombia and Ecuador south to northern Chile and northwestern Argentina. It inhabits open scrubby habitats, Polylepis woodland, shrubby grassland, and the margins of montane forest at elevations typically between 1,500 and 4,500 meters, making it one of the highest-elevation conebills. The plumage is gray above and pale below, with a distinctive conical bill adapted for probing flowers and gleaning insects. The cinereous conebill is classified as Least Concern by the IUCN, with a wide Andean distribution and populations considered stable. It is a common component of high-Andean bird communities, often joining mixed-species foraging flocks that exploit nectar and insects across a range of shrubby montane habitats. Its range is entirely within the Andes of western South America, and any database record listing Norway is a data entry artifact. The conebills (Conirostrum) are a genus of small tanagers specialized for exploiting flowers and bark crevices, with several species distributed across Andean and Amazonian habitats. Conservation of Andean montane vegetation, including the critically threatened Polylepis woodland ecosystem, is important for this and many co-occurring highland specialists.
