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。

ラケットカワセミ

<em>Tanysiptera galatea</em> is a strikingly colored kingfisher in the family Alcedinidae, native to the Maluku Islands and New Guinea in the Australasian region. The species is characterized by elongated central tail feathers, a vivid blue and white plumage, and a distinctive red bill. It inhabits lowland tropical forests, forest edges, and secondary growth, where it forages for invertebrates, small lizards, and earthworms typically caught by diving to the ground from low perches. The species nests in arboreal termite mounds, excavating tunnel nests that provide insulation and protection. Its occurrence record in Norway is a clear database artifact; the true range is confined to the islands of eastern Indonesia and New Guinea. The IUCN classifies this species as Least Concern owing to its broad distribution and large populations across suitable forest habitats. Biological traits including average lifespan, body length, and body weight are not consistently recorded across populations in standardized databases, and detailed dietary data remain poorly documented. Conservation concerns center on the continued integrity of lowland forests within its range, particularly in areas facing agricultural conversion and logging pressure.
