大型クジラの中で最も曲芸的なクジラのひとつであるザトウクジラは、繁殖期にオスが歌う複雑で神秘的な歌で知られており、数時間にわたって続き時間をかけて変化していきます。体長16m、体重30トンに達し、哺乳類の中で最長の回遊を行います。全海洋に分布し、協調的なバブルネット採餌でオキアミや小魚を捕食します。歴史的な捕鯨後の個体数はおおむね回復しています。
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.
