アルゼンチンフナガモ

The Chubut Steamer Duck (Tachyeres leucocephalus) is a large, flightless or near-flightless diving duck endemic to the Atlantic coast of Patagonia, Argentina, particularly in Chubut Province from which its name derives. It belongs to the genus Tachyeres, commonly known as steamer ducks due to their habit of propelling themselves across the water by flapping their short wings and paddling their large feet simultaneously, resembling a steamboat's paddle wheels. T. leucocephalus is assessed as Vulnerable by the IUCN due to its restricted range along a limited stretch of Patagonian coastline and relatively small total population. The species inhabits rocky coastlines, kelp beds, and sheltered coastal bays, feeding primarily on marine invertebrates including crustaceans, molluscs, and echinoderms obtained by diving in intertidal and subtidal zones. Like other steamer ducks, it is highly territorial, with pairs defending stretches of coastline year-round. The white-headed appearance of adult males gives the species its scientific name leucocephalus. Threats include disturbance from coastal development, oil spills, and persecution. The Chubut coastline and associated marine areas receive some conservation protection, though the species remains at risk from localized catastrophic events.

地球上で最も背の高い動物であるキリン（Giraffa camelopardalis）は体高が5.5mに達し、体重は最大1,750kgにもなる。すべての哺乳類と同じ7個の頸椎からなる長い首は、アフリカのサバンナや疎林のアカシアの木に食物を求めて進化した。永続的な絆を持たない緩やかな群れで生活する社会的動物で、超低周波音と身振りで意思疎通する。生息地の喪失と密猟により個体数が減少している危急種である。
