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。

コロンビアヒメクイナ

<em>Neocrex colombiana</em>, commonly known as the Colombian Crake, is a bird species belonging to the genus <em>Neocrex</em> within the family Rallidae, a group of typically secretive marsh and wetland birds. This species is classified as Data Deficient, indicating that current information is insufficient to accurately determine its conservation status, and that further survey work is required to understand its population size and trend. It has been documented in Colombia and Ecuador, where it inhabits various environmental settings consistent with rallid ecology, including wetlands, marshy grasslands, and dense vegetation near water. Rails and crakes in this family are generally omnivorous, feeding on invertebrates, seeds, and small vertebrates, though specific dietary records for this species have not been documented. Biological traits of this species remain poorly documented in the scientific literature. The secretive nature of rallid birds, combined with their preference for dense habitats, makes population surveys challenging. Comprehensive field surveys using acoustic monitoring are considered essential for improving knowledge of <em>Neocrex colombiana</em>.
