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。

Common Hooktail

<em>Paragomphus genei</em>, commonly known as the common hooktail, is a dragonfly in the family Gomphidae. It is classified as Least Concern on the IUCN Red List, suggesting a stable and widespread population. The species is noted to occupy virtually all terrestrial and freshwater habitats within its range, reflecting considerable ecological generalism typical of many gomphid dragonflies. Specific country-level distribution records for this species are not detailed in current data, though the breadth of habitat use implies a relatively wide geographic range across suitable regions. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
