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。

Coastal Mahoe

Melicytus novae-zelandiae, the coastal mahoe, is a shrub or small tree in the family Violaceae native to New Zealand, where it occurs along the coastlines of both the North and South Islands, extending to some offshore islands. The mahoes are a characteristic group of small trees and shrubs in the New Zealand flora, and M. novae-zelandiae is distinguished as the coastal ecotype of this group, tolerating salt spray, coastal winds, and the harsh conditions of maritime scrub and coastal forest margins. The species typically reaches 2–6 meters in height and produces small, yellowish-green flowers followed by fleshy purple to black fruits that are eaten by native birds including silvereyes, bellbirds, and tuis that disperse seeds through coastal scrub. Coastal mahoe provides important food and shelter resources in coastal bird habitats. Like other New Zealand violets in Melicytus, the plants are dioecious, with separate male and female individuals. The species is classified as Least Concern by the IUCN, being a naturally common component of coastal New Zealand vegetation and capable of persisting in modified coastal habitats including regenerating scrub and planted gardens. It is used in coastal revegetation and gardening for its wind and salt spray tolerance.
