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。

Chocolate Tea Tree Orchid

The Chocolate Tea Tree Orchid (Dendrobium johannis) is an epiphytic to lithophytic orchid in the family Orchidaceae, endemic to northern Queensland, Australia and southern Papua New Guinea. It belongs to the vast genus Dendrobium, one of the largest orchid genera with over 1,800 species across tropical and subtropical Asia, the Pacific, and Australia. Dendrobium johannis produces cane-like pseudobulbs bearing narrow, leathery leaves, and clusters of small to medium-sized flowers with creamy white to pale yellow petals and a lip marked with chocolate-brown to maroon blotches and stripes — a patterning that may serve to attract specific bee pollinators through visual mimicry or reward signalling. In the wild, the species grows on tea trees (Leptospermum, Melaleuca), paperbarks, and other trees in seasonal tropical woodland, gallery forest, and savanna margins in the Top End and Cape York regions. It tolerates distinct wet and dry seasons, losing some foliage during dry conditions. The IUCN classifies this species as Near Threatened, reflecting pressures including habitat clearing for agriculture, altered fire regimes, and collection for the horticultural trade. It is cultivated by orchid enthusiasts worldwide and has been used in hybridisation programmes.
