Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador, Venezuela).

Christmas orchid

The Christmas orchid (Calanthe triplicata) is a terrestrial orchid in the family Orchidaceae, distributed across a wide range spanning tropical and subtropical Asia, the Pacific islands, and northern Australia. It is one of the most widespread species in the diverse genus Calanthe, which comprises over two hundred species of ground-dwelling orchids. Calanthe triplicata produces an elongated inflorescence bearing numerous small, pure white flowers with a yellow center, creating a striking display. The flowers are borne on an upright spike arising from a pseudobulb — a water-storing stem structure characteristic of the genus. In parts of Australia the species blooms around the Christmas period, contributing to its common name. It typically grows in moist tropical and subtropical forests, often in deep leaf litter on the forest floor, and is adapted to humid, shaded conditions with good drainage. The wide distribution of Calanthe triplicata across multiple countries and habitats makes it relatively secure compared to many orchid species. However, like all wild orchids, it is potentially affected by habitat loss, illegal collection, and disturbance to forest ecosystems. The species is listed under CITES Appendix II, requiring regulated international trade.

Epaulard

イルカ科で最大の種であるシャチ（Orcinus orca）は体長最大9メートル、体重6トンに達し、北極から南極まですべての海洋に生息しています。独特の方言、狩猟戦略、集団間で異なる文化的伝統を持つ母系ポッドで生活する頂点捕食者です。一部の集団は魚類を、他の集団は海洋哺乳類を専門に捕食します。天敵はなく、シャチは生息するすべての海洋食物連鎖の頂点に位置します。
