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.

コウテイペンギン

世界最大のペンギンであるコウテイペンギン（Aptenodytes forsteri）は体高最大1.2m、体重45kgで、地球上で最も過酷な環境の一つである南極大陸に生息しています。零下60°C以下の真冬の暗闇の中で繁殖し、雌が海上にいる間、雄が65日間足の上で育雛嚢の下に一つの卵を温め続けます。数千羽からなる群れで個体が暖かい中心部を循環するいわゆるハドリング行動は、協調的な生存戦略の傑作です。
