Christmas Cactus

The Christmas cactus (Schlumbergera truncata) is a species of epiphytic cactus in the family Cactaceae, native to the coastal mountains of southeastern Brazil, particularly in the state of Rio de Janeiro. It is one of the most widely cultivated ornamental cacti in the world, grown commercially under the names Thanksgiving cactus or Christmas cactus, and is the primary parent species of the numerous hybrid Christmas cacti available in horticulture. In nature, Schlumbergera truncata grows as an epiphyte in humid Atlantic Forest, attached to tree branches in areas receiving abundant rainfall and fog. Its flattened, segmented stems — phylloclades — have distinctive claw-like teeth along their margins, which distinguish it from the more rounded segments of Schlumbergera bridgesii. Flowers are produced at stem tips in autumn and early winter and range from white through pink, red, purple, and orange, adapted for hummingbird pollination. In cultivation, flowering is induced by exposure to long nights and cooler temperatures. The species tolerates a wider range of conditions than its native epiphytic habitat might suggest, explaining its success as a houseplant globally. In its native Brazilian Atlantic Forest, it faces threats from continued deforestation.

Emperor Penguin

세계에서 가장 큰 펭귄인 황제펭귄(Aptenodytes forsteri)은 키가 최대 1.2m에 몸무게가 45kg에 달하며, 지구상에서 가장 혹독한 환경인 남극 대륙에 서식합니다. 영하 60°C 이하의 한겨울 암흑 속에서 번식하며, 수컷이 암컷이 바다에 있는 동안 65일 동안 발 위에서 육아낭 아래에 알 한 개를 품습니다. 수천 마리가 모인 무리에서 개체들이 따뜻한 중심부를 순환하는 이른바 허들링 행동은 협동적 생존의 훌륭한 사례입니다.
