Coconut rhinoceros beetle

The Coconut Rhinoceros Beetle (Oryctes rhinoceros) is a large scarab beetle in the family Scarabaeidae, notorious as one of the most destructive insect pests of coconut and oil palms across tropical Asia and the Pacific. Adult beetles measure 40–60 millimetres in length and are characterized by a prominent horn projecting from the head of males, used in intraspecific combat for mating access. Adults bore into the growing apex of palm crowns to feed on sap, creating characteristic V-shaped cuts in fronds and weakening trees so severely that they may die. Larvae develop in decaying organic matter, particularly rotting logs, compost heaps, and dead palm trunks. Native to South and Southeast Asia, the beetle has spread through accidental introduction to the Pacific Islands, including Palau, Guam, Hawaii, and the Solomon Islands, where it threatens both agricultural productivity and native palm ecosystems. In Mauritius, introduced populations have caused significant damage to ornamental and cultivated palms. Biological control programs employ the Oryctes nudivirus and entomopathogenic fungi such as Metarhizium anisopliae to suppress populations. Integrated pest management strategies combining pheromone trapping, sanitation of breeding sites, and biological agents have met with variable success. The species is not formally evaluated for conservation status given its pest rather than threatened nature.

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.
