Sai-kabutomushi

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.

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。
