Colonia Robber Frog

Eleutherodactylus audanti, the Colonia robber frog, is a direct-developing frog in the family Eleutherodactylidae assessed as Vulnerable by the IUCN. Members of the genus Eleutherodactylus are notable for their direct development, bypassing the free-living tadpole stage entirely and hatching as miniature froglets from terrestrial eggs, a reproductive strategy that reduces dependence on standing water for breeding. This species inhabits freshwater-associated environments, moist tropical forests, and wetland margins, occupying humid microhabitats within the leaf litter and understorey vegetation. The Vulnerable assessment reflects population declines associated with habitat loss, chytrid fungal disease, and potentially climate-driven changes in forest moisture regimes. Robber frogs in this genus feed opportunistically on small invertebrates encountered in their forest floor microhabitat. Eleutherodactylus audanti has not been confirmed from any specific country according to current records, suggesting either a highly restricted or poorly documented distribution. Conservation of moist forest habitats is considered essential to the long-term survival of this species. Biological traits of this species remain poorly documented in the scientific literature.

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。
