Coastal Red-rumped Frog

Coastal red-rumped frog (Eleutherodactylus paralius) is a small direct-developing frog in the family Eleutherodactylidae, endemic to lowland coastal forests and their margins in Cuba and possibly other Caribbean islands. Like all members of the speciose genus Eleutherodactylus, it bypasses an aquatic larval stage, with embryos developing directly within the egg into miniature froglets. The species inhabits humid leaf litter, root tangles, and low vegetation in coastal forest and scrub, emerging nocturnally to forage for small invertebrates including insects and arachnids. The common name refers to reddish or orange coloration on the posterior flanks or groin, which may serve as an aposematic signal or camouflage disruptive pattern. Eleutherodactylus is the most species-rich vertebrate genus on Earth, with hundreds of species distributed across the Caribbean and the Americas. Coastal red-rumped frog is assessed as Near Threatened by the IUCN, reflecting pressure from habitat loss driven by coastal development, logging, and the spread of chytrid fungus, which has devastated amphibian populations globally. Monitoring and habitat protection are critical for its persistence.

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。
