Shiro-shumokuzame

The common hammerhead, <em>Sphyrna zygaena</em>, is a cartilaginous fish belonging to the order Carcharhiniformes, family Sphyrnidae. This species is typically found in marine environments and has a distribution that includes the waters of Chile, Denmark, Portugal, Sweden, and Taiwan, reflecting a wide range across both Atlantic and Pacific Ocean systems. As a hammerhead shark, <em>Sphyrna zygaena</em> possesses the characteristic cephalofoil, the laterally expanded head structure that provides enhanced sensory capabilities and hydrodynamic benefits. Hammerhead sharks are generally known to be active, wide-ranging predators within marine ecosystems. No dietary information has been provided for this specific species in current records. 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。
