combed octopus

Eledone massyae, the combed octopus, is a cephalopod mollusc in the family Octopodidae, assessed as Least Concern on the IUCN Red List. As a member of the genus Eledone, it is distinguished from true octopuses by possessing a single row of suckers on each arm rather than the double row characteristic of the genus Octopus. E. massyae is a benthic predator that uses its arms and suckers to capture and subdue prey, which typically includes crustaceans, fish, and other invertebrates. Like all cephalopods, it possesses a highly developed nervous system and sophisticated behaviors including the ability to change skin color and texture for camouflage. Specific habitat description and geographic range data are not available for this species in the current record. The organism does not maintain biological traits such as a fixed body length or mass across individuals in a consistent manner for reporting here.

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。
