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.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
