combed octopus

藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

combed octopus

<em>Eledone massyae</em>, 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 <em>Eledone</em>, 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 <em>Octopus</em>. <em>E. massyae</em> 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.
