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.
