Of or relating to cephalopods; having the characteristics of the cephalopod class.
From Cephalopoda + '-an' (adjectival suffix). This forms an adjective describing anything belonging to or characteristic of the cephalopod class of mollusks.
Scientists often create '-an' adjectives from noun classifications—we say 'human,' not 'humanan,' but with biological classifications, 'cephalopodan' helps distinguish creatures belonging to this group from other mollusks.
