Definition of Cephalopoda in English:


plural noun

  • A large class of active predatory molluscs comprising octopuses, squids, and cuttlefish. They have a distinct head with large eyes and a ring of tentacles around a beaked mouth, and are able to release a cloud of inky fluid to confuse predators.

    • ‘This section covers almost all of the Mollusca except the three huge clades of advanced mollusks: Bivalvia, Cephalopoda, and Gastropoda.’
    • ‘The class Cephalopoda has been traditionally divided into three subclasses on the basis of shell structure, or two subclasses on the basis of gills and other soft parts.’
    • ‘As the most primitive of the Neocephalopoda, they were the ancestors of the Bactridida, which in turn seem to represent the stem group form which all advanced Cephalopoda evolved.’
    • ‘For example, even within Gastropoda and Cephalopoda, large numbers of rearrangements are common.’
    • ‘It is also now generally thought that they were ancestral to the Cephalopoda and Scaphopoda as well.’


Modern Latin (plural), from Greek kephalē head + pous, pod- foot.
