What does octopod mean?
An octopod is a member of the biological order Octopoda, the group that includes octopuses and their close relatives. Its name reflects a defining characteristic: eight arms joined around the head, each equipped with structures that can grip surfaces, explore crevices, and manipulate objects. The word occurs chiefly in zoology, taxonomy, and natural-history writing, whereas octopus is normally preferred in general descriptions of these animals. Using octopod can sound precise and slightly formal, as when referring collectively to an organism within the broader order rather than simply to the familiar octopus. The term also distinguishes octopuses from other cephalopods, such as squid and cuttlefish, although their anatomical differences are more extensive than a simple count of arms suggests. Despite being less frequent in ordinary language, octopod is a useful term for discussing classification, morphology, and evolutionary relationships with scientific clarity.
nounAn animal belonging to the order Octopoda, especially the common octopus; more generally, any eight-armed cephalopod.
- A cephalopod of the order Octopoda, having eight arms; especially, an octopus.
"An octopod moved silently across the reef, its arms probing beneath the stones."

Octopod is not merely “octopus” with a fancier spelling: it is the broader zoological label for members of the order Octopoda.

Where does octopod come from?
The name comes from Greek oktō, meaning “eight,” and pous, podos, meaning “foot,” referring to the animal’s eight appendages. English uses the related form octopod chiefly in zoological and taxonomic contexts. Its cognates include octopus, from Greek oktōpous, and the French word poulpe, which came through Latin from the same Greek source.
How octopod is actually used
The word is chiefly formal or technical and is less common than octopus in everyday speech. In American English, the final syllable may be pronounced with an /ɑ/ sound rather than the British /ɒ/.
