- A cephalopod arm is a limb of a cephalopod, which is often treated as distinct from a tentacle, though the terms are sometimes used interchangeably1. Arms have suckers along most of their length, as opposed to tentacles, which have suckers only near their ends1. The arms of cephalopods are flexible, prehensile appendages that surround the mouth and are attached to each other near their base by a webbed structure2. The arms can be described based on side and sequence position and divided into four pairs2.Learn more:✕This summary was generated using AI based on multiple online sources.

Generally, arms have suckers along most of their length, as opposed to tentacles, which have suckers only near their ends.en.wikipedia.org/wiki/Cephalopod_limbThe foot has evolved into a set of flexible, prehensile appendages, known as "arms", that surround the mouth and are attached to each other near their base by a webbed structure. The arms can be described based on side and sequence position (such as L1, R1, L2, R2) and divided into four pairs.en.wikipedia.org/wiki/Octopus
