A cephalopod arm is distinct from a tentacle, though the terms are often used interchangeably.
By definition, cephalopod arms have suckers along most of their length, as opposed to tentacles, which have suckers only near their ends.[citation needed]
The eight arms of octopuses are usually called such to avoid confusion, as other cephalopods, squid and cuttlefish usually have eight arms and two distinct tentacles. When the context is clear, octopus arms may instead be called tentacles.
