what are octopus arms called
Octopus “arms” are called arms — not tentacles. The technical distinction is that octopus arms have suckers along the full length, while tentacles usually have suckers only near the tip.
In plain terms
- Octopuses have 8 arms.
- People sometimes say “tentacles,” but that’s not the precise term for an octopus.
- In some contexts, you may also hear their limbs called appendages or limbs.
Quick rule
- Octopus = arms
- Squid = arms and tentacles
TL;DR: Octopus arms are called arms, and the word
“tentacles” is usually incorrect for octopuses.
