Question

Why does an octopus or squid use its tentacles?

Answer 1

Squid have 10 arms. Two of their arms are longer than the other eight and are called tentacles. ... The squids' two tentacles are specially adapted for feeding and they use them to grab their prey. They have a sharp beak on their mouths that they use to break open shells.

Answer 2

Octopus and squid have little suction cups on their tentacles. It helps with sticking onto food (so it doesn't get away) and also helps with sticking into things. If it wanted to camouflage into some rocks, it can use its tentacles to cling to to the rock.

Tentacles can also grab and carry things. Scientists have made tests where they would put a clam in a jar with the lid screwed on. The octopus would grab onto the jar and use its tentacles to twist the lid off.

Without tentacles, octopuses and squids would be pretty helpless and probably couldn't survive in the deep ocean.
