AP BIOLOGY

Detailed explanation-1: -The tentacles are adapted to snatch prey from farther away through their ability to extend and retract. Both the arms and tentacles are equipped with powerful suckers that can function like suction cups.

Detailed explanation-2: -Octopuses use their eight tentacles to envelop and shovel prey into their mouths. Special receptors on their tentacles help octopuses taste objects just by touching them, a new study found. This touch-taste sense helps an octopus detect hidden prey and retreat from objects that taste toxic.

Detailed explanation-3: -How octopus feed. Octopus seek their prey using acute visual or tactile cues. They restrain an animal with their suckers, engulf it in an intertwined mass of arms, and draw it close to them. Most octopus and cuttlefish bite their prey and inject it with paralysing saliva.

Detailed explanation-4: -Anatomically, the tentacles of animals work mainly like muscular hydrostats. Most forms of tentacles are used for grasping and feeding. Many are sensory organs, variously receptive to touch, vision, or to the smell or taste of particular foods or threats.

Detailed explanation-5: -An octopus has eight appendages, each of which has rows of suckers running its length. But these are not tentacles-in strict anatomical terms, they are arms. A tentacle has suckers only on its pad-shaped ending. Squid and cuttlefish have arms, but also tentacles.
