Tentacles vs. Arms: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on December 13, 2023
Tentacles are elongated, flexible appendages often found in marine animals for sensation or grasping, whereas arms are limb extensions in humans and some animals used for movement and manipulation.

Key Differences

Tentacles are typically slender, elongated, and flexible, found in animals like octopuses and squids, primarily used for sensing, grasping, or moving. Arms, on the other hand, are the upper limbs of humans and some animals, structured with bones and muscles, used for a wide range of motions and tasks.
