Have you ever wondered what the difference is between an octopus and a squid? While they are similar in many ways, they are also different in others. I will talk about both the similarities and the differences between their physical characteristics, their habitat, and their behavior. The octopus and the squid are both similar and different in the way they look. They’re closely related to mollusks. Squids have a backbone-like structure that is flexible which is similar to the shell of a snail. The octopus doesn’t have a shell nor a stiff structure and have soft bodies. Both belong to the cephalopod group and have blue blood, are head-footed animals with 8 arms, and possess both a mantle and a head. Squids have 2 tentacles arranged in pairs
