A squid or an octopus.
Answer 2
A better answer for this question would be: They are an invertebrate in the phylum Mollusca meaning "soft bodied" (Mollusks). The class Cephalopoda means "head foot", meaning their arms and tentacles come from the head. All of their internal organs are cased in the soft section of the body called the mantle. There are actually 4 types of cephalopods: squids, octopuses, cuttlefish, and nautiluses. Each are unique in their own ways. For instance the nautilus is the only cephalopod that does not hunt. They are found in all oceans.
A cephalopod is a snail.
A cephalopod is a mollusk and an invertebrate; it has no skeleton neither external nor internal.
Yes they are
A octopus is a cephalopod that has no shell. Also squid have internal shells that are not used for protection.

The suckers of a cephalopod, such as an octopus or squid, serve multiple crucial functions. They enable the animal to grasp and manipulate objects, aiding in hunting and feeding by allowing the cephalopod to hold onto prey securely. Additionally, the suckers are equipped with sensory cells that help detect chemicals and textures, enhancing the cephalopod's ability to navigate its environment and locate food. This combination of gripping ability and sensory feedback makes the suckers essential for survival.
The only extant cephalopod that produces an external shell is the chambered nautilus. The shells produced by squid and cuttlefish are internal.
