bilateral symmetry
Pisces are fish and an Octopus is a cephalopod. For instance fish show bilateral symmetry and have a backbone while an Octopus has no backbone and shows 8 fold symmetry in part.
A cephalopod is a snail.
I think you mean "cephalopod". A cephalopod is any member of the molluscan class Cephalopoda (which means "head-foot"). These exclusively marine animals (salt water only) are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles. Two examples of cephalopods are octopus and squid.
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.
