All cephalopods (octopus, squid and cuttlefish) require saltwater of the proper temperature (species dependant), a suitable habitat (species dependant), and proper nutrition (fish and invertebrates).
What do Cephalopods eat?
Sharks eat cephalopods
Cephalopods use their tentacles mainly to catch food.
No, a shrimp is not a cephalopod. Shrimp belong to the class Crustacea, which are arthropods, while cephalopods, such as octopuses and squids, belong to the class Cephalopoda. The two groups differ significantly in anatomy, behavior, and habitat. Cephalopods are known for their intelligence and complex nervous systems, whereas shrimp are generally simpler in structure and behavior.
Nope. They are reptiles. Cephalopods are octopuses and squids and cuttlefish. Reptiles and cephalopods are not very closely related at all; cephalopods are protostomes and cephalopods are deuterostomes, and the protostome/deuterostome split occurred very early in the history of animalia.

No
Octopus, cuttlefish and squid are all cephalopods. http://en.wikipedia.org/wiki/Cephalopod
No. Squids and octopi are a class of mollusks called Cephalopods, and as with all mollusks, cephalopods are invertebrates.
Bivalves, univalves, and cephalopods are all types of mollusks. So are gastropods.
