What do Cephalopods eat?
Sharks eat cephalopods
I believe you're referring to a structure called a Radula.
Cephalopods use their tentacles mainly to catch food.
Vampire squids are small, deep-sea cephalopods. They are found in tropical oceans all over the world. They prefer a warm, temperate climate.
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.

The chambered nautilus has more primitive eyes than some other cephalopods; the eye has no lens and thus is comparable to a pinhole camera. The species has about 90 tentacles with no suckers, which is also different from other cephalopods. Chambered nautiluses have a pair of rhinophores, which detect chemicals, and use olfaction and chemotaxis in order to find their food... -wikipedia
Bivalves, univalves, and cephalopods are all types of mollusks. So are gastropods.
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.
