Some do, some don't. Humans, cats, birds, fish and a thousand other species have skeletons within their bodies. Beetles, flies, and insects have skeletons outside their bodies (exoskeletons). But animals like worms and octopus and amoeba don't have any skeletons at all.

No. Fish ARE Chordates, but they include BOTH Cartilaginous AND Bony flavors. (Sharks, Rays, Skates, Chimaeras, etc. are ALL FISH and ALL have cartilaginous skeletons).
