Sharks and fish come from the same family. They are similar because both sharks and fish lay eggs to reproduce. Both cannot survive outside water and breathe through gills. They are both vertebrates and have fins as their locomotory organ They both have swim bladders too.

Sharks differ from other fish as they have no bones, only cartilage.

They also do not have a swim bladder like bony fish, just an oily liver to aid in buoyancy.

Sharks also lack the ability to swim backward like other fish and they have no gill cover.

Unlike bony fish, sharks (which are cartilagenous) lack a swim bladder. Instead, they have very large livers that aid in buoyancy (due to the oil), and most sharks swim continuously to avoid sinking.
