Here's a table summarizing the key differences:
| Feature | Whale Shark | Shark |
|---|---|---|
| Classification | Rhincodontidae | Selachimorpha (various families) |
| Feeding | Filter feeder | Predatory |
| Diet | Plankton, krill | Fish, squid, marine animals |
| Size | Largest fish, up to 40 feet | Varies widely, from <1 foot to 20 feet |
| Appearance | Spotted pattern | Diverse, depending on species |
In short: Whale sharks are filter feeders, while most sharks are predatory. Whale sharks are the largest fish in the world, while sharks come in a range of sizes. While whale sharks are more closely related to other sharks, they are distinct enough to be classified in their own family.
