Why don't crabs share?

Because they're shellfish.

Why This Joke Works

"Shellfish" sounds like "selfish" — and crabs are literally shellfish (crustaceans with shells). They don't share because they're selfish, and they're selfish because they're shellfish. The wordplay is phonetically near-perfect, and the personality trait fits the animal category so well it feels like destiny.

🎤 How to Tell This Joke

Ask the setup with mild frustration, like you've personally tried to get a crab to share and failed. Say "shellfish" with an accusatory tone.

Perfect for:

  • seafood restaurants when crab is on the menu
  • when someone won't share their food
  • beach trips where you spot crabs in tide pools

💡 Did You Know?
