Crab

A red crab, often a king crab or Dungeness crab, with prominent claws, facing forward or to the side.

The 🦀 crab emoji represents the crustacean and is used in discussions about marine life, seafood, or the beach. It's a symbol of the astrological sign Cancer. In a metaphorical sense, the emoji can be used to describe someone who is "crabby" or irritable, or to represent a feeling of being defensive or protective, much like a crab's hard shell. It can also be used to describe a sideways or indirect movement. It's a versatile emoji that can be used for everything from talking about a delicious meal to describing a mood or a personality trait.
