Crab races are fun events where participants bet on crabs to see which one will reach the finish line first. Typically held at fairs or festivals, these races feature small crabs placed in a circular arena. Spectators cheer for their chosen crab as they scuttle around, creating an exciting atmosphere. The crabs used in these races are often hermit crabs or blue crabs, known for their quick movements. Organizers usually provide a set of rules, and the winning crab can earn prizes for its owner. Crab races are a lighthearted way to engage the community and enjoy a day of entertainment.
