# Great Scallop vs Pacific Oyster: Who Would Win?

Great Scallop vs Pacific Oyster is too close to call. Our 3-round simulation gives Great Scallop a 50% chance and Pacific Oyster 50%, which is not enough for either to claim the win.

The simulation puts both animals on neutral ground. In the wild, terrain, the size of the individual animals and plain luck would all change the result.

## Verdict: Too close to call
