Spinney fence lizards are found Jamaica and feed on medium-size land snails by crushing them with moderate size jaws. Blue-tongued skinks (another lizard species) are found in Australia and also feed on medium-size land snails by crushing them with moderate size jaws. When both of these lizard species are found in the same snail-infested pastures in Japan, spinney fence lizards use narrow jaws to pull the snail bodies out of small and medium shells, and blue-tongued skinks use heavy jaws to crush medium and large shells. This is possibly an example of:. A. Interference competition
B. Exploitative competition
C. Character displacement
D. Resource partitioning
E. Mutualism
