Question

Fish within the same species live in a lake together. They range in color, being dull green, brown, or bright blue. The dull green and brown fish are able to blend in with the algae at the bottom of the lake easily, whereas the blue fish have a hard time hiding from predators, given their color.

Which type of selection does this describe?

directional selection
