The most obvious phenotypic change in response to the environment is the temperature-dependent determination of gender in red-eared slider turtles. Eggs incubated at a lower temperature are more likely to produce males, and those kept at the higher temperature are more likely to become females. Another example would be differing diets in moth larvae that biochemically change the morphology of the developing larvae so that they camouflage more effectively in whichever environment they grow up in.
