  5. Active Thermoregulator Ctenophorus isolepis

  6. Water Economy in Desert OrganismsOther Limiting MaterialsSensory Capacities and Environmental CuesAdaptive SuitesDesign Constraints

When fed dry grass, they become brown When fed moist grass, they become green Green-brown switch modulated by moisture content of food. Classic “Environmentally induced” polymorphism But, because it is clearly adaptive, it must be genetic Genes must underly what color a grasshopper becomes.
