"Marine iguana (Amblyrhynchus cristatus). Like other ectothermal reptiles, the marine iguana must regulate its own body temperature: as soon as the sun rises, it lies flat, warming as much body area as possible until the temperature reaches 95.9° Fahrenheit (35.5° Celsius); it then changes position to avoid overheating. The marine iguana needs a high body temperature in order to swim, to move about and to digest. Galápagos. Ecuador. January, February and March 2004."
