Some reptiles prefer mud over dry habitat during extremely hot seasons. To determine if there is a difference in reptiles preference for mud habitat, researchers used a choice test, set-up in a Y-maze system. This system allows organisms to choose between mud and dry habitat by allowing them to move down the passage towards the habitat of their choice. A reptile choosing mud was regarded as a success. In this experiment, 20 specimens of each reptile type (namely: turtles, tortoises and crocodiles) were used in the trial.
