The nephrons of Dipodomys have been mdified in order to increase reabsorption of water in the kidneys. In particular, Dipodomys have been shown to have significantly longer Loops of Henle than other rodents. (Howell & Gersh, 1935) Studies have shown that a measure of medulla thickness and medulla to cortical ratios are relatively much higher in kangaroo rats than in other mammals, showing that kangaroo rats have evolved longer Loops of Henle (Abdalla, 1979).
