Preview

This chapter is concerned with electrolyte regulation in herbivorous reptiles, especially those living in marine and intertidal habitats. It discusses the distribution of salt glands among the lizard taxa and the extent to which different species can modify their sodium and potassium secretion. Modification of salt secretion may give lizards flexibility in acclimating or adapting to changes in dietary salinity. The chapter also examines other aspects of salt secretion that might be important for marine lizard evolution.

Keywords: electrolyte regulation; salt glands; lizard; sodium secretion; potassium secretion; salt secretion; dietary salinity
