Summary
The teiid lizardAmeiva quadrilineata has a nasal salt gland that responds to NaCl loading by increasing excretion of Na+ (from 1.12 to 2.63 μM/100 gh), K+ (from 0.14 to 2.43 μM/100 gh), and Cl− (from 1.10 to 5.47 μM/100 gh). For salt-loaded lizards these values represent 47% of the total excretion of Na+, 35% for K+, and 87% for Cl−.
The lizards forage on beaches and their diet includes large numbers of amphipods (Talorchestia) which are approximately twice as salty as the lizards' body fluids. All of the ingested Na+ and K+ can be excreted through the cloaca, but extra-renal excretion of Cl− is probably important to the lizards under natural conditions.
