How does a marine iguana maintain homeostasis despite ingesting large amounts of salt with its food?
Marine iguanas sneeze excess salt out of their bodies
Marine iguanas pass large amounts of salt through their urine
Marine iguanas throw up large amounts of salt
Marine iguanas sweat a lot to get rid of the extra salt
Marine iguanas maintain homeostasis despite ingesting large amounts of salt with their food by sneezing excess salt out of their bodies.
Marine iguanas have specialized glands located in their nasal passages that help excrete excess salt. These glands produce a concentrated brine solution that is excreted through their nostrils when they sneeze. This sneezing behavior allows them to expel the excess salt and maintain a balanced internal salt concentration.
