The VNO plays an important role in feeding behavior in garter snakes (Halpern and Frumin, 1979). Lizards also appear to use their VNO for food detection. Examples are the scincid lizard Chalcides ocellatus Gnves and Halpern, 1990) and the desert iguana D. dorsalis (Cooper and Alberts, 1991). The latter... 

When the weather is warm, marine iguanas can get too hot, so they also take precautions to cool themselves. One cooling technique is to position their bodies so that only a minimum of surface is exposed to full sunlight. The lizards also lift their bodies to allow cool air to circulate beneath them, creating a cooling breeze. If this technique is not enough to reduce their body temperatures, they can always retreat to shady areas between cracks in rocks. 

Marine lizards usually have ample food, but certain conditions can reduce the availability of algae. In the past, El Nino phenomenon, which causes ocean water around the Galapagos Islands to warm, has killed the algae species that the marine iguana eats. The only algae that survived the event were brown algae, which are toxic to marine iguanas, so many lizards died. El Nino is not a yearly event, however, and in most years lizards feed safely. 

Vertebrates who live along the oceans shores include several species of fish, birds, and mammals and one species of reptiles. The only shore reptile is the marine iguana, a lizard found only on the Galapagos Islands. Unlike terrestrial iguanas, this species is adapted to life on the edge of the sea where it feeds on intertidal algae. To dine, the lizard must dive into cold, wave-tossed ocean water and scrape the microscopic plants from rocks. Intertidal life is rough for this reptile, but its adaptations have enabled it to be successful in an environment in which no other reptile can survive.
