NMNH Virtual Tour - Reptiles and Amphibians Preserved reptiles and amphibians await you around every corner in this hall. Learn about their eating habits, defenses, and locomotion. Reptiles on display include Galapagos marine iguanas, sea turtles, snakes, crocodiles, and lizards.
Reptiles have dry, scaly skin and lay shelled eggs in dry locations.
Their embryos usually develop inside the egg or within the parent. The young resemble miniature adults. Amphibians, such as frogs and salamanders, have moist skin, no scales, and lay gelatinous-covered eggs in moist areas. Their tadpoles are free-living embryos. They must complete development while avoiding predators and searching for food.
