Reptiles and amphibians share two similar traits: They both lay eggs and they are unable to regulate heat with their own bodies and must warm up basking in the sun or cool off by seeking shade. Currently there are more than 10,000 species of reptiles with an additional 2,700 subspecies and more than 6,000 amphibian species exist worldwide.
Reptiles include lizards, snakes and turtles. Reptile eggs have hard shells to prevent water loss which enables them to lay their eggs on land. Their skin is scaly which allow them to thrive in hot, dry climate of deserts.
Amphibians includes frogs, salamanders and toads. Amphibians lay their eggs in water and start their life with gills then convert to air-breathing when they become adults. They have thin delicate skin and cannot survive far from water or moist woodlands.
Virtually all of my reptile and amphibian sightings are incidental sightings which means that have only seen reptiles and amphibians when I was involved in some other activity.
