In addition to being ectothermic, reptiles are categorized as poikilotherms: animals whose body temperatures vary rather than remain stable. Reptiles have behavioral adaptations to help regulate body temperature, such as basking in sunny places to warm up and finding shady spots or going underground to cool down.
The advantage of ectothermy is that metabolic energy from food is not required to heat the body; therefore, reptiles can survive on about 10 percent of the calories required by a similarly-sized endotherm.
In cold weather, some reptiles, such as the garter snake, brumate. Brumation is similar to hibernation in that the animal becomes less active and can go for long periods without eating, but differs from hibernation in that brumating reptiles are not asleep or living off fat reserves.
Rather, their metabolism is slowed in response to cold temperatures; the animal becomes very sluggish. Learning Objectives Summarize the key adaptations of reptiles.

The Green Anaconda is the heaviest snake, while the Reticulated Python is the longest snake. The fastest reptile is the spiny tailed iguana which can run up to 20 miles per hour.
The fastest snake is the Black Mamba. Start your child on a learning programme today! Trial it for FREE today.
There are a few major differences between reptiles and amphibians. Amphibians go through a larval stage, like the tadpole which turns into a frog. Reptiles don't do this. Also, their skin is different: reptiles have scales for skin, but amphibians have moist, glandular skin. Reptile skin is covered with scales , structures that grow on the animal's outer skin and consist of a hard substance known as keratin which is similar to human hair and fingernails.
Scales are replaced every so often through a shedding process in which the entire skin is shed in one piece or flakes off in small pieces. Reptile scales vary in shape, size, texture and colour. Scales help prevent reptiles from losing water through their skin.
The leathery or hard shells on their eggs protect the young from drying out while they grow inside the egg. Most reptiles can live their entire lives on land. Some types of reptiles such as sea turtles are adapted to living in water, but even these species come onto land to lay their eggs.
All reptiles also have lungs, so even those living in water must come to the surface to breathe air. Reptiles are found living in all habitats but are more common in warm, tropical places. Fish and amphibians have evolved with skeletons. Reptiles have developed larger skeletons that can hold larger organs and help them increase in size.
