Reptiles are ectothermic.
They rely on the environment to control their temperature.
Skin is thin and rough
Watertight, allowing them to live on land
Scales and Scutes (same function as scales but formed from the living dermis, rather than the epidermis)
All of a reptile’s teeth are the same shape
Infrared Sensing Organs
Insectivores or carnivores
Short and comparatively simple digestive tract
Slower than mammals
Because of the lower energy requirement of reptiles, they can digest slowly. A crocodile can live for months on a single meal
Most 3 chambered ( 2 atria and 1 ventricle)
Crocodiles have 4 chambers
Most sexual reproduction (some asexual)
Type of Birth
Most are oviparous
Leathery or calcareous shells
Some also viviparous and oviviparous
Swimming, slithering walking
Toxic bacteria in mouth
