Unlike reptiles, birds are endothermic. They also have feathers, which conserve heat.
They have feathers to stay warm, and high metabolism (warm blood) so they can stay active.
They have hard keratinized skin.
Some characteristics of reptiles include having scaly skin, being cold-blooded, laying amniotic eggs, having a three-chambered heart, and being predominantly terrestrial. They also typically have claws, scales, and breathe with lungs. Reptiles have adapted to various environments and exhibit a wide range of sizes and physical features.
lungs, legs, and skin
lizards like all reptiles are cold blooded
It was an advantage because reptiles no longer had to stay near bodies of water and could live in more environments than amphibians.
well they have to be in a moist environment and wet mud to keep it from drying out.
Because frogs aren't reptiles, their amphibians. And frogs need moisture to keep their skin from breaking. Snakes and lizards are Reptiles, and do not require this need for moisture.
Reptiles prefer to live in warm, dry climates rather than wet ones. However, they can be found on every continent except for Antarctica. Reptiles have adapted to live in a variety of environments, including water, deserts, jungles, forests, and mountains.
they can travel over land because they do not need to lay eggs in water
Fur and a layer of fat beneath mammals skin enables mammals to live in colder environments than reptiles because the amount of fur that covers a mammal's skin varies greatly like animal that live in cold region have more fur than animal that live in warmer environments.hope this helps!!
In conclusion, animals can be classified into different groups based on various characteristics such as their body structure, feeding habits, and reproductive methods. The main classifications include mammals, birds, reptiles, amphibians, and fish. Each group has its own unique traits and adaptations that allow them to thrive in their respective environments.
