What do cold blooded reptiles have to do?

Answer 1

to keep warm -

cold-blooded reptiles often bask in the sun and expose as much skin as possible to the heat source (i.e the sun, heating lamp etc.). many reptiles are often capable of darkening their skin tone a certain degree to help the absorption of the heat.

to keep cool -

many reptiles will seek out shaded areas, open mouth wide (help to reduce heat inside of body), lighten in colour, and some may possibly burrow into soil/water.

during winter months many cold blooded reptiles will hibernate - putting their body into a stake of decreased metabolic activity. this is almost like a deep sleep lasting for months and this decreases the energy needed to operate the body ad allowing the reptile to survive prolonged cold spells.

some reptiles will also move underground to escape extreme temperatures and honeybees are known to group together and vibrate wings to keep warm during cold spells

Answer 2

Animals that are cold blooded means their core body temperature can be much lower than that of warmblooded animals.

Answer 3

Cold blooded animals maintain their temperature by getting in the sun or getting on warm rocks.
