Cold-Blooded Animals
Cold-Blooded Animals
Name:

A cold-blooded animal has no way to regulate it's body temperature and keep it constant as we do. A cold-blooded animal like a fish, depends on it's surroundings to regulate it's body temperature. A fish living in warm, tropical waters has a warmer body temperature than a fish living in the Arctic. A lizard sunning itself on a rock is trying to increase it's body temperature to in turn increase it's metabolic rate. A desert tortoise hibernates during the winter months because of colder temperatures and a slowing of its metabolic functions.
