Animals that take warmth from the sun
Cold-blooded = warm in the sun, cool in the shade.
Say it like this: cold-blooded = the body is as warm or as cool as the place around it. Fish, reptiles, and amphibians take warmth from the sun. In the shade they cool down, so they move slowly when it is cold.
