warm-bloodedness


Not to be outdone by the turtle, the first bullfrog of the season appeared at Ijams Nature Center three days ago as well. Shelia spotted it tucked away by the plaza pond soaking up some sun.

Being ectothermic has its advantages. WE warm-blooded mammals must find food often just to keep our body temperatures constant. The ambient air temperature controls the body temperature of reptiles, amphibians and insects, so they do not need to eat nearly as much. They don't even have to eat daily.

If we were cold-blooded, we'd sleep through winter and most restaurants would have to go out of business. If you own an eatery, you should post a sign in your window declaring it “Warm-bloodedness Appreciation Day."
