The concept that reptiles and amphibians have cold blood is not always entirely accurate. Depending on the time of day and year, many reptiles commonly have blood temperatures higher than that of humans—being variable does not equate to always being cold. This is a relevant distinction from a scientific standpoint, but there is also a social component. The term cold-blooded has come to mean “unfeeling” or “creepy.” Indeed, “cold-blooded” is often used to refer to a person who is callous or vicious. Since reptiles are none of these things, and since public support is needed to increase conservation efforts, herps could benefit from us dispensing with this imprecise terminology. Herps are poikilothermic and ectothermic.
