Weather Tidbits: Falling Iguanas & Cold Weather

This Weather Tidbits explains why iguanas fall from trees in cold weather. Iguanas are cold-blooded animals that can’t produce their own body heat; that rely on the environment to regulate their body temperature. When temperatures are in the low 50s; most iguanas will have few affects. You may notice an iguana becoming sluggish; when temperatures drop into the upper 40s. They may become stunned, in the low 40s. Once the thermometer drops into the upper 30s, they are unable to move. The stunned state is the body’s way to protect themselves; until the temperatures warm up with their critical body functions operating & still breathing. The size of the iguana does play a role of when this dormant state occurs; with bigger ones lasting longer in the colder than smaller ones.
