Why do low temperatures cause a rain of iguanas in Florida?

A cold snap, accompanied by icy winds, caused thermometers in Miami (USA) registered minimum marks, like 47 degrees Fahrenheit (8.3 degrees Celsius) last morning, and that Miamians had to take out the outerwear they hardly ever need to wear.

However, beyond the typical consequences of the cold, there is one that continues to surprise the citizens of Florida every time this time of year arrives. Is about the rain of iguanas.

These reptiles are part of the usual fauna of this state due to its high temperatures, although with the arrival of winter, these can drop drastically until the arrival of spring.

When winter comes, the iguanas ‘freeze’, that is, they are ectothermic animals (its temperature depends on the ambient temperature). Therefore, when the intense cold begins, the lack of blood flow makes them very slow, to the point of becoming completely immobile.

How does the cold affect iguanas?

They are found mainly on the branches of trees resting, but the cold causes them to become paralyzed and fall to the ground due to their inability to move. These months are your period of hibernation and is commonly known as ‘iguana rain’.

Even though they’re paralyzed on the ground, it is dangerous for citizens to approach too much to them because they are still alive and could bite. It is frequent that on these dates the media warn of this.
