Unusually cold weather in Florida has made life uncomfortable for many animals. Florida Fish and Wildlife says it has rescued over 200 cold-stunned sea turtles throughout the state this week. /VCG Photo

When the temperature drops drastically, stunned sea turtles may float listlessly in the water or near the shore. /VCG Photo

Veterinarians say that when sea turtles become inactive in cold water, they may easily be hit by boats and injured. Their immune systems may also be damaged,  leaving them susceptible to infections like pneumonia. /VCG Photo

Temperatures dipped below four degrees Celsius early Thursday in parts of South Florida, which has a tropical climate. Iguanas are reported to have fallen from trees as a result of the rare cold spell. /VCG Photo
