Cold weather in the last week left some frozen stiff.
Iguanas in South Florida did not fair well when the temperatures fell below 40 degrees.
Experts said the reptiles' bodies shut down ,and iguanas were literally falling from trees, onto the ground.
Tim Stallings of Pompano Beach said he felt bad and tried to help keep some iguanas warm in his car.
"They were frozen stiff -- I mean, that's the appearance they have," Stallings said. "I just started picking them up and putting them in the truck, put the heater on. Some of them came back, and some of them didn't make it."
Stallings has tried to help the iguanas before. He saved about 30 during a previous cold snap.
