When the temperature falls below a certain level, the large green lizards drop out of the trees and litter the ground.They aren't dead. At least a lot of them aren't. It is as if they are in suspended animation, said Robert Yero, park manager at Bill Baggs Cape Florida State Park on Key Biscayne.
It was raining iguanas at Bill Baggs Thursday morning. There were a couple underneath buttonwood trees and a third beneath a sea grape. All were about 30 yards from the beach, in the coastal hammock.
''We have found dozens on the bike path after a major cold snap,'' said Yero. ``When they warm up in the sun, they come back to life.''
Yero isn't too fond of the comatose critters. They are exotics from Central and South America, brought in as pets and then released to the wilds by their owners when they got too big for the house.
They munch on the foliage, literally nipping in the bud efforts to revive native vegetation.
''They really are taking over,'' Yero said.
