Across the Sunshine State, a cold wave pushing temperatures into the 40s or below left exotic fauna shivering.
More than 200 manatees lolled in 70 degree waters in a canal outside a Tampa Bay area power plant Thursday as crowds gawked on a viewing platform. Along with the sea cows, giant eagle rays and spinner sharks sought refuge in the warm waters.
"This is a spa for them," said Wendy Anastasiou, an environmental specialist for the Tampa Electric Co.
The manatees, many of which congregate near power plant outflows and natural-fed springs in the Tampa Bay area, weren't in immediate danger as they huddled near the Big Bend Power Plant in Apollo Beach.
Anastasiou said it's typical for the vegetarian mammals to seek warmer water when Tampa Bay waters dip below 68 F in winter.
During cold spells, the animals congregate in massive numbers, and gawkers "oohed" and "aahed" Thursday as the gentle giants - some weighing 3,000 pounds - occasionally surfaced.
"This is amazing," said Sharon Carpenter of Pinellas Park, who visited Tampa Electric's Big Bend Power Station on Thursday.
She wasn't so impressed with the forecast, which didn't discount flurries for parts of the state.
"I don't like it at all," said the Ohio retiree. "I dreamt about snow last night."
Across Florida, animals coped with temperatures that plunged way below normal.
Iguanas were seen falling out of trees in South Florida. The tree-hugging reptiles become immobilized in the cold weather shutting down everything but their hearts, causing them to lose their grip, reports CBS News correspondent Don Teague. Iguanas are not native to Florida; many are pets, or descendants of pets that were released into the wild.
Along Florida's Atlantic Coast, 93 sea turtles were found floating in a lagoon and experts said the cold water shocked their tropically inclined systems. Most were endangered green sea turtles and had to be sent to research facilities for care.
"We try to collect them and get them to a warm location," said Roger Pszonowsky, a volunteer with the Sea Turtle Preservation Society in Brevard County.
Freshwater turtles can go into mud and hibernate, he said, but sea turtles don't have that advantage and suffer from what he called "cold stunning."
And it wasn't just wild animals in Florida that needed warmth.
At the Palm Beach Zoo, workers sent 50 parrots and some monkeys indoors. They also set up heat lamps around the park to ward off the chill for other animals.
