HI,
I looked it up.
Manatees gather in warm / hot springs or near power plants that turn on heat for them. The manatees need a minimum temp of 61 degrees to survive.
Iguanas can't make it if the temp stays below 40 for two or three days. We have had cool nights near 40 below for what seems like a week but the days have been warmer than that. The iguanas are an invasive species and are cute in an ugly way but are also considered pests.
Sea turtles become immobilized when the temp is 60F. They bob to the surface of the water. They can go into shock and get pneumonia. Some turtles have been rescued and are getting treatment.
Alligators can hibernate in "dens" during cold season. They keep their noses above the water.
I didn't feel like looking up
snakes. They seem like a primitive species that can survive with out my attention.

Oranges were picked in most places before the weather came in. Oranges can survive a night or two of cold temps. Most areas were expected to be ok last I heard.
Strawberries,
tomatoes, and others, are still threatened, depending on future weather I think.
