Yep, they are found throughout the tropics and subtropics. The ones I've seen in the Sea of Cortez and Florida live in mangroves.
You can read further about the North American ones in my newspaper column on them.
Very interesting critters!
By the way... nice pictures of them!
I've seen them in the mangroves in Key West as well...they remind of snowflakes.
