I went out this morning to skim the pool and check the chlorine levels. I am used to finding frogs, sometimes lizards and an occasional snake and sometimes a lone crab or crawdad. This morning my pool was full of these little buggers! One male and a bunch of females. I think they are fiddler crabs and I think they were having a party in my pool! It took an hour to scoop them all out, one at a time and they are fast! They didn't want to be caught.
The resaca(water, like a slow moving river) is about 200 ft from the pool, did they crawl all that way just to go for a midnight swim?
