In our swimming pool we haven't found much flora and fauna. Our back yard is surrounded by a cinderblock fence, so not much gets in or out. Lizards live on the wall and in the rock garden, and when it was hatching season for the baby lizards I was finding them everywhere, from my swim-robe tha I left on the deck of the pool while I swam to the skimmer. They were everywhere. most lizards I've found in my pool have been fine if rescued soon enough. Our pool is the "saltwater" variety that uses chlorine and salt water for a self-regulating environment. We even have water beetles that have moved in. ?
In addition to lizards, we once found one of my escaped hatchlings. Hubby found it in the pool and I was concerned that she wouldn't make it. She fed but shortly thereafter did die. We let the bugs skeletonize her and I saw what killed her. While she was away she'd been nabbed by a bird or a cat, and had about ten broken "ribs" ... one probably perforated something while she ate, killing her. caught a kitten in the pool once.
that one didn't make it. Occasionally one of the neighborhood cats goes racing by the pool and misjudges the distance, plummeting into the water.
I would NEVER take my snake for a swim in the swimming pool or the hot tub (especially the hot tub)... Might be bad for the snake, but I can just imagine a big ol Boa letting loose a big turd in my lovely water. EEEWWW!
