That's a southern toad she's consorting with here. Make sure there's no one using the facilities before you try this. Rarely seen, but always present, are bobcats. Their footprints and scat are commonly found on the dikes through the marsh habitats, and along the nature trails through hammocks. I've only seen bobcats on a couple of occasions, however, and then only briefly as they beat a quick retreat.
River otters are regular visitors of all the canals and impoundments.
They seem to hang out in one area for several days-weeks at a time, then move elsewhere. Opossums are abundant, but mainly nocturnal and not easily seen during the day. From spring through fall, and even in mid-winter on warmer evenings, bats are frequently observed foraging at dusk over the pools, impoundments, and around the parking lot. I wouldn't even hazard a guess as to what species they might be. This Seminole bat was found roosting in one of the hammocks, though.
