It’s not the alligators. These are the ones that worry me.
…Agkistrodon piscivorus is a venomous snake, a species of pit viper, found in the southeastern United States. Adults are large and capable of delivering a painful and potentially fatal bite. When antagonized, they stand their ground by coiling their bodies and displaying their fangs. Although their aggression has been exaggerated, individuals may bite when feeling threatened or being handled. This is the world’s only semiaquatic viper, usually found in or near water, particularly in slow-moving and shallow lakes, streams, swamps, and marshes (Wikipedia).
We don’t see them very often and they tend to hide where you would never, ever, walk. Like an alligator if they have been in the water all the small weeds will cling to their scales making them invisible.
