Brown water snake . We have one at our place . I just shoo him off the dock, or sit down when we are out . it's no danger no problem . I have seen him eat a few cat fish thats cool enough for me to keep him around. We are a semi snake friendly family .
In the picture below My wife was the one behind the camera. My son kept getting in the snakes face I mean inches . I wish I had a video . she told him " if that snake bites you in the face don't come crying to me " . Long and short if they are not poisonous don't kill them . He is just doing his job.
Miscellaneous: Like most other watersnakes, brown watersnakes are often mistakenly identified as cottonmouths and killed. When captured, these snakes, like other watersnakes, will bite repeatedly and emit a nasty smelling musk from their anal glands. Female brown watersnakes grow longer and much heavier than males. Although nonvenomous, the bite of a large, female brown watersnake can be quite painful.
