Do you love big bluegill?
Texas River Snake
After looking at the pictures again I can tell that there are two species here:
1. Broad-Banded Watersnake 2. Brown Watersnake
I would not say aggressive but defensive. The opening of the mouth to expose the white lining is the cottonmoths` defesene mechanism; just like bluegill go into thick coontail when a large-mouth bass swims near.
It was not telling Dean to come closer. It was telling Dean that "hey please dont step on me! I can bite you, but I don`t want to."
By the way if you would like to learn more about cottonmouths go to the link I gave you. Also in Texas, the species of cottonmouth is the Western Cottonmouth Agkistrodon piscivorus leucostoma.
I hope I have helped.
Every1 know what kind of snake this is. Walking toward the water didn't pay no mind that there was a snake right in front of me.
Could it be a Milk Snake, or maybe a King?
Yellow bellied water snake
Still, I like snakes. They feed on the small things, the basic, intermediate links within the chain.
When I see a snake, it tells me the order of things is, well... in order.
PS Venomous snakes, of course, get a wide berth. They dont scare me, but respect is respect.
