Ohhhhh, good catch, Sophie!

Gorgeous pictures! Love the oversized head on the first pic. Yes, definitely a juvie cottonmouth (water moccasin). The juveniles do the mouth display, but the snakes only do the display when they feel threatened or cornered. Different individual snakes have different thresholds for feeling threatened and different individual humans have different behaviors that can prompt or avoid a snake going into a defensive or aggressive response. Since you control the human behavior side of the equation you probably did a good job of not provoking the snake.

Looks more like a copperhead.
From the venomoussnakes.net website;

Appearance

The snake, with by the way has the Latin name Agkistrodon contortrix, has dark colored bands of varying width across most of its body except for the tip of their tails, which may look almost greenish or yellowish.

It can reach a size of 40 inches (1.05 meter) but the normal size of the Copperhead is in the range 24 to 36 inches (61-91 cm).

...the Florida Cottonmouth. Nice pic; All of its field-marks show well.

Eliptic(cat's) eye, triangular shaped head, pit viper. Definitely poisonous.

Nice pics.

Hey, thanks ever so, y'all! I was fairly sure it was a baby moc, but snakes are not my forte.

It must have been the mellowest moccasin ever, coz he didn't act very aggressive even when I used a LONG stick to try to get him off the road. Unlike the corn snake a while back that made it quite clear he was not going to put up with being evicted from HIS road.

How's about some dragonfly pics, Sophie? I miss all my Florida pals.

Yep thats a cotton mouth. How did you catch that thing?

AnimalGal, my 18x zoom comes in REAL handy when I come across venomous critters. 8-]
Unless it's a diamondback, I always try to find a long stick to coax them off the road, coz the next person is fairly likely to run them over.

I found a baby snake in my pool today and the top of him is blackish and the belly is like a yellow with black stripes all the way down the tail and I was wondering if this is a baby cotton mouth or something else please help it looks like a hatchling so the mother must be around as well as more babies and I have my 2 gradkids that live with me and I want to be aware of what comes in the pool thank you

sounds much more like a garter snake....

The snake is a baby Cottonmouth, not a Copperhead; Copperheads aren't found in FL, except for a tiny area around Tallahassee. Plus, the bands are wrong for a Copperhead.

Donna,

Your snake doesn't sound like a baby cottonmouth. A baby cottonmouth would look like the one in the picture at the top of this thread.
