Beautiful, but don’t touch. This is the world’s only semi-aquatic viper. They will grow to be 26 – 35 inches (65 – 90 cm), in the eastern US they can be up to 71 inches (180 cm).
Although poisonous, deaths are rare, however bites can leave scars, and on occasion, require amputation. Again, don’t touch.
This snake was in a very large and flowing swamp. The underwater palm gave him a place to rest.
I was not very close (see above) so actual size is hard to guess. It was probably medium size, maybe 3 feet.
The Cottonmouth has been the most common snake we see when out. It might have something to do with walking in swamps often, however I had thought other species would be more common.
Actually I would prefer other species be more common.
