Nerodia rhombifera
The Diamond-back (or backed) Water Snake is a long, heavy-bodied, tan to gray-brown snake with a pattern of dark brown to black chain-like markings. The belly is yellow, but with dusky brown markings. As the name implies it lives in slow moving waters and is found all over Louisiana. These beautiful snakes eat fish, frogs, and a few birds.
The Diamondback Water Snake
is a beautifully patterned non-poisonous snake. The almost triangular shape of it's head can be deceiving to the novice and it is often confused with water moccasins. It's round eyes, lack of pits above the eyes and long, thinner tail distinguish it from the venomous Cottonmouth Moccasin.
Diamondbacked Water Snakes in our Habitat
Since our wildlife habitat is located along the Tchefuncte River, we often see many water snakes, but the largest and most interesting one that lives around the river is the Diamondback Water Snake. This snake can grow to 63 inches and we have several this size. They mate in the spring and have live young from early August to late October.
We have been lucky enough to photograph this attractive snake both in and out of the water. They like to bask in the sun on over hanging branches or cling to a submerged branch to lie in wait while hunting. Where we live, these skillful hunters eat primarily fish and we have observed one grab a 2 pound catfish and take it to the shore to eat it. The snake worked to try to swallow the fish for hours, until it finally gave up and tried for a perch.
Unfortunately, this beautiful, non-poisonous snake is sometimes killed because of its slightly triangular head, the untrained mistake it for the venomous Copperhead or Water Moccasin. The photos below (from "The Amphibians and Reptiles of Louisiana" by Harold A. Dundee and Douglas A Rossman) show the difference between the heads of the snakes.

Diamond-back Water Snake Sunning on a Log
Since snakes are cold-blooded, they must take advantage of the sun to warm their bodies. That is why you will often see them stretched out on logs or curled in tree branches "sunning". We photographed this large Diamond-back Watersnake, near the Tchefuncte River, sunning on a tree that was downed during Hurricane Katrina.

I try not to think about them.
Diamond-back Watersnake "Fishing"
Some watersnakes hook their tails to a submerged branch and lie in wait for their prey. Here is a shot of a Diamond-back Water Snake "fishing" in the Tchefuncte River. We have observed Diamond-back's grabbing fish underwater many times. It looks strange, because, in most cases, you don't see the snake, you just see the fish as the snake whips it around in the water.

Diamond-back hooked its tail around a branch & is very still with its nostrils out of the water.

Snake Facts from Wiki
Snakes are elongate legless carnivorous reptiles of the suborder Serpentes that can be distinguished from legless lizards by their lack of eyelids and external ears. Like all squamates, snakes are ectothermic amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with many more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. In order to accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca.
Living snakes are found on every continent except Antarctica and most islands. Fifteen families are currently recognized comprising 456 genera and over 2,900 species.Colubridae species list at the TIGR Reptile Database. Accessed 4 December 2008. They range in size from the tiny, 10Â cm long thread snake to pythons and anacondas of up to in length. The recently discovered fossil Titanoboa was long. Snakes are thought to have evolved from either burrowing or aquatic lizards during the Cretaceous period (c 150 Ma). The diversity of modern snakes appeared during the Paleocene period (c 66 to 56 Ma).
Most species are non-venomous and those that have venom use it primarily to kill and subdue prey rather than self-defense. Some possess venom potent enough to cause painful injury or death to humans. Those which are non-venomous either swallow prey alive or kill it via constriction.
