Snakes Of New York

New York state is home to 17 species of snakes. These animals, whose tubular, limbless bodies are instantly and universally recognized, produce mixed reactions among people, from fear to fascination. Serpents figure prominently in the mythologies of nearly all human cultures, sometimes as a symbol of evil and temptation. It is perhaps for this reason that snakes often are persecuted and killed without any understanding of their true nature.

Snakes play critical roles in the environments where they occur, primarily by the position they hold in food webs in natural communities. Many snakes are top level predators; for example, a single rat snake can consume over 100 rodents a year.

Other snakes are important in the control they exert on insect and other invertebrate populations. All snakes form part of the diet of other predators such as hawks and foxes and thereby serve to link higher and lower feeding levels.

Common Snakes of New York

The most widespread and frequently encountered snakes in New York state are the garter snake and the water snake. Garter snakes use a wide variety of habitats, from woodlands to marshes to fields and exist quite well around human habitations. These snakes, like many other species, are variable in color and pattern; the basic color is dark brown or green with three yellowish stripes down their sides and back. They may reach lengths of two feet, but are typically smaller. They are completely harmless to people.

The water snake is found in and around almost any waterbody or wetland in the state. As an adult, it is a stout animal typically dark brown to black with lighter-colored bands and splotches along its length. This is most pronounced in young individuals (adults may appear solid black). It is the only large (up to 42 inches) water snake in our range. This species is frequently called or mistaken for a cottonmouth (water moccasin); this latter species is a large venomous snake that does not occur within our state borders. This confusion is understandable as our water snake is certainly an aggressive species with a nasty disposition and it does bear a superficial resemblance to the cottonmouth.

The milk snake has given rise to more misconceptions than perhaps any other species. Its name is derived from the decidedly false belief that it will milk cows! It is, however, frequently encountered in barns in search of its rodent prey (it also eats other snakes). The milk snake is a boldly patterned serpent (brown or reddish blotches on a light grey to tan body) that vibrates its tail when annoyed. These characteristics are undoubtedly responsible for its being called "spotted adder" in some regions, an unfortunate name because it brings to mind the truly venomous snakes of Europe and Asia. The milk snake is harmless.

The largest species in New York is the black rat snake, reaching lengths of eight feet! These largely black-colored snakes are found primarily along cliffs and rocky slopes but are absent from most of the Adirondacks. It is an impressive animal that overpowers its bird and small mammal prey by constriction.

Other kinds that occur all across New York in appropriate habitat are the green, redbelly, brown, and ringneck snakes; all four of these are small, slender, and completely benign species that feed on insects, spiders, earthworms and slugs. Each is described quite well by their common names.

Venomous Snakes in New York

Distribution and IdentificationThere are only three species of venomous snakes living in the wilds of New York (many other kinds may be found in the homes of private individuals and, occasionally, escapes occur!). These are the timber rattlesnake, the massasauga (erroneously called "pygmy rattler"), and the copperhead. All three are uncommon. The timber rattlesnake (listed as "Threatened" by the New York State Department of Environmental Conservation) enjoys the widest range; it is found mainly in the southeastern part of the state, except Long Island and New York City, with scattered populations as far north as Lake George and also along the Southern Tier in western New York. Its populations have been severely reduced, primarily due to bounties and commercial capture for snakeskin products and the pet trade. The massasauga (listed as "Endangered") occurs in only two locations, both large wetlands. One is located northeast of Syracuse and the other is west of Rochester. This species is the subject of a cooperative research program between researchers at SUNY-ESF and NYSDEC. The copperhead is mainly found along the lower Hudson Valley south of Kingston and scattered through the Catskills.

The timber rattler and massasauga both possess a rattle at the end of their tails. It is made of a series of hollow scales that produce a distinct buzz when the snake vibrates its tail (a new one is added each time the snake sheds its skin, which may be several times a year). Both rattlers are sort of chunky snakes but the timber rattlesnake can attain lengths of up to six feet while the massasauga barely reaches three feet. A timber rattler's head is much wider than a massasauga's and there are numerous small scales on the crown of its head; the massasauga has nine larger scales on the crown. Copperheads lack the rattle, but will vibrate their tail when annoyed. In dry leaves, this vibration can sound like a rattle; many other species, such as milk and rat snakes, will also perform this behavior. The copperhead can be told by its coppery-red head and by the distinct bands along its body which are widest at the sides and narrowest across the back.

Venomous snakes are best left alone. None of our species are particularly aggressive animals, but they will attempt to bite when handled.

Longest Snake Species In The US Released In Florida Preserve

Dozens of snakes were returned to their native Florida habitat in an effort to bring back the area's natural balance.

A total of 41 eastern indigo snakes, the longest snake species in the US, were returned to nature by researchers at the 8th annual Eastern indigo snake release.

The reptiles were deposited at the Apalachicola Bluffs and Ravines Preserve in Bristol, Florida, play "a vital role in the circle of life here," James Bogan Jr., the director of Central Florida Zoo's Orianne Center for Indigo Conservation, told the Miami Herald.

Eastern indigo snakes, which are native to the southeast US, eat venomous and nonvenomous snakes, as well as other wildlife.

The predators help to balance the ecosystem.

The snakes measure 5 to 7 feet in length, but some are known to reach over 8 feet.

The two-year-old snakes were all bred by the Orianne Center, the only captive breeding facility for the species.  

The species balances out the ecosystem. Central Florida Zoo & Botanical Gardens In total, 167 snakes have been released at the Apalachicola Bluffs and Ravines Preserve over the years.

The April 30 event marked the largest release of the species in one year, the zoo said.

In total, 167 snakes have been released at the preserve since the effort began.

"It is wonderful to see these young indigos have the opportunity to fill their important role as a lynchpin species in the longleaf pine ecosystem," Bogan said.


Eastern Coral Snake

Common Name: Eastern Coral Snake Scientific Name: Micrurus fulvius Average Life Span In Captivity: Up to 7 years Size relative to a 6-ft man: IUCN Red List Status:? Least concern

Least Concern Extinct

Current Population Trend: Stable

A bite from the notoriously venomous eastern coral snake at first seems anticlimactic.

Venom

There is little or no pain or swelling at the site of the bite, and other symptoms can be delayed for 12 hours. However, if untreated by antivenin, the neurotoxin begins to disrupt the connections between the brain and the muscles, causing slurred speech, double vision, and muscular paralysis, eventually ending in respiratory or cardiac failure.

This iconic snake, with its bulbous head and red, yellow, and black bands, is famous as much for its potent venom as for the many rhymes—"Red and yellow, kill a fellow; red and black, friend of Jack"—penned to distinguish it from similarly patterned, nonvenomous copycats, such as the scarlet king snake.

Behavior and Habitat

Coral snakes are extremely reclusive and generally bite humans only when handled or stepped on. They must literally chew on their victim to inject their venom fully, so most bites to humans don't result in death. In fact, no deaths from coral snake bites have been reported in the U.S. Since an antivenin was released in 1967.

Eastern coral snakes are relatives of the cobra, mamba, and sea snake. They live in the wooded, sandy, and marshy areas of the southeastern United States, and spend most of their lives burrowed underground or in leaf piles.

They eat lizards, frogs, and smaller snakes, including other coral snakes. Baby snakes emerge from their eggs 7 inches long and fully venomous. Adults reach about 2 feet in length. Average lifespan in the wild is unknown, but they can live up to seven years in captivity.
