A U.S. state is any one of the 50 federated states of the United States of America that share sovereignty with the federal government.

They also note historical use or economic benefits from the creature, and discuss how widespread the animal is in the state or how it needs preservation.

 would be a better representative. The turtle also drew scorn for often perishing on roads, but its most serious problem was a too-close association with bordering state, North Carolina.

Justification

Like other state symbols, a state reptile is intended to show state pride. The designation has no economic or wildlife protection effect. States justify their choice of state reptiles, with differing rationales, in designating legislation and on websites:
  • North Carolina selected the eastern box turtle because its behavior reflects admirable human ideals: "The turtle watches undisturbed as countless generations of faster 'hares' run by to quick oblivion, and is thus a model of patience for mankind, and a symbol of our State’s unrelenting pursuit of great and lofty goals."
  • Maryland notes its historical associations with the diamondback terrapin: "Chesapeake colonists ate terrapin prepared Native-American fashion, roasted whole in live coals. Abundant and easy to catch, terrapin were so ample that landowners often fed their slaves and indentured servants a staple diet of terrapin meat. Later, in the 19th century, the turtle was appreciated as gourmet food, especially in a stew laced with cream and sherry."
  • Ohio touts the ubiquity and practical benefits of its reptile: "The black racer
    Coluber constrictor
    Coluber constrictor is a species of nonvenomous, colubrid snakes commonly referred to as the eastern racers. They are primarily found throughout the United States, east of the Rocky Mountains, but they range north into Canada, and south into Mexico, Guatemala and Belize...

     snake was adopted because it is native to all 88 Ohio counties and is called the 'farmer's friend' because it eats disease-carrying rodents."
  • Texas stresses the conservation needs of the Texas horned lizard: "It is perhaps most appropriate for designation as an official state symbol because, like many other things truly Texan, it is a threatened species."

Use

The state reptile concept serves education. Some states offer lesson plans using the reptile for teachers to introduce children to the legislative process, discuss state geography, or develop state patriotism. Many Secretaries of State have a "kids page" describing the reptile. Some, such as Missouri's Robin Carnahan

Rate of adoption and comparison to other symbols

In 1969, Oklahoma designated the first state reptile when it chose the collared lizard. Two states followed suit in the 1970s, seven states in the 1980s, eight states in the 1990s, and eight states in the 2000s. As of January 2011, twenty-six of the fifty states have named a state reptile; none has yet been named in the 2010s.

In contrast to state reptiles, state birds have been more rapidly adopted, with the first state designating one in 1927 and the fiftieth in 1973. As of January 2011, other types of animals more popular for state symbolization were mammals (46), fish (45), and insects (42). Animal symbols less popular than reptiles were butterflies (17), amphibians (17), dogs (11), dinosaurs (5), bats
U.S. state bats
As of February, 2011, at least three US states had an official bat. The general assembly of North Carolina considered a bill in 2007 that would have made Rafinesque's Big-eared Bat its state bat. The bill passed 92-15, but died in the state senate....

In their almanac of U.S. state symbols, Benjamin and Barbara Shearer spend comparatively little text on state reptiles. They spend a full chapter each on state birds, trees and flowers; within those chapters, they take about a half page to describe the campaign to establish each state's specific symbol. Reptiles, on the other hand, are shown only in list format in a chapter titled "Miscellaneous", where the other non-bird animals (and many non-animals) are listed. Shearer and Shearer consider the state reptiles to be part of a "last thirty years" phenomenon (written in 2003) that includes such particular items as a state's "official beverage".

Politics

Some of the state reptiles have had previous appearances in American politics.

, recent scholarship asserts that the snake on that jack was a late 19th century invention. Nevertheless, in 1975 and 1776, the U.S. Navy brought back the traditional (snake-showing) jack for the service's bicentennial. After 1980, the oldest commissioned vessel in the U.S. Navy was designated to use the traditional jack. Since 2002, in response to the 9/11 terrorist attacks, the U.S. Navy has all its ships using the First Navy Jack.

West Virginia named the timber rattlesnake as its state reptile in 2008. A 2009 article, "West Virginia's state reptile", in the state wildlife magazine drew a connection to the older American rattlesnake symbol:

Actually, the warning on the early flags was not meant to depict the timber rattlesnake as being ferocious or the American people as being warlike. The true message was that the citizens of the Colonies were a peaceable and freedom-loving people, but if England’s King George III continued with his oppressive policies toward the Colonies, then they would respond with great wrath. This response would be much like that of a timber rattlesnake, which is peaceable and slow to anger, but will attack aggressively when provoked and will not stop fighting until the enemy retreats.



Benjamin Franklin, writing as an anonymous person, submitted the following statement concerning the disposition of the timber rattlesnake to the Pennsylvania Journal in 1775: “She never begins an attack, nor, when once engaged, ever surrenders: She is therefore an emblem of magnanimity and true courage...she never wounds ‘till she has generously given notice, even to her enemy, and cautioned him against the danger of treading on her."



In contrast to the positive symbology of the rattlesnake, some political use has been for criticism. The snapping turtle (New York) was the central feature of a famous American political cartoon. Published in 1808 in Federalist protest of the Jeffersonian Embargo Act of 1807
Embargo Act of 1807

, going from Extinct to Least Concern. None of the U.S. state reptiles are in the most extreme categories of Extinct, Extinct in the Wild, or Critically Endangered. Two species are IUCN Endangered: the Alabama red-bellied turtle (Alabama) and the loggerhead sea turtle (South Carolina, also the state saltwater reptile of Florida). However, in the United States, only the Alabama red-bellied turtle is legally an endangered species
Endangered Species Act
The Endangered Species Act of 1973 is one of the dozens of United States environmental laws passed in the 1970s. Signed into law by President Richard Nixon on December 28, 1973, it was designed to protect critically imperiled species from extinction as a "consequence of economic growth and...

. The loggerhead sea turtle is only considered "threatened" under U.S. regulations.

Two species are IUCN Vulnerable: the desert tortoise (California and Nevada) and the gopher tortoise (Georgia, also the official tortoise of Florida). Three species are Near Threatened: the diamondback terrapin (Maryland), the ornate box turtle (Kansas), and the common box turtle (Missouri with the three-toed subspecies, North Carolina and Tennessee with the eastern subspecies). All the remaining state reptile species are Least Concern. Interestingly, all the non-turtle reptiles fall into this category, but the only two turtles in relative safety are the common snapping turtle (New York) and the painted turtle (Colorado, Illinois, Michigan, Vermont).

The tabulated IUCN ratings

 for the state reptiles all reflect species-level assessments; for most state reptiles, the IUCN does not discuss the subspecies situations. With the Arizona ridge-backed rattlesnake, the IUCN notes the subspecies has similar safety to the overall species, but does not formally rate the subspecies.

The ratings also do not reflect state-specific population conditions. For instance, for the Texas horned lizard, much of eastern Texas has lost the animal. Nevertheless, based on healthy populations in other parts of the West, especially New Mexico, the IUCN rates the animal Least Concern. For the timber rattlesnake (West Virginia), the IUCN notes the animal as losing range in many parts of the northeastern U.S., but because the animal is numerous in the southern Appalachians, it is also Least Concern.

The IUCN status of state reptiles at the genus level is ambiguous. For Massachusetts's garter snake

, the species found throughout much of North America and residing in Massachusetts. Within that genus, there are twenty-three species at Least Concern and two each at Vulnerable, Endangered and Data Deficient.
