    12. San Francisco Garter Snake
    This colorful snake is a subspecies of the common garter snake. Native to San Mateo County and the extreme northern part of coastal Santa Cruz County in California, it has been declared an endangered species since 1967. And researchers estimate there are only about 1000 to 2000 members remaining. It is considered the most beautiful snake in the United States.

    11. Ocellate Mountain Viper
    Vipera wagneri, more commonly known as the ocellate mountain viper, is only found in parts of eastern Turkey. German naturalist Moritz Wagner first described the species in 1846, and it wasn’t seen again for 140 years. By the time scientists tracked a living specimen down in 1986, many believed it was extinct.

    10. Alcatrazes Lancehead
    Bothrops alcatraz, or the Alcatrazes lancehead, is a critically endangered, highly venomous pit viper species that only lives on the Alcatrazes Islands, about an hour’s boat ride (22.7 mi/35 km) off the coast of northern São Paulo in Brazil.

    9. Santa Catalina Island Rattlesnake
    Crotalus catalinensis, better known as the Santa Catalina Island rattlesnake, is only found on Isla Santa Catalina in the Gulf of California, east of the southern Baja California Peninsula. It’s a slender, medium-sized, venomous pit viper that grows to a little over two feet (0.6 meters) long and uniquely lacks a functioning rattle.

    8. Antiguan Racer
    Alsophis antiguae, or the Antiguan Racer, is only found on a handful of islands off the coast of Antigua and Barbuda, a twin-island country in the eastern Caribbean. Contrary to its deceptive name, the Antiguan Racer is a slow-moving ambush predator who preys on lizards and is harmless to humans.

    7. Darevsky’s Viper
    Vipera darevskii, or Darevsky’s viper, is a small, venomous snake endemic to northwestern Armenia, northeastern Turkey, and possibly Georgia. It’s named after Russian zoologist and herpetologist Ilya Darevsky, who was among the first researchers to find and describe the species.

    6. Round Island Boa
    Casarea dussemieri, or the Round Island keel-scaled boa, is a non-venomous snake species endemic to the uninhabited islet of Round Island, Mauritius, an island nation located in the Indian Ocean. It gets its common name from the small, keeled scales covering its body.

    5. Orlov’s Viper
    Vipera orlovi, or the Orlov’s viper, is a medium-sized, venomous viper native to Russia’s Black Sea coastal region and endemic to the Caucasus region. It wasn’t until 2001 that the species was distinguished from its close relative, the Caucasian viper.

    4. Aruba Island Rattlesnake
    Crotalus unicolor, otherwise known as the Aruba Island rattlesnake, is a moderately-sized, venomous pit viper species exclusive to the Caribbean island of Aruba, which is located about 18 miles (29 km) north of the Venezuelan coast.

    3. Cropan’s Boa
    Corallus cropanii, also known as Cropan’s boa, is a non-venomous, elusive tree boa endemic to the 116-square-mile (300 km2) Atlantic Forest of São Paulo, Brazil. It’s one of the world’s rarest boas.

    2. Short-Nosed Sea Snake
    The short-nosed sea snake, also known as the Sahul reef snake, occupies an estimated combined area of 3.86 square miles (10 km2) in the Ashmore and Hibernia Reefs off the northwestern Australian coast. It’s slender with a short head and pointed snout and grows up to 23.6 inches (60 cm) long, and typically dwells in waters exceeding 33 feet (10 meters) in depth.

    1. St. Lucia Racer
    While researchers are still learning about Liophis ornatus, or the St. Lucia Racer (also called the ornate ground snake), they know that it’s non-venomous, diurnal (which means it is active during the day), that it eats lizards, and that it grows up to 48.6 inches (123.5 cm) long.
