Ring-necked Snake

Diadophis punctatus

No medically significant venom known

Small, secretive colubrid with a distinctive yellow or orange neck band and smooth-scaled gray to black body; mildly rear-fanged with no medically significant venom to humans. Typically nocturnal or crepuscular, feeds on amphibians, small reptiles, and invertebrates, and is often found under logs, rocks, or leaf litter. Not dangerous to people but should not be handled; beneficial for controlling pest amphibians and invertebrates.

Rock Rattlesnake

Crotalus lepidus

Venomous

Crotalus lepidus is a small- to medium-sized pitviper commonly called the rock rattlesnake. It inhabits rocky, mountainous and canyon areas in the southwestern United States and northern/central Mexico. It is venomous and can deliver medically significant bites; exercise caution and keep distance.

Rough Earthsnake

Virginia striatula

No medically significant venom known

Rough Earthsnake (Virginia striatula) is a small, secretive, non-aggressive colubrid native to the southeastern United States and adjacent parts of Mexico. It spends much of its time under ground cover and in loose soil, feeding mainly on earthworms and soft-bodied invertebrates. Bites to humans are extremely rare and not medically significant.

Myths & common misconceptions

Myth

Baby snake venom control

Baby venomous snakes are more dangerous because they cannot control how much venom they inject.

Juvenile venomous snakes can deliver medically significant bites, but the common claim that they are automatically more dangerous because they cannot control venom delivery is not supported as a general rule. Adult snakes usually have larger venom glands and can deliver a larger total amount.

Bottom line: Treat every suspected venomous snakebite as a medical emergency, regardless of the snake’s age.

Myth

Triangular head

A triangular head always proves that a snake is venomous.

Head shape alone is unreliable. Many nonvenomous snakes flatten or widen the head defensively, and viewing angle can change the apparent shape.

Bottom line: Do not approach a snake to inspect its head. Use multiple traits, location, and a safe-distance photograph.

Myth

Snakebite tourniquet

A tourniquet is a good first-aid treatment for a snakebite.

Tourniquets can worsen tissue injury and are not recommended for typical United States snakebites. Emergency evaluation is more important.

Bottom line: Call 911 or Poison Control at 1-800-222-1222. Keep the person calm and do not cut, suck, ice, or tourniquet the bite.

Myth

Yellow-green copperhead tail

A yellow-green tail tip on a juvenile copperhead is a developing rattle.

Young copperheads can have a contrasting yellow or greenish tail tip used in caudal luring. It is soft and tapered, not a segmented rattle. The bright color usually fades with age.

Bottom line: Never move closer to inspect the tail. The feature is a clue, not permission to approach or handle the snake.

Myth

Tail vibration

Any snake vibrating its tail is a rattlesnake.

Several non-rattlesnake species vibrate their tails when threatened. Dry leaves can make the sound resemble a rattle.

Bottom line: A defensive tail vibration does not identify the species. Keep your distance.
