King Snake vs Coral Snake
Verdict: Snout and band order: a coral snake has a black snout and red bands that touch yellow bands. A scarlet kingsnake has a mostly red snout and red bands that touch black. Never rely on the rhyme alone, and never handle either snake.
Kingsnakes are harmless, nonvenomous constrictors, and some, like the scarlet kingsnake, have red, black and yellow bands that copy the venomous coral snake. The eastern coral snake is the dangerous one. The best field marks are a black snout followed by a broad yellow band on the coral snake and red bands that touch yellow.
The old rhyme says red touches black is safe and red touches yellow is dangerous. It works for the three native US coral snakes but fails for coral snakes in Mexico and farther south, and some harmless shovel-nosed snakes break it. Many kingsnakes, such as the common kingsnake, look nothing like a coral snake, since they have whitish-yellow bars on black.
King Snake vs Coral Snake side by side
| Trait | King Snake | Coral Snake |
|---|---|---|
| Venom | None; a nonvenomous constrictor | Venomous with neurotoxic venom |
| Snout | Scarlet kingsnake's snout is nearly always red | Black, followed by a broad yellow band |
| Band order | Red touches black; red and yellow stay apart | Red touches yellow |
| Pattern, common kingsnake | Chain-like whitish-yellow bars on a black back | Red, yellow and black rings encircling a slender body |
| How it handles prey | Constricts rodents, eggs, amphibians and reptiles | Uses venom |
| Role as look-alike | Eats snakes, including venomous ones, and is immune to venom of snakes in its area; the scarlet kingsnake is the harmless mimic | The eastern, Texas and Arizona coral snakes are the venomous US species |
| Temperament toward people | Harmless, but may bite if grabbed | Not aggressive; would need to be handled to bite |
| Recorded bites in North Carolina | Nonvenomous, so no venom bites | No coral snake bites on record in the state's history |
| Rhyme reliability | Rhyme applies only to US species; shovel-nosed snakes can break it | Works for the three US coral snakes |

When you are looking at which
King Snake
- The snout is red and the red bands touch black bands, with yellow kept apart.
- The snake is black with chain-like whitish-yellow bars and no red at all.
- It is a large, thick snake that constricts a rodent or eats another snake.
- You are looking at a photo and the red band is bordered by black on both sides.
Coral Snake
- The snout is black and is followed by a broad yellow band.
- Red bands touch yellow bands and the snake has complete red, yellow and black rings.
- The body is slender and cylindrical with the rings encircling it.
- You are in the Southeast, Texas or Arizona range of coral snakes and the colors fit the red-on-yellow pattern.
How this works
The quiz uses four visual cues: snout color, which color touches the red bands, the overall pattern, and what lies behind the snout. It stops at four because a fifth cue would need handling the snake. They follow state wildlife agency guidance for separating coral snakes from scarlet kingsnakes and scarlet snakes.
It only covers the eastern United States. Texas and Arizona coral snakes, shovel-nosed snakes and tropical coral snakes can break the patterns, and a photo may hide the snout. When unsure, treat it as venomous and keep your distance.

Frequently asked questions
How can I tell a king snake from a coral snake?
Check the snout and band order. A coral snake has a black snout followed by a broad yellow band, and its red bands touch yellow. A scarlet kingsnake has a mostly red snout and red bands touching black.
Does the rhyme red touches yellow kill a fellow work?
It works for the three US coral snakes but fails for coral snakes in Mexico, Central America and South America, and some harmless shovel-nosed snakes break it. Experts say to use several features and never to handle the snake.
Are coral snakes aggressive?
No. They are described as not aggressive, and North Carolina has no human bite recorded in its history. Almost all bites come from people picking up or stepping on the snake.
Do kingsnakes really eat venomous snakes?
Yes. Kingsnakes are immune to the venom of snakes in their area and eat other snakes, which is a reason to leave them alone.
