# Venomous Species and Bite Response

Part of the Reptile and Amphibian Study Merit Badge Digital Resource Guide: [Introduction & Overview](https://merit-badge.university/merit-badges/reptile-and-amphibian-study/guide/index.md)

*7. Safety with Venomous Species*

> **7.** Describe in detail six venomous snakes and the one venomous lizard found in the United States. Describe their habits and geographic range. Tell what you should do in case of a bite by a venomous species.

This requirement is about recognition and response, not fear. The safest Scout is the one who can identify the main venomous species in the United States, respect their space, and react correctly in an emergency.

## The Main Venomous Reptiles in the United States

Most lists for this requirement include these six venomous snake groups or species plus the one venomous lizard:

1. **Copperhead**
2. **Cottonmouth**
3. **Timber rattlesnake**
4. **Eastern diamondback rattlesnake**
5. **Western diamondback rattlesnake**
6. **Coral snake**
7. **Gila monster**

Your counselor may accept closely related regional species in place of one rattlesnake if that makes more sense for your part of the country.

## Habits and Range

### Pit vipers

Copperheads, cottonmouths, and rattlesnakes are pit vipers. They have heat-sensing pits between the eye and nostril, thick bodies, and hinged fangs. Many rely on camouflage and prefer to avoid conflict if left alone.

- **Copperheads** are common in wooded and rocky habitats in much of the eastern and central United States.
- **Cottonmouths** are associated with wetlands, swamps, slow water, and the Southeast.
- **Rattlesnakes** occupy a wide range of habitats, from forests to deserts, depending on the species.

### Coral snakes

Coral snakes are slender, brightly banded, and belong to a different venomous group from pit vipers. In the United States they are found mainly in the Southeast and parts of the Southwest, depending on the species.

### Gila monster

The Gila monster is the only widely recognized venomous lizard native to the United States. It lives in the Southwest, especially desert and scrub habitats, and is usually slow-moving and secretive.

## What to Notice Without Getting Close

A Scout should never try to prove bravery around a venomous animal. Instead, look for safe, visible clues:

- body shape and thickness
- head shape, if clearly seen
- color pattern or bands
- rattle, if present
- habitat and region
- behavior such as coiling, freezing, or warning display

> **Safety First!**
>
> Never try to handle, pin, poke, or photograph a venomous reptile at close range. Stay well back, warn others, and give the animal room to escape. Most bites happen when people try to touch or move the animal.

## What To Do If Someone Is Bitten

The correct response is simple and serious:

> **Be Prepared! Venomous Bite Response**
>
> - **Get help immediately**: call 911 or emergency services as soon as possible.
> - **Move away from the animal**: do not try to catch or kill it.
> - **Keep the person calm and as still as possible**: movement can speed venom spread.
> - **Remove rings, watches, or tight items** before swelling starts.
> - **Keep the bitten area still** and, if practical, at a comfortable level.
> - **Follow medical instructions quickly** and get professional care.

## What Not To Do

Do **not** cut the wound, suck out venom, apply ice, use a tourniquet, or rely on old myths. Those actions waste time and can make the injury worse.

> **Tip**
>
> For counselor discussion, learn one safe identification clue and one habitat clue for each venomous species you choose. That is more useful than trying to memorize a giant list of tiny details.
