# Corn Snake (*Pantherophis guttatus*)

> The corn snake (Pantherophis guttatus) is a gentle, colourful North American rat snake and one of the most popular pet snakes in the world. Native to the fields, woodlands and farmland of the southeastern United States, it grows to around 1.4 m (up to about 1.8 m) and is a non-venomous constrictor that hunts rodents. Docile and easy to keep, corn snakes can live 15 to 20 years in captivity and are listed as Least Concern.

## Appearance and colour

The corn snake is named partly for the maize-like checkerboard pattern on its belly and partly for its habit of hunting around grain stores. Wild individuals are typically orange or reddish-brown with bold, black-edged red or orange blotches down the back. Decades of captive breeding have produced a huge range of colour and pattern variations, known as morphs, from snow-white to lavender. A slender adult reaches about 1.4 m long and weighs around 0.9 kg (2 lb).

## A non-venomous constrictor

The corn snake is completely harmless to people, with no venom and only tiny teeth. It kills its prey by constriction, coiling around a rodent and tightening its grip until the animal stops breathing before swallowing it whole. Corn snakes are carnivores that feed mainly on mice, rats and other small rodents, along with the occasional bird or egg. This appetite for rodents makes them welcome around farms and barns, where they help control pests.

## Habitat and behaviour

In the wild the corn snake ranges across the southeastern United States, favouring fields, woodlands, farmland and abandoned buildings. It slithers across the ground and is a capable climber, scaling trees and rafters in search of prey and shelter. Mostly active at dawn, dusk and night, it spends much of its time hidden under logs, rocks or debris. When alarmed it may vibrate its tail against dry leaves, mimicking a rattlesnake to bluff predators.

## Why it is a popular pet

The corn snake is often recommended as an ideal beginner's snake because it is calm, tolerant of handling and simple to care for. It stays a manageable size, feeds readily on frozen-thawed rodents, and rarely bites. Its wide array of colour morphs also makes it a favourite among keepers and breeders. With good care a pet corn snake can live 15 to 20 years.

## Reproduction and life cycle

Corn snakes breed in spring, after emerging from a cooler winter dormancy that helps trigger the cycle. The female lays a clutch of around a dozen eggs in a warm, humid, hidden spot such as rotting wood or leaf litter, then leaves them to develop on their own. The eggs hatch after about two months, and the young snakes are independent from birth. In the wild corn snakes generally live several years, but in captivity they commonly reach 15 to 20 years.

## Conservation status

The corn snake is listed as Least Concern and remains common across its native range in the southeastern United States. It is one of the most widely bred snakes in the world, so the pet trade draws overwhelmingly on captive-bred animals rather than wild ones. Habitat loss and road deaths affect some local populations, but the species as a whole is secure. Its adaptability to farmland and disturbed land has helped it persist alongside people.

## Frequently asked questions

### Are corn snakes venomous or dangerous?

No. Corn snakes are completely non-venomous and harmless to people. They kill prey by constriction, are very docile, and rarely bite, which is why they are considered one of the safest pet snakes.

### How big do corn snakes get?

Corn snakes typically grow to around 1.4 m long, with some reaching about 1.8 m (6 ft), and weigh roughly 0.9 kg (2 lb). They are a slender, moderately sized rat snake.

### What do corn snakes eat?

Corn snakes are carnivores that feed mainly on mice, rats and other small rodents, along with the occasional bird or egg. In captivity they are usually fed appropriately sized frozen-thawed rodents.

### How long do corn snakes live?

With good care a pet corn snake can live 15 to 20 years. Wild corn snakes generally live shorter lives because of predators and other hazards.

### Why are corn snakes good pets for beginners?

Corn snakes are calm, tolerant of handling and simple to care for. They stay a manageable size, feed readily on frozen-thawed rodents, rarely bite, and come in a wide range of attractive colour morphs.

### Why is it called a corn snake?

The name comes partly from the maize-like checkerboard pattern on the snake's belly and partly from its habit of hunting rodents around grain and corn stores. It is a type of North American rat snake.
