Everything You Need To Know About Corn Snakes – The corn snake (Pantherophis guttatus), sometimes called the red rat snake, is a species of North American rat snake in the family Colubridae. The species subdues its small prey by coercion.

It is found throughout the southeastern and central United States. Although it superficially resembles the copperhead viper (Agkistrodon contortrix) and is often killed as a result of this mistaken identity, the corn snake lacks a functional vomer and is harmless. The corn snake is useful for humans

The corn snake is named for the species’ regular presence near grain stores, where they prey on mice and rats that eat harvested corn (maize).

The Oxford English Dictionary cites this usage as early as 1675, while other sources claim that the corn snake is so named because the distinctive, nearly checkered pattern of scales on the snake’s abdomen resembles the variegated corn kernels.

In the wild, it usually lives about t to fifteen years, but in captivity it can live up to 23 years or more.

The natural corn snake is usually orange or brown in body with large red spots outlined in black down their back.

This black and white check pattern is similar to Indian corn, from which the name corn snake may have come.

Astounding Facts About Corn Snake

The corn snake can be distinguished from a copperhead by the corn snake’s brighter colors, leaner build, thin head, round pupils, and lack of heat-singing pits.

Until 2002, the corn snake was considered to have two subspecies: the nominate subspecies (P. g. guttatus) described here, and the Great Plains rat snake (P. g. emoryi). The latter has since been separated as its own species (P. emoryi), but is still occasionally treated as a subspecies of corn snake by hobbyists.

P. guttatus has been suggested to be divided into three species: the corn snake (P. guttatus), the Great Plains rat snake (P. emoryi, corresponding to the subspecies P. g. emoryi), and the Slowinski corn snake (P .slowinskii, occurring in western Louisiana and adjacent Texas).

P. guttatus was previously placed in Elaphe gus, but Elaphe was found to be paraphyletic by Utiger et al., leading to the placement of this species in Pantherophis gus.

What Should I Consider Before Buying A Corn Snake?

The placement of P. guttatus and several related species in Pantherophis rather than Elaphe has been confirmed by further phylogenetic studies.

Molecular data have shown that the corn snake is actually more closely related to kingsnakes (Gus Lampropeltis) than to the Old World rat snakes (Gus Elaphe) with which it was previously classified. The corn snake has been bred in captivity with the California kingsnake (Lampropeltis californiae) to produce fertile hybrids known as “jungle corn snakes.”

In the wild, the corn snake prefers habitats such as overgrown fields, forests, trees, palmetto flatwoods, and abandoned or rarely used buildings and farms, from sea level to 6,000 ft (1,800 m). Typically, the corn snake stays on the ground until it is four months old, but it can climb trees, rocks, and other elevated surfaces.

In colder regions, the corn snake broods during the winter. However, in milder climates along the coast, it shelters in rock crevices and logs during cold weather. It can also find shelter in small, enclosed spaces, such as under a house, and come out on warm days to soak up the sun’s heat. During cold weather, the corn snake is less active, so it hunts less.

Often called the “American corn snake”, P. guttatus is a prohibited pest in much of Australia. There are active eradication campaigns and public advisories in Victoria,

Corn snakes (along with other colubrids) have been found to reach sexual maturity by size rather than age.

Corn snakes are relatively easy to breed. Although not necessary, they are usually put through a chilling period (also known as scratching) that takes 60-90 days to prepare them for breeding. Corn snakes thrive around 10 to 16 °C (50 to 61 °F) in an undisturbed location with little sunlight.

Corn snakes usually breed soon after the winter chill. The male courtes the female mainly with tactile and chemical signals, returns one of his hemipods, inserts it into the female and ejaculates his sperm. If the female is ovulating, the eggs will be fertilized and she will begin to sequester nutrients in the eggs, secreting a shell.

Corn Snake Handling & Body Language Tips

Egg-laying occurs a little over a month after mating, with 12-24 eggs deposited in a warm, moist, hidden location. Once laid, the adult snake abandons the eggs and does not return to them. The eggs are elongated with a leathery, flexible shell. About 10 weeks after laying, the young snakes use a specialized scale called an egg tooth to cut slits in the egg shell, from which they emerge about 13 cm long.

Breeding in captivity must be done correctly so that the mortality rate of the herd is reduced. This includes correct sexing, establishing the right pre-breeding conditions and timely mating of adults. Corn snakes are temperate colubrids and share a reproductive pattern where females increase their feeding during the summer and fall. This only applies to corn snakes that are sexually mature, which usually indicates that the snake is about 75 cm (30 in) in length or 250 g in weight.

Like all snakes, corn snakes are carnivores and, in the wild, eat every few days. While most corn snakes eat small rodents, such as the white-footed mouse, they may also eat other reptiles, or amphibians, or climb trees to find unprotected bird eggs.

The seasons play a large role in the thermal regulation patterns of corn snakes, which is the primary digestive mechanism for snakes. During the fall, corn snakes maintain a body temperature approximately 3 degrees Celsius higher than the ambient temperature after consuming a meal.

While corn snakes in winter are not able to thermoregulate after digestion. Captive snakes do this using heat mats, as a heat source underneath replicates their natural conditions. Corn snakes demonstrate nocturnal patterns and use warm soil at night to thermoregulate, so heat mats replicate this source.

American “rat snakes,” such as P. guttatus, had voluminous ancestors that lost their volume as they evolved constriction as a means of capturing prey.

Behavioral/chemical studies with corn snakes suggest that odor cues are of primary importance for prey detection, while visual cues are of secondary importance.

However; a study conducted by Dr. David Holzman of the University of Rochester found in 1999 that the cognitive abilities of snakes (specifically related to spatial learning) actually rival those of birds and bats.

Holzman challenged the typical testing method being used by biologists to examine the swimming abilities of snakes, claiming that the structure of the ara itself biologically favored the rods. He hypothesized that if the typical arena used to test animals was modified to meet the snake’s biologically innate goals by providing them with problem sets that they would likely oppose in their natural state, it would provide a more accurate of their intelligence. .

The study involved testing 24 captive-bred corn snakes, placing them in a wide tub with walls too high to climb out. Eight holes were cut down, with one hole leading to a shelter. An intse light was positioned to shine directly on the fields, exploiting the snake’s natural aversion to bright optical spaces. This provided a biologically significant objective for snakes: to seek a cozy dark shelter.

Not only did they find that snakes display a keen ability to learn and navigate their surroundings, given the right intelligence, but they also found that snakes rely on their vision much more than many had previously assumed. herpetologists. However, they found that the younger snakes were able to find the holes more quickly than the older snakes, as the younger snakes were more adept in their application of the sses – where the older snakes relied more on their eyesight .

Corn snakes are one of the most popular snake species to keep in captivity or as pets, second only to the ball python. They are the most popular snakes in Brazil.

Pet Corn Snake: Personality, Diet & Care

Their size, calm temperament and ease of care contribute to this popularity. Captive corn snakes tolerate being handled by their owners, even for long periods.

After many periods of selective breeding, captive-bred corn snakes come in a wide variety of different colors and patterns. These result from the recombination of dominant and recessive genes that code for proteins involved in chromatophore development, maintenance, or function. New variations, or morphs, become available each year as breeders gain a better understanding of the genetics involved.

There are thousands of possible composite morphs. Some of the more popular ones are listed here.

Hypo Corn Snake

Hybrids between corn snakes and any other snake are very common in captivity, but rarely occur in the wild. Hybrids within the gera Pantherophis, Lampropeltis or Pituophis have so far proven to be fully fertile.

When corn snake hybrids are found in the wild, they are usually hybridized with other Pantherophis species, which
