Description Of A Corn Snake 介绍玉米蛇
Corn snakes are slender with a length of 24 - 72 inches (61 to 182 cm) 6 feet... They are usually orange or brownish-yellow, with large, black-edged red blotches down the middle of the back. On the belly are alternating rows of black and white marks, resembling a checkerboard pattern. Considerable variation occurs in the coloration and patterns of individual snakes, depending on the age of the snake and the region of the country in which it is found. Hatchlings lack much of the bright coloration found on adults. Corn snakes are primarily diurnal. They readily climb trees and enter abandoned buildings in search of prey. However, they are very secretive and spend most of their time underground prowling through rodent burrows. They also often hide under loose bark and beneath logs, rocks, and other debris during the day.

Distribution and habitat 分布与栖息地
Corn snakes are found in the eastern United States from southern New Jersey south through Florida, west into Louisiana and parts of Kentucky. However, corn snakes are most abundant in Florida and the south-eastern U.S. Corn snakes may be found in wooded groves, rocky hillsides, meadowlands, woodlots, barns, and abandoned buildings.
Diet in the wild 野外的食物
Corn snakes do not usually feed every day instead they feed every few days. Young hatchlings tend to feed on lizards and tree frogs, while adults feed on larger prey, such as mice, rats, birds, and bats. They are constrictors. First a corn snake bites the prey in order to obtain a firm grip, then it quickly wraps one or more coils of its body around the victim. The snake squeezes tightly until it suffocates the prey. Then it swallows the food whole, usually head first. However, corn snakes have also been observed swallowing small prey alive.
玉米蛇不应该每天都喂食,每次喂食之间相隔一些日子反而更好。 幼体玉米蛇倾向于捕食小鱼和蜥蜴,成体则需要个体更大的猎物,例如白鼠、家鼠、鸟类和蝙蝠。 他们的捕食过程属于绞杀型。首先玉米蛇利用口器牢固地咬住猎物,然后利用自身细长的身体迅速将猎物缠绕几圈,同时身体进行强而有利的收缩,直到猎物窒息而死。 然后通常从猎物的头部开始吞食猎物。对于个体较小的猎物玉米蛇会直接吞食而不需要绞杀。
Zoo diet 动物园里的食物
They are fed mice, rats, and chicks.
Life span 寿命
The life span of the snake is up to 23 years in captivity, but is generally much less in the wild.
Corn snakes are not an endangered species. However, they are listed by the state of Florida as a Species of Special Concern because they face habitat loss and destruction in the lower Florida Keys. Corn snakes are often mistaken for copperheads and killed. They are also popular as pets. They are the most frequently bred snake species for pet purposes. However they are sometimes captured in the wild to be sold as pets. This does not seem to pose a serious threat to this species at this time.
