Coral Snakes Reproduction
Courtship and Mating
Snakes are usually solitary animals, are virtually deaf, have poor eyesight, and have no voice, so finding a mate is not always easy for them. As far as is known snakes rely on a scent secreted from the anal glands to find each other, and a male follows the scent trail of any female in reproductive condition. Most snakes do not have the elaborate courtship displays seen in other groups of vertebrates, such as birds and mammals.
Egg laying and birth
The length of time the egg develops in the mother, or gestation period, varies according to conditions, particularly temperature. The eggs are generally laid in shallow holes covered with a thin layer of soil. Some snakes lay their eggs under stones or in hollow logs or tree stumps. The main aim is to provide a site that is not to hot by day nor too cold at night. The female snake will not look after her eggs. Each egg contains all of the nutrients required for the full development of the young.
Males and Females
As far as is known, there are males and females of all species of snakes but one. The exception is the Brahminy Blind snake, widely distributed throughout the warmer parts of the world, only occurs as a female. With no males to mate with, females use pathogenesis and produce offspring from unfertilized eggs. All of the young are females.
The Snake Egg
The eggs of snakes, like those of all reptiles, and birds, have large amounts of yolk. The yolk contains the fats and carbohydrates necessary for development of the embryo. The embryo starts its development as a flat little disk lying on the surface of the yolk and, as it develops, it lifts away from the yolk and begins to form itself into a young snake. The yolk nourishes it throughout its development, and towards the final stages, is drawn into the snake through a slit in its underside, which is seen as a small scar when the snake hatches.
