The reproduction habit of the Fremont snakes will be in various forms depending on the location and the species of the snakes. Snakes that live in the cooler location will mate during the early part of the summer and late spring season. Those that are found in the tropical area can mate all throughout the year. Accessibility of food and the temperature plays a crucial role in the mating process of the snakes.

The Snake's Mating Process

Once the Fremont female snake is prepared to mate, they will start releasing pheromones that will attract the male species. While she is doing her daily grind, she will be leaving this scent on various locations. Once the mature male snakes capture this scent, he will be following the trails of the scent until he finds the female snake. 

The Courting Process

The male snake will court the female snake by bumping its chin on the head of the California female adult snake. He will then crawl on top of her. Once she raised her tail, this will be an indication that the female snake is willing to copulate. He will then wrap his tail around the lower part of the female that will enable them to meet their cloaca. This is part of the snake where all the body wastes and fluids will be released. The male snake will then insert the hemipenes where the sperm of the snakes will be delivered. The mating process may last for hours but on some instances this will go on for an entire day.

The Reproduction Habit

The female snake will reproduce 1-2 times per year. The method of giving birth will differ from different California species. There are some snakes that will deliver a live young and there are those that will lay eggs. There are also others that will hatch the eggs internally and will deliver the babies alive. Compared to birds that need to sit on their eggs to incubate, most snakes will simply leave the eggs after laying them. There are also those that will protect their eggs.

After laying her eggs, there may be remaining sperms in her body that she can utilize again. If not, she will once again look for possible mate. The snake in the eggs will have sharp fangs that they can use to come out of the shell. Those that are venomous will be equipped with the lethal dose of venom to help them survive. 

Since the Fremont mother snakes have already left them, the young snakes have to fend for themselves. While they are still young, they will be highly vulnerable against different predators in the wild such as lizards, fox, and birds. When in the wild, the young snakes have an increased mortality rate. Their appearance will be highly similar with their parents except of course their size. Reproduction of species is important to make sure that the lineage of the snake will survive. This is why this process has been deemed necessary to all types of living beings.
