These snakes' scales are different colours
The San Francisco Snake is known as the most beautiful serpent in North America as its scales variety in different colours. They, most commonly, have an orange head connected to three stripes that go down to the tail. The greenish-blue, red, white stripes are outlined with a strip of black making the colours stand out from a distance. Young snakes start from 12.5 to 23 cm and can grow from 46 to 137 cm. Males usually are smaller but have a longer tail than females.
The San Francisco Snake is located along the Bay of San Francisco in North Amercia. From a place called Peninsula across the San Mateo Country Border.
The snake prefers wetlands with high grass ponds near open hillsides. They also don't mind freshwater ponds as these are the perfect places for them to hunt. During the hibernation period, they tend to hide in warmer places like in burrows and under rocks.
THE HABITAT
The San Francisco Snake prefers thick high grass ponds near open hillsides. They tend to like wetlands or damp, grassy areas as they can hunt in waters but not over 2 inches deep. They also don't mind freshwater ponds. As long as the salt level in the water is low, they will enjoy the place. This is mainly because their favourite prey cannot survive in more salty water environments.
All reptiles hibernate, as do the San Francisco Snake. During the seasons, they will find a new habitat. The snake usually acts solitarily but in order to prevent heat loss, they hibernate in groups. Either in thick layers of grass or rodent burrows, under rocks or stumps.

After the hibernation period, the male snakes try to attract the females. The females then get to pick who they want to mate with and leaves the area to lay the eggs. The male finds another partner and redoes the process.
The snake uses his tongue to take the chemicals out from the air. He then places the chemicals in an organ in his mouth; this becomes a pheromone which can attract females. It's like a signal and can be used to track down a specific snake.
food
They eat small animals, from earthworms to amphibians to bugs like leeches
Although the San Francisco Snake is a carnivore, it is ranked near the bottom of the food chain.
FOOD LIST
1. Earthworms
2. Amphibians (the toxic from frogs has no effect on the snake)
3. bugs (leeches, slugs)
4. fishes
5. other snakes
6. weak birds

CAUSES OF EXTINCTION
- Illegal Killing of the speicies
- Urban Expansion
- Water Pollution
CAUSES OF EXTINCTION
Illegal Killing- It is a huge disadvantage to the animals when they are hibernating. These animals hibernate in groups. It is much easier for humans to find and kill a clutter of snakes sleeping than to hunt down each snake individually.
Urban Expansion- We are taking over all the natural habitats of this animal. Don't we have enough already?
Water Pollution- We are careless about the rubbish we produce. Rubbish either ends up on the ground around us or in the marine habitats. The rubbish is extremely dangerous to those animals.

WHAT CAN WE DO?
WHAT WE DO NOW IS THE FUTURE!
To the TECON Wildlife Fund,
I hear you're going to donate a certain amount of money to a certain Endangered Species. The San Francisco Garter Snake would be a fabulous choice as it is truly a beautiful gift God has given us. We already have plans to help the snake and hope to be able to use your funding to the best.
The snake is dying off because of the wrong-doings of humans. We do cause most animal's extinctions but right now, there are hunters out there, killing these snakes with their own hands. There is no way we can escape the fact that if this continues, we will eventually kill these animals all out.
If you donate us your money, we will make great use to it. We plan on building more facilities for the injured snakes to temporarily live in. We have also started organisations made just to protect the snake's habitats from any harm. These organisations are trying to keep the reproduction at a healthy level.
It is our responsibility to take care of these animals. I believe NOW is the future. What we do NOW will effect the future, so we're starting NOW to make a change for these animals. Thank you for your consideration and time. I do hope that you will acknowledge this beautiful species.
Yours sincerely,
SERELL Wildlife Organisation
