A snake is a long limbless reptile that has no eyelids, a short tail, and jaws that are capable of considerable extension. Some snakes have a venomous bite.
Snakes have a very highly developed sense of sight, taste, hearing and feeling. They use their senses to find their prey. Some snakes kill their prey by injecting venom into the animal by bite or they can use their strength and wrap around their prey, squeezing the animal to death.
Snakes can move on sand and rocks. They can also fit through really really thin cracks and crevasses in rocks without harming themselves.
What is venom? Venom is the toxin used by venomous animals. Venom is injected into prey by a bite or a sting. 600 out of the 3,000 snake species are venomous. Every type of snake with venom, has there own specific venom. There are two types of venom, neurotoxin and hemotoxin. Neurotoxic venom shuts down the nervous system making your muscle stop working. Neurotoxic venom also stop your lungs from pumping which leads to suffocation.
Hemotoxic venom shuts down your circulatory system causing clotting compounds from working correctly. If your clotting compounds stop working, you will bleed out uncontrollably.
However, snake venom also has many healing powers. Southern copperhead snakes carry protein in their venom called contortrostatin. Contortrostatin has been tested on mice that have breast cancer. After the testing for two weeks the venom protein reversed the growth of the tumor, so the tumor gets smaller and eventually goes away. The protein also slowed angiogenesis
(the growth of blood vessels that allow the cancer to spread faster).
Snakes help halt the spread of lyme disease, as well. There are three species of bacteria that carry lyme disease, that tend to live in rodents. Diseased ticks infect rodents when they bite
them; then the rodent gets the disease. If a tick that is diseased bites a human, it would disease the person. Rattlesnakes
