Depending on the species of snake, there are 5 types of venom that have been identified. Each venom acts differently inside the body of the victim:
- Neurotoxic venom - Cobras and Mambas - attacks the central nervous system, and starts to affect movement, breathing, swallowing, speech and sight.
- Haematoxic venom - Boomslang - affects the blood by using up the clotting factors so it no longer coagulates leading to extensive blood loss into the tissues.
- Cytotoxic venom - Puff Adders - attacks the body cells or tissues, this bite is extremely painful, with much swelling and marked symptoms of shock.
- Myotoxic venom - sea snakes - attacks the muscles and can lead to death from kidney and heart failure.
