What are the 4 types of snake venom?
Proteolytic venom dismantles the molecular surroundings, including at the site of the bite. Hemotoxic venom acts on the cardiovascular system, including the heart and blood. Neurotoxic venom acts on the nervous system, including the brain. Cytotoxic venom has a localized action at the site of the bite.

What is the most common type of venomous snake?
Cobras

What is cytotoxic snake venom?
Cytotoxins. Snake venom consists mainly of proteins. It is these proteins which cause the toxic effects on the body. Cytotoxic venom works on a molecular level by destroying the cell membrane thus destroying the tissue cell by cell.

What type of snake has the fastest-acting venom?
The venom of the black mamba is a protein of low molecular weight and as a result is able to spread rapidly within the bitten tissue. The venom of this species is the most rapid-acting venom of any snake species and consists mainly of highly potent neurotoxins; it also contains cardiotoxins, fasciculins, and calciseptine.
