Quick Answer
Snake size affects the severity of the bite, but not directly. Larger snakes may have more venom but also deliver it in larger quantities, potentially making the bite more severe. However, many factors influence the severity of a snakebite, including the species, the amount of venom injected, and the individual's reaction to it.
Understanding Venom Delivery
The amount of venom delivered by a snakebite is not directly related to its size. For example, the inland taipan, a relatively small species, is considered the world’s most venomous snake due to its potent venom. On the other hand, larger species like the Burmese python may have more venom, but they often inject much less when biting. In general, a snake’s fangs determine the amount of venom delivered, not its size.
Measuring Venom Quantity
When treating a snakebite, medical professionals often measure the amount of venom delivered using a venom extractor or by injecting antivenom. The amount of venom is usually expressed in units, such as milligrams or miligrams per liter. For example, the venom of the eastern brown snake is highly toxic, with a potency of 52.6 mg per liter. In contrast, the venom of the king cobra is less potent, with a potency of 13.3 mg per liter.
Species-Specific Treatment
Different species of snakes require different treatments due to variations in venom composition. For instance, antivenom for a western diamondback rattlesnake is not effective against a cottonmouth bite. Medical professionals often rely on species identification to determine the correct treatment. In some cases, they may use a combination of antivenom and other medications to counteract the effects of the venom.
