Snake venom's danger is not solely based on size. Young snakes possess potent venom that quickly immobilizes prey. Adult snakes produce more complex venom affecting various body functions. While juvenile venom can be strong, the total amount injec...
A little snake that rests on the leaf litter may cause no alarm, but its bigger counterpart moving on a path will trigger fear and caution in any person. Size seems to be a quick way of assessing the risk involved. However, scientific studies have proven that the degree of peril does not necessarily correlate with scale. Investigations conducted into the composition of venom indicate that even baby snakes possess venom that is tailor-made for their specific age group.
According to studies published by PubMed Central, young Bothrops jararacussu generate venom with high pro-coagulant properties that help them paralyze their prey swiftly (PMC). The swift effect of the poison makes up for their lack of physical strength and enables them to become efficient hunters. Instead of depending on their size and muscle strength, the little snakes make use of their chemistry skills.
Juvenile Venom Works Differently
The difference between juvenile and adult venom has to do with the nature of the task rather than the potency of the substance. According to research, the main action of juvenile venom occurs very quickly after the blood comes into contact with the poison; accelerated clotting and hemorrhaging result in rapid immobilization of the prey (PMC). That is to be expected from a smaller predator that does not have the luxury of prolonged fighting. In contrast, the venom developed by adult snakes is much more complicated as it affects multiple bodily functions. Nevertheless, it has been shown that the lethality rates of juvenile and adult venoms can be similar despite the fact that their biochemistry works differently (PMC). The importance of that point lies in the understanding that venom lethality is a complex issue that cannot be simplified. There are many factors involved, and danger does not depend on a single one.

What Does This Mean for Human Risk?
With regards to human interaction, however, the issue becomes somewhat complicated. As shown by clinical studies into rattlesnake bites in ScienceDirect, large snakes will be responsible for symptoms that are usually severe because of the increased amounts of venom produced by these creatures (ScienceDirect). From this point of view, one can conclude that although younger venom could be stronger, the overall amount of toxin that enters the body determines the level of severity of symptoms. As such, a smaller creature may produce a lesser amount of venom, but its effect may still be severe. Consequently, it would be incorrect to consider either a larger or a smaller snake as the most dangerous, since each snake creates a certain form of threat.
