One of the most persistent myths in American snake safety is officially wrong, and researchers are concerned that its persistence has caused real harm, both to people treated too aggressively after juvenile rattlesnake bites and to juvenile rattlesnakes killed by hikers acting on misinformation.
A study from Loma Linda University, published in the journal Toxins and highlighted by ScienceDaily on July 7, 2026, formally debunks the widespread belief that baby or juvenile rattlesnakes are more dangerous than adults because they cannot control how much venom they inject. The research confirms the opposite: juvenile rattlesnakes can regulate their venom delivery just as precisely as adults, while adult rattlesnakes possess significantly larger venom glands and inject substantially more venom per bite — causing more severe symptoms and requiring more intensive medical treatment.
