A new study from Loma Linda University has officially debunked the long-held myth that baby rattlesnakes are more dangerous than adults. Researchers found that young rattlesnakes can control their venom just like adults, while adult snakes inject far more venom and cause more severe bites. The myth, traced back to 1967, has led to misinformed risk-taking, unnecessary fear, and even inappropriate medical care.
Think baby rattlesnakes are the scarier ones? Think again. A new study published in the journal Toxins by researchers at Loma Linda University has put one of the most persistent snake myths to rest: adult rattlesnakes are generally far more dangerous than their younger counterparts. Contrary to popular belief, baby rattlesnakes can control how much venom they release — they don't automatically dump it all in a single bite. Adults, however, carry and inject significantly larger volumes of venom, leading to more severe symptoms.
The researchers also traced how this myth took hold, finding it dates back to at least 1967 and was heavily amplified by California news outlets through the 1980s and 90s. Much of the misinformation stemmed from inaccurate quotes attributed to first responders and healthcare workers — not scientific experts. The good news: media coverage has grown more accurate since 2015.
By the Numbers
Why it matters: This misconception has real consequences — from people taking unnecessary risks around baby rattlesnakes to physicians over-treating bites under patient pressure. Regardless of the snake's age, any rattlesnake bite is a medical emergency requiring immediate care and antivenom.
