Blindsnake Dinner Etiquette: Decapitate First, Then Swallow

I have been living in Hawaii for six years now, and I have once, and only once, caught a glimpse of the snakes that call these islands home.

Yes, you read that right: there are snakes in Hawaii. Technically, there are two species that can be found here, but the yellow-bellied sea snake is so rare it almost doesn’t count. The other — the brahminy blindsnake — is actually quite common, though it’s easy to understand why it’s often overlooked: these small, black creatures only grow to be about six inches long and dwell in the dirt. They are often mistaken for worms because of their diminutive size and underground lifestyle. The same species can be found worldwide: natively throughout Asia and Africa and non-natively in several places, including Hawaii. They’re also the only species of snake that is entirely parthenogenic — no male has ever been collected. They simply don’t look or act like we think a snake should. And now, scientists have documented yet another trait that makes them stand out from their serpentine brethren: before swallowing, they will sometimes decapitate their meal.

Baby Snake Shows Why The Dead Can Still Be Deadly

Remember that story from last fall about the Chinese chef that died after being envenomated by the severed head of a cobra he was cooking? (Well, if not, here’s a good summary.) Many dismissed the tale outright, thinking a snake couldn’t possibly be lethal if it was no longer living. But a great photo taken this week by Lee Reeve shows just how dangerous venomous animals can be, even after death:

Lee found this wee western diamondback rattlesnake (Crotalus atrox) dead this morning. It was the runt of a recent litter, and had struggled in spite of months of assisted feeding, so Lee wasn’t surprised the little guy didn’t make it. But just because the small snake was dead didn’t mean Lee could be carefree about handling it, as he explained in a Facebook post:

“Looked like he hadn’t been dead for very long, so I took the opportunity to show why they’re dangerous, even when dead. The liquid coming from the fangs is venom, and will be just as toxic as it was when the snake was alive. Prick your finger on and the fang (or even the bottom teeth), and you got yourself an envenomation.”

Even once dead, venom that is stored in the venom gland can be injected into an unsuspecting victim if pressure is applied. And snakes, like other animals (even us!), can exhibit muscle movements post-mortem, so even if the animal isn’t alive, you can’t be sure it won’t move unpredictably. As someone who has worked for years with venomous animals, I’ve had to be careful with my study organisms even months after their demise (frozen venom can stay potent for a long time!).

So should you come across a dead snake — or anything else with venomous fangs, spines, spurs, etc — be careful! Don’t assume the dead are harmless to the living.

 

Is the next blockbuster drug hiding in a century-old venom?

Prialt, a revolutionary painkiller 1,000 times as strong as opiates without the addictive side effects.
Prialt, a revolutionary painkiller 1,000 times as strong as opiates without the addictive side effects.

Aggrastat. Byetta. Captopril. Integrilin. Prialt. What do these drugs have in common? Not what they’re used for, certainly. From angina to diabetes, they treat different diseases or conditions, and all have very different markets. They’re sold by different companies and were discovered in different laboratories around the world. But all have one simple thing in common: they come from animal venoms.

Did Allergies Evolve To Save Your Life?

As most of my friends on the mainland don longer sleeves and more layers, it’s hard not to be a little smug about living in paradise. While, in their neighborhoods, leaves are falling off of trees and icy winds threaten to bring snow, I can throw on a T-shirt and shorts, grab a picnic basket, and hike to a scenic overlook for lunch. But Hawaii’s ever-sunny weather comes with one side-effect that can be deadly serious: year-round, Hawaii has bees.
