Snakes Eat Their Own Hearts

Can you imagine being hungry enough to eat your own heart and able to survive after?

Researchers have been examining snakes for clues of ways to improve the survival rates of humans and animals during long periods without food. Jennifer Viegas reports in the Discovery News dated Aug. 20, 2007 that certain snakes have been known to survive for two years without food. Their survival has not been without cost, however.

A researcher and author, Marshall McCue conducted a study which was published in Zoology, examining the physiology of snake starvation. He studied 64 snakes, weighing and measuring them before and after the 168 day study noting remarkable weight loss and energy levels. McCue stated that snakes expended an average of 80% less energy during the experiment only making a move when they thought there was food available, and lost an average of 24.4% of their body mass.

What was remarkable was that they grew longer, and their bone structure in their heads had grown allowing for a wider range of prey to be swallowed. Another remarkable discovery was that the snakes digested part of their own heart muscle, which they would be able to rebuild after a nutritious meal.

Snakes Do Not Normally Stalk their Prey

Aaron Rundus, a researcher from the University of Nebraska, who also studies snakes states that snakes are able to survive under the worst of conditions. One reason for this according to Rundus is that snakes do not stalk their victims but wait for them to “cross their paths.” Except maybe in this story found released by the Associated Press:

Family Dog Killed By Python

The press release dated February 27, 2008 reported a news item about a 16-foot python who had stalked a family dog for days before swallowing it whole in front of two terrified children. These young children, aged 5 and 7 lived near Kuranda in Queensland State when their beloved terrier-Chihuahua was last seen alive. The family had seen the snake in the dog’s bed a few days prior, a sign that the snake may have been waiting for his window of opportunity.

Wildlife S.O.S. Gives Us Many Interesting Facts About Snakes

Although generally snakes do not show any paternal interests, the King Cobra is an exception to the rule. Mother snakes will actually construct a nest for her young, but make it a point to leave the nest just prior to her offspring (20-50 eggs) hatching. It is believed the reason for her leaving at that point is to prevent from eating her own young. The male king cobra has patrolled the area until this point, keeping unwanted visitors away.

The King Cobra is unique in another way. It eats almost only snakes, with the rat snake being its favorite meal.

Because hatched young snakes do not have any parents to look after them, they hatch on their own breaking out of their eggs using their fine little teeth. The cobra is born with the ability to defend itself.

Snakes do not dislocate their jaw in order to consume larger prey, but their jaws contain two halves which are not rigidly attached in addition to various other joints in their skull. These allow snakes to open their mouths very wide.

In an article written by Michael Schirber entitled “Deadly Aim: Cobras Really Do Shoot for the Eyes” Michael states “A spitting cobra can launch its venom well across the average dinner table.”

A cobra’s venom contains neurotoxins and tissue-attacking poisons. When these poisons make contact with the victim’s eye they will cause excruciating pain and possibly blindness. Researchers put some cobras through tests at the University of Bonn finding that cobras rarely miss, although they “cheat” a bit by shaking their heads from side to side as they spit.

If one is bit by a cobra they have more to fear than blindness because the poison interferes fatally with the respiratory system. Fortunately humans are not a cobra’s idea of dinner.

While you are probably aware that they are found in trees and in the sea, did you know snakes burrow underground?

Snakes regularly shed their skin, often leaving the discarded skin in one piece. This term is referred to as molting.

A pit viper has a unique thermal sensitive nasal pit which enables them to locate prey based on a temperature that is just a fraction warmer than their own. A snake collects airborne particles on its tongue and then passes them to a special organ in his mouth called Jacobson’s Organ which examines these particles, similar to the way that people smell.

There is over 3,000 varieties of snakes in the world, most of which live in warmer climates because the snake relies on the sun for most of its heat.

The Python can measure seven meters long, with a meter being approximately 39.3 inches.

The Brahiminy blind snake measures two inches in length and anaconda can reach a length of 38 feet.

The King Cobra’s venom is strong enough to kill an elephant.

Snakes do not blink. They do not have eye lids.

The Antiguan racer, a gentle brown harmless snake found in Antigua is in danger of extinction. Their eggs were eaten by the rat and Mongoose. The Mongoose also ate the snakes, the cattle trampled and civilization ran them out along with natural disasters such as floods and quakes.

A snake known as the paradise tree-snake soars through the air by flattening itself and balancing in the air much like a tight rope walker.

Being that there are approximately 3,000 varieties of snakes I am sure that there are lots more facts to be found, but I’ll leave you with these few.

    An enjoyable read. I once saw a snake swallow a rabbitt. I could hardly believe my eyes and it took a long time but the snake got it down.

    I know it’s part of the food chain, but I’d rather not see it.

    I really like the spitting cobra. They rarely miss? That’s a pretty accurate snake right there considering the target is rather small. Great research.

    WOW! Already knew to stay away from them but really hate them now. Glad we don’t have many to worry about here in Michigan.

    So Nick, jobs aren’t the only thing scarce in Michigan, huh? Well, at least we don’t earthquakes or tidal waves either. I think I’ll stay. lol

    Where I grew up, us kids used to find what we called garden snakes, those skinny harmless things. We used to catch them by the tail and whip them around and send them flying.

    Cruel? Perhaps. But so is spitting poison in your eye.

    Great article. Very interesting.

    Shelly, thank you for reading. Some how I can’t find sympathy in my heart for a snake. Other creatures, yes.

    Can snakes become man’s friend? We fear snakes unnecessarily. If we try to harm them knowingly or unknowingly it will react spontaneously. You did a great job in bringing out some amazing facts about snakes and their behavior.


  32. Judy Sheldon Says...

    Gijo, They may be fascinating, but I still don’t feel that they are friendly. lol

    interesting artical about snakes. i never that they could eat bits of their heart to stay alive.
    you get some beautiful coloured snakes, but i still wouldn’t keep one.


  34. Judy Sheldon Says...

    John, I don’t care how pretty their coloring is, I don’t want one either!
