2009). The first actual record of Burmese python was in 1979 in Everglades National Park, however the first established populations were recorded in 2000; at this point causing an increase in attention and investigation of these invaders. Burmese pythons can reach up to five and one half meters which is approximately 18 feet, weigh up to 150 pounds and a female can produce anywhere from eight to 107 eggs. The diet of pythons range from mammals, fish, amphibians, birds, and even other reptiles. Although they are not venomous they are powerful biters and constrictors. It has yet to be determined the mean at which these reptiles were introduced to South Florida through either intentional release via the release of unwanted pets or the accidental release: the escape of pets or even the media speculated event of Hurricane Andrew 1992 causing the release of snakes out of a snake sanctuary (has yet to be …show more content…
It has been estimated that there approximately 30,000 of these reptiles living in South Florida measured by density; the population ranges throughout Everglades National Park as far south as the Florida Keys. A series of experiment were done to determine the eating habits of these predators: a roadkill study and stomach content examinations in particular. In the roadkill study, surveyors not only showed a decrease in the amount of roadkill seen, but decrease in overall mammal encounters as well. According to Dorcas et al., there was a 99.3% decrease in the observation of raccoons, 98.9% decrease in the observation of opossums, and an 87.5 decrease in the observation of bobcats. When stomach contents were examined the following were found mammals (ranging from small: raccoons, opossums to large: deer, bobcats), birds (over 25 different species), amphibians, and even fellow reptiles (an occasional alligator). According to the stomach content examination by Dove et al. 25% of the Burmese python collected between the years of 2003 and 2008 there were bird remains found their digestive tract. Their broad diet has led to competition with native species; in some cases even becoming a threat. The consumption of these animals not only effects the animals that are being consumed, but the other animals

...soon after purchasing a juvenile exotic reptile. Unfortunately, for many pet owner’s, the answer is to release the pet into our neighborhoods and parks creating a multitude of problems for homeowner’s, State officials and the environment. Probably the best known pet to become a predator is the Burmese python, also known as the Indian python. Burmese pythons average approximately 13 feet in length, but can grow to over 20 feet. (Indian Python) Their weight may exceed 200 pounds. Most owners begin feeding their juvenile pythons mice, but a snake grows quickly and graduates to rabbits, chickens and eventually pigs. A full grown python requires a cage of at least 8 feet in length. Because a Burmese python has a life expectancy of over 20 years, the potential buyer must carefully evaluate the long term commitment required with this purchase. Another well know pet to predator is the Nile monitor lizard. These lizards average 4 to 6 feet in length, but can soon grow to 7 feet. They are a carnivorous lizard that as a juvenile begins eating crickets, then graduates to gold fish and later to rats and other small animals. When full grown, monitor lizards like the Burmese python, need an enclosure of at least 8 feet, however, it is recommended that they have their own room. Because they are water lizards, an owner should also provide a monitor lizard with a small swimming pool. The Nile monitor lizard can live 10 to 15 years. Again, a potential buyer must evaluate the long...

Burmese Python In The Everglades

...Burmese Pythons Have you ever went to the everglades before? If so then you’ll realize how much Burmese pythons they’re in the Everglades. Now the first thing you’ll be thinking of is Burmese pythons not belonging here in Florida and should be in Southeast Asia where they’ve originated but here is where I get into detail about this. First off, what is a Burmese python? “The Burmese python is a magnificent and powerful animal”. “Native to the grassy marshes of Southeast Asia”, capable of growing to an astounding length of 23 feet and a weight of up to 200 pounds”. (Paragraph 1 of Burmese Python: The Snake That’s Eating Florida). Also Burmese pythons are carnivores and survive by eating small birds and mammals. Although they got no venom, they kill their prey by grabbing the prey with its back teeth and when the prey tries to run, it only sinks further into the python’s grip and then the python wraps its body around the body and squeeze until the animal is dead which then the python swallows the prey by its unique hinged jaws which allows it to swallow an object five times as wide as its own head....

Burmese Python: The Invasion Of The Everglades

...Burmese Pythons Soon it would become a deserted wasteland. To us, we see the Everglades as a beautiful swampland that’s home to many animals. However, the truth is hidden. The Everglades is slowly dying. Its wildlife is reaching extinction. What is to blame? The invasion of the Burmese Python. The presence of the Burmese Python is ruining the unique Everglades. The Burmese Python is 23 feet in length and can weigh up to 200 pounds. It has a beautifully patterned skin. The python can devour up to anything that is 5 times as wide of its gaping mouth. It mostly feeds on small mammals. Its method of eliminating its prey is by grasping its prey with their fangs. If the animal tries to struggles to break free, the fangs sink only deeper. The python slowly starts wrapping its body around the struggling mammal and squeezes it until its last breath. The python then swallows it whole.

Essay On Burmese Python In The Everglades

...The Burmese Python in the Everglades What is 23 feet long, as wide as a telephone pole and eating up the Everglades? Why, it is the Burmese python. First, the python is different from other snakes. Secondly, it has had a massive effect on the area it has invaded. Thirdly, it has gotten there through many means. And finally, we are helping to stop this invasion. The invasive Burmese pythons are leaving a wake of destruction in the delicate ecosystem of the Everglades. First, we need to understand the structure of the Burmese python. The Burmese python is powerful, and with its massive strength can eat anything to soothe its appetite. Among the largest snakes in the world, the python can be as long as 23 feet and sport a girth as wide as a telephone pole. This carnivorous snake has no venom and instead relies on its strength and back-curving teeth to take down its prey.

Burmese Pythons In The Everglades

...Burmese Pythons are an invasive species in the United States. Since inception, they have rapidly overwhelmed the natural wildlife to become the dominant species in Florida’s Everglades. According to Florida’s Python Hunt, “Tens of thousands of Burmese Pythons are estimated to be living in the Everglades.” To contain their rampant numbers, various initiatives have been introduced. A month-long hunt has been sanctioned by the State of Florida and the Fish and Wildlife Commission. This draws in large numbers of hunters - experienced and inexperienced alike - to the Everglades. The huge influx of hunters brings with it many unique challenges to both the natural habitat and humans. The Burmese Python, native to southeast Asia, can grow up to 23ft. and weigh up to 200lbs. Although these snakes have no venom, that doesn’t make them harmless. Their remarkable hinged jaws enable them to consume prey five times the width of their head. Even though the Burmese Python has the ability to swallow a victim larger than it’s head, that doesn’t mean that these Pythons ignore small prey. Along with mammals, The Burmese Python mainly lives off small birds. With no common predator, these creatures will continue to eliminate the native...

...Today in South Florida, we face an invasion from a silent and slithery enemy, the Burmese python.   To give everyone some information on the reptile I did some fact finding on the internet (Wikipedia) to get some basic information on the size of this animal, wow was I amazed at the results.   The most important item I was curious about was; is this animal venomous, which it is not.   Hurray for us on that one. However, the Burmese python is one of the largest snakes in the world; it reaches lengths of up 23 feet and weights of over 200 pounds.   The largest python found thus far in the Everglades was 16 feet long and weighed 152 pounds.   Hatchlings range in length from 19-31 inches and can more than double in size within the first year.   Burmese pythons are light colored with dark brown blotches bordered in black, and a pale belly.   They grow much longer and heavier than any of Florida's native snakes the largest is the indigo snake that grows to 8.5 feet.       It is estimated that these reptiles are escaped or discarded pets.   State rules that went into effect this year should help prevent those less ethical individuals from dumping these creatures into our beloved eco system.   The laws include a $100 annual permit to own “reptiles of concern,” and a mandatory microchip.   Nevertheless, it is imperative that more be done to educate people about the problem of turning loose non-native species. In the past several decades, this species of reptile has thrived in the warm...
