The early ones are believed to be related to aquatic reptiles but through evolution they have changed to what we see today. They come in all sizes and colors and they can be found in variety of environments. There are over 3,000 know snake species to learn about. Not all of them are venomous of them only about 375 of the offer venom. All species of them are reptiles; they offer a body that is very flexible. They do not have limbs but that is not an obstacle for them from being able to climb or to slither along on their bellies, some of them are only a few inches long and others are more than twenty five feet in length. They are able to live in trees, on land, and underground. They prefer to be in climates that are humid and that offer a warm temperature.

Snakes

...“The Rattler”, a man and a rattle snake cross paths in the desert, and life vs. death is involved. The man has to decide whether he should kill the snake or not, and he decided that he is obligated to. Though we understand both sides of the story, the man should not have killed the snake. The snake was calm and alert, not trying to harm anyone, but still protecting himself. In the short passage, “The Rattler” , the personification of the snake, the point of the man, and details about the setting all lead readers to feel sympathy toward the snake, as well as sorrow and frustration towards the man. Readers feel sorry for the snake because it loses its life, even though it never threatens or causes the man any harm. The snake is calm. The snake is careful and watchful, but does not strike. The rattler had not moved; he lay there like a “live wire”. The snake has all potential to harm, but controls itself, not threatening the man. The snake even gave the man a second chance by hiding in the bush, as if saying “I don’t want to harm you, but I can, so leave me alone!” As we all know, snakes are very much able to harm, but the snake, being calm, chose to even hide in order to not harm the man. Readers can also see that the snake is very patient. The snake was patiently waiting for the man to “show intentions”. Instead of automatically striking, it decides to wait, to only harm as self-defense, so that he does not have to harm for no reason. The snake is unwilling to fight, unless absolutely...

Hunting Snakes

...Hunting Snakes Snakes were an integral part of my childhood experience, and I am always surprised to remember that not everyone grew up being so aware of snakes. The most common snake around Texas is the rattlesnake. Well, actually I don't know that. I just know that my father talked a lot more about the rattlesnake than he talked about any other snake. They were both the bane and perhaps the reason for his existence. Dad tended to shoot rattlesnakes whenever he saw them, and he sometimes told the story about seeing a snake from his pickup window, stopping the truck and reaching behind the seat for his shotgun, then starting to load a shell into the gun (he always kept gun and ammunition separately) and realizing that he only had one shot gun shell with him. That made the shot more important because he knew he would only have one opportunity to shoot the snake. Then, suddenly, he saw a second snake next to the first, and realized that he was seeing two full grown rattlesnakes in some sort of mating ceremony. He carefully slid his one shell into the gun, and watched. The snakes neared each other. They seemed to meet eyes. They seemed to fall in love. They started a slow, sensuous movement, moving their bodies in the dust in strange, swirling S patterns. Then they reared up, their heads close together, their eyes locked in love. Bam! My father shot his one shell, and neatly blew both snakes' head off. Such are the tales I grew up on. Doesn't it make a strange sort...

Snakes and Evolution

...Snakes and Evolution September 4, 2013 BIO/101 Snakes are reptiles that have been on Earth for over millions of years. Snakes are a peculiar creature because the true origin of snakes is unknown. The delicacy of their structure allows for error in fossil records, because many of the first fossil records of snakes are incomplete skeletons. A fact known to be true is that snakes were legged vertebrates. The structure of a snake may be complex, but it is suited for survival. This fact changes factors such as food, shelter and survival, thus the evolution of snakes. Fossil records of snakes date back to the crustaceous period. This era signified the end of dinosaurs but there is evidence of snake life in this era. An interesting fact is that dinosaurs are descendants of cotylosaurs which then produced Diapsids, so snakes are not direct descendants of the dinosaur, but they are evolutionary cousins of Tyrannosaurus and Triceratops. During this era all the continents were together as one, and they were called Pangea. The shuffle of all the continents caused snakes to adapt to the new environmental changes, and strive to survive through natural selection. According to the Bible, snakes were forced to give up their legs and slither on their belly because of mischievous doings. This may be a story or fact but fact is that snakes had legs at one point in time. The first records of legged snakes were found in the Middle Eastern. Another record of a...

These non-venomous snakes can grow anywhere between two and four feet and are typically tan or grey in colour. It is common for them to have dark brown or black stripes leading horizontally down the body. As snakes get older, they are often a solid dark brown or black colour10.

Com/155 Exotic Pets Paper

...variety of exotic pets to choose from, have you ever considered a making a snake your choice? The two most popular snakes to buy are red-tail boa constrictors and ball pythons. These snakes are similar, but there are underlying differences that make the choice to buy one or another very important. Ball pythons and red-tail boa constrictors have many things in common with each other besides the obvious point that they are both snakes, both suffocate their prey, and both are reptilians. These snakes are both known for being very docile creatures. When handled on a regular basis, these two species of snakes are not known to be aggressive. When you think about it, no one would want to stay in a cage all day every day. A regular basis does not have to mean daily. A regular basis is just about constancy. If you are going to let your snake out of its cage twice a week, you need to make sure you stick to this regimen. Another way that ball pythons and red-tail boas are alike is their habitats. These snakes are good about regulating their own body temperature, but they need a little assistance from their owner/caretaker. The tank that you place them in, as their home, needs to have a cool side and a heated side. This can easily be done with the purchase of temperature measuring strips and a heated lamp. Placing the heat lamp and one strip on one side and just the second strip on the other side of the cage, the snake has the ability to slither to either side to regulate its own body temperature...

Burmese Python Research Paper

...The Snakes That Are Destroying the Everglades If you had a pet Burmese python that grew too large, would you release it into the wild when you could not take care of it any more? First, you need to know what a Burmese python really is. The Burmese python is a snake originally from Burma (now Myanmar) which can grow up to lengths of almost 25 feet, weigh over 200 pounds, and can eat an alligator, or even a full grown human, whole. They are an invasive species in the Everglades. The presence of the Burmese python is changing the Everglades by Invading the ecosystem, impacting the environment, and bringing tourism. First, Burmese pythons are invading the ecosystem. Most of the Burmese pythons living in the Everglades are there because of bad decisions made by idiotic people. Some people at one point decided to get a Burmese python, ignored the fact that it would one day get too large, and when that day came, released the python into the Everglades (Source 1 paragraph 3). Basically, that means that people allowed a species to invade a complex and fragile ecosystem. Also, these snakes are destroying the natives animal populations by eating more than the environment can handle. This basically means that the Burmese python could very well replace other species of animals by eating them away. So far, the damage to the...

A Cry for Help

...blanket that sat on the ground, wrinkling it up as he went. Little did we know we were about to be called upon by the Lord above to do a little bit of something new today. It was time for our weekly picnic that we always had with each other and my dolls. Just as we were finishing up our creamy peanut butter and grape jelly sandwiches we heard a loud shrill, “HELP! GET IT AWAY FROM ME!” I looked immediately over to Fuzzy and we sprinted across the tree-lined trail to my grandmother’s home. We came upon her standing on a green plastic lawn chair with a large wooden shovel in her hand. “Grandma, what is wrong?” I shouted from afar. “It’s a snake! There is a snake in the flower bed!” she panted out frantically. Being the rebel I was, I strolled over there rolling my eyes at my grandmother’s silly sense of panic and began searching for the snake. If only I could go back in time and do what any regular kid would do when they sense panic in an authority figure. I would have sprinted the other direction in a heartbeat. I ran to the distress call of my grandmother only to find her weeping in the corner of the yard. “Heavenlee, listen to me, call the police,” she said with a quivering voice. This made me shudder just a little bit. My grandmother was a strapping almost six foot tall, broad shouldered, rugged to the bone woman. I had always looked up to her for her very presence was menacing. She was the embodiment of the word tough. So, to see her whimpering, then revert to a fetal position...
