Why Study This Topic?

  What I want to find out is the Boa Constrictor's habitat; it's length, ability, strength,and how dangerous it is. I want to know if it is easy for them to find food, and if it is, what do they eat? Why do I want to know this? I'll tell you. I think snakes are interesting, even if I think they're scary. Boa Constrictors sound amazing, and that's why I'd enjoy studying them.

What Was Already Known

  I already knew Boa Constrictors were dangerous. I knew they could wrap themselves around animals and suffocate them.They are likely to crush one's bones by doing this. Boa Costrictors are endangered probably because humans are scared of them and want to get rid of them. I know that Boa Constrictors are able to grow to be heavy snakes. These are snakes you don't want to meet up with in the wild.

Search for Information

  On the internet, I learned that Boa Constrictors are typically grey or silver with a series of brown or deep red saddles along their back. They are found in the warmest parts of the Americas, from Mexico to Argentina,and can reach lengths up to eighteen feet. Boas feed on birds, reptiles, and mammals. A Boa Constrictor will sieze its prey with his mouth, swiftly coil around it, and tighten its grip so that the victim can not expand its chest to breathe. Then, he will eat the victim.

 Boa Constrictors are some of the best known snakes. The Boa Constrictor gets its name from the way it kills its prey. It coils around the victim until it is smothered.

 The Boa Constrictor is one of the 50 different kinds of boas. They are closely related to the Pythons. The prey of Boas, whether warm-blooded or cold-blooded,is killed by constriction. Ordinarily, the snake places two or three coils of its body around the chest of the prey animal. Then, each time the victim inhales his breath, the Boa takes op more slack. After three or four breaths, there is no more slack, and the victim is swallowed by the Boa.

Description of Plant or Animal

  The Boa Constrictor are usually grey or silver with a brown or deep red pattern on their backs. They can be as long as eighteen feet and they can grow to be veryheavy. Boa constrictors are long and scaly. Their skin is often mistaken to be slimy. That is not true. The Boa Constrictor's skin is as dry as you can imagine. Like all snakes, Boa Constrictors have a transparent lens over their eyes. This is called a spectacle. Also like all snakes, Boa Constrictors shed their skin, leaving on them a shiny brand new coat of skin.

Habitat Requirements

  Boa Constrictors eat many things. They eat birds, mice, and other small animals. They live in jungles and forests. The chances of seein them are very small. The Boa Constrictor's shelters are usually under rocks or small caves. These habitats are in Mexico to Argentina. The Boa Constrictor gets its water from nearby streams, rivers, and ponds. In the winter, no matter if they live under rocks or in caves, snakes like the Boa Constrictor hibernate in caves.


  The Boa Constrictor's enemy is the jaguar. The jaguar actually eats the Boa Constrictor. Boa Constrictors are forest colors so they blend into the darkly forests that surround them. These colors are so the Boa Constrictor can hide from his enemies like the jaguar, or just from brave hunters that want to harm them.

Reasons for Endangerment

  Boa Constrictors are endangered because of predators, cold weather and believe it or not, humans. Humans cut down lots of jungles and forests where these snakes might live.They build lots homes, and by doing this, they are taking away the Boa Constrictor's homes. The Jaguar is the enemy that eats the Boa. The Boas could be endangered because the Jaguars are hungry. Also, it could be because of cold weather. Snakes are cold-blooded and could freeze to death in the cold.

 Ever since ancient times, reptiles such as snakes have lived on the earth. When humans started living on earth, snakes like Boa Constrictors were driven away because there were more bare places with no jungles or forests, and that meant endangerment to some of the snakes like the Boa. There was more pollution, noise, and less homes for the Boa Constrictors. So now, you can see why they're endangered. Sometimes, when you try to make the world a better place, you don't stop and think of what you are destroying.

Restoration Actions

  Many actions have been attempted to keep the Boa Constrictors. Some, like fighting, to not cut down so many trees, and not to build so many buildings. Everybody has a right to live, even the Boa Constrictors. Future actions could be to not have as many hunters, (so they won't shoot the Boa Constrictors) and to learn to care for them so you convince people not to harm them in any way.

What Was Learned

  I learned many things about the Boa Constrictor. Where it lives, its features, how it lives,(all mentioned above) and many other things. I am glad I learned this much because I think it is important to learn about wildlife so you can understand even more than you already do. I learned that the Boa Constrictor will not necessarily attack you, but is more likley to attack his victim.

Conclusions From Research

  From learning about the Boa Constrictor, I can tell people about them and they could try to help keep them around. This research can help me by understanding Boa Constrictors more and what they feel like. I can understand that sometimes they might be as scared of humans as humans are scared of them.
