![]() For instance, when the blood pressure cuff was constricting them a third of the way along the body, they breathed using ribs further back – specifically, they swung these ribs backward while tipping them up to draw air into the lungs. The boa constrictor is a member of the family Boidae.The species is native to tropical South America. They found that boa constrictors could control the movements of ribs in different areas of the rib cage independently by activating the musculature around specific ribs. The boa constrictor (scientific name also Boa constrictor), also known as the red-tailed boa, is a species of large, non-venomous, heavy-bodied snake that is frequently kept and bred in captivity. “Either the animals did not mind the cuff, or became defensive and hissed to try to get the researcher to leave,” says Capano, explaining that the reptiles really fill their lungs when hissing: “this was an opportunity to measure some of the biggest breaths snakes take.” They used X-rays during this process to see how the snakes’ ribs moved. ![]() The wince-inducing scene was filmed in Brazil these types of snakes like tropical climates. They then positioned a blood pressure cuff over the ribs in the regions of the metal markers and gradually ramped up the pressure to immobilise them. Footage was released showing a boa constrictor, one of the largest snakes in the world, writhing in pain after attacking a porcupine and getting pierced by its spikes and the video itself is even painful to watch. The researchers attached tiny metal markers to two ribs in three adult female boa constrictors, one a third of the way along the body and the other in the middle. Their lifespan of 20 to 25 years requires a longtime commitment of owning such a pet, so when. Unlike other species, the male boa constrictor is usually smaller than the female. They normally do not exceed 60 pounds in weight. A section of a boa constrictor in contact with a table, breathing using the ribs either side of the region contacting the table. The boa constrictor ranges in size from 5 to 10 feet long when mature, so their housing needs to be of a large scale. They can even use the hind section of their lungs like a bellow, pulling air into the lung when the ribs further forward cannot move. The study shows that boa constrictors can move only specific segments of their ribs, allowing them to breathe with certain segments of their lung when others are hindered by constriction. “With no diaphragm, they rely entirely on motions of their ribs,” says lead author of a new study, research scientist in the Department of Ecology and Evolutionary Biology at Brown University, USA Dr John Capano. ![]() Using different regions of the rib cage when inhaling had been considered, but no one had monitored in detail boa constrictor breathing patterns while they throttled their next meal. ![]() And, until now, it hasn’t been clear how modern snakes save themselves from suffocating while eating. In what’s clearly a growing field of study, scientists recently explained how whales don’t drown while eating. ![]()
