The aroused males could have been having a sexual romp with each other before the snake became entangled. “It could have been something to rub on.” “It could have been sexually stimulating for them,” said Diana Reiss, a marine mammal scientist and cognitive psychologist at Hunter College in New York who was not involved with the study.

In this case, the team did not see where the snake ended up. Other than a single case of cannibalism, researchers haven’t documented the serpents being eaten.

The python is what’s known as an old-world snake. Reichle says Bolivian river dolphins usually swim below the surface, and sightings often catch only a fin or a tail. Another main difference between the boa constrictor and the python is that they evolved in different geographical locations. Their lifespan in the wild is about ten years.Dr. Baby snakes are about 2 feet long when they are born and are almost immediately able to swim and hunt. Reproductionįemale anacondas retain their eggs and give birth to two to three dozen live young. Jaws attached by stretchy ligaments allow them to swallow their prey whole, no matter the size, and they can go weeks or months without food after a big meal. Anacondas are nonvenomous constrictors, coiling their muscular bodies around captured prey and squeezing until the animal asphyxiates. They reach their monumental size on a diet of wild pigs, deer, birds, turtles, capybara, caimans, and even jaguars. Their eyes and nasal openings are on top of their heads, allowing them to lay in wait for prey while remaining nearly completely submerged.
