Boa constrictor is able to produce eggs even when male is not available, via process called parthenogenesis (development of embryos from unfertilized eggs). Gestation period lasts 100 to 120 days and ends with 10 to 65 babies (25 on average). Although large, boa constrictors are smaller compared to most python species asides from Ball Pythons, that is. However, boa constrictors of 13 ft to 18 ft have also been reported. The full-grown female snakes are usually 2.1m to 3m or 7ft to 10 ft long. Boa constrictor is ovoviviparous species, which means that female gives birth to live babies. Generally, a mature male grows between 1.8 m and 2.4 m or 6 ft and 8 ft. Baby pythons usually emerge from the eggs 2 to 3 months later. Female curls her body around eggs and shivers to generate heat essential for the successful incubation. Boa constrictor usually eats medium-sized mammals, possums, monkeys, wild pigs, bats, lizards and birds.

Diet of most pythons is based on birds, rodents, civets and small primates. Physical differences include the head scalation and the location of the heat pits around the mouth. Small pythons consume animals that are roughly the size of a house cat, while larger pythons hunt and eat bigger animals such as deer or antelope. It usually resides near the streams and lakes. Python is terrestrial creature and excellent swimmer. They often hide inside hollow logs and abandoned burrows of various mammals. Young snakes often climb trees, while adults spend their life on the ground. Its teeth are small and hooked.īoa constrictor is semi-arboreal animal. Boa constrictors has less teeth than python.

In pythons, but not boas, a pair of upper jaw bones called the “ premaxilla” bear teeth.Īt this point, you might be wondering where anacondas fit into all this. Also, the two families sport slightly-different body plans. Boas tend to bear live young, whilst all known pythons are egg-layers, with gravid mothers sometimes squeezing out over two dozen in a single clutch. For instance, just when everyone thought Florida couldn’t get any wilder, the enormous Burmese python ( Python molurus bivittatus) began populating the Everglades during the 1980s, thanks largely to irresponsible pet owners.Īnother decent rule of thumb is reproduction. Note, however, that human globalization has helped many species artificially spread out and invade distant lands. It is the worlds longest snake, and the third heaviest after Green Anaconda and Burmese python. While pythons are Old World snakes, boas also dwell in the Americas. The reticulated python (Malayopython reticulatus) is a python species native to South and Southeast Asia. But how can you tell them apart? And from which family does “your” serpent hail?īefore breaking out the field guide, take geography into account. Since the world’s most heavily-built snake species are all either boas or pythons, this reptile probably belongs to one of those groups. In the film, an FBI agent seeks help from a herpetologist and a marine biologist to release a specially bred Boa to hunt a gigantic Python that has been attacking humans.
