How to Identify Types of Pythons and Boas

Because boa constrictors, reticulated pythons and anacondas are some of the biggest snakes in the world, many people get confused about which is which. The first thing to note is that the anaconda is a species of boa, not a separate type of snake. That leaves two groups, the boas and the pythons. These snakes have some things in common: they are constrictors, killing their prey by wrapping around it and suffocating it, and they are considered primitive snakes with two lungs (most snakes only have one) and remnants of hind legs and pelvic bones. But they have differences, too. Pythons have one more bone in their heads than boas do and some additional teeth. Pythons are found in the Old World (Africa, Asia, Australia) while boas live in both the Old World and the New World (North, Central and South America). One of the biggest differences is that pythons lay eggs while boas give birth to live young.

  1. Pythons

    • 1

      Start with the rock python, it is a non-venomous python species found in subsaharan Africa. This is is one of the world's largest species of snakes. Adults can reach lengths of over 20 feet. They are typically brown in color, with olive green and tan irregular blotching, fading to white on the underside. At a glance, they can be easily mistaken for the Burmese python but the two species are not closely related.

      Commonly referred to as the royal python, the ball python is non-venomous and is found most in Africa. It gets its name from its tendency to curl into a ball with its head on the inside when intimidated or frightened. Thousands of ball pythons are imported to the United States every year to be sold as pets. It is typically light brown-green or black in color, with a tan-yellow underbelly. However, ball pythons come in many "morphs," which are genetic mutations that alter the colors and patterns of the scales. Adults range in length from 3 to over 6 feet.

      Found in Australia, the black-headed python can grow up to 9 feet long. They have a distinctively skinny head with black scales covering it down past the pythons neck. The black-headed python will hiss loudly when disturbed but is unlikely to bite unless attacking food. They will sometimes strike with a closed mouth in defense, but usually are easily handled without incident. Black-headed pythons have been known to sleep for long periods, thus making them appear to be lethargic or lazy.

      Referred to as a blood python, the Borneo python is a wide bodied breed of python and can reach lengths of up to 7 feet and can weigh up to 30 pounds. Borneo pythons have had a reputation in the past as being mean tempered. As of late, many of the captive Borneo pythons bred for pets have been noted as being very easy to handle and are now a good choice of pet for the knowledgeable owner.

      Found in Australia and New Guinea, the carpet python is a medium to large snake. Most carpet pythons are nocturnal. There are at least seven subspecies of carpet pythons. Carpet pythons are often referred to beginners as an ideal first pet snake. Although carpet pythons can grow to 6 to 16 feet and can be nippy as hatchlings, most will grow into docile, trustworthy adults. Males are typically smaller than females of the same species and are a wise choice for those looking for a slightly smaller adult.

      Getting its name from nineteenth century zoologist, John George Children, the Children's python comes from northern Australia. The Children's python is a relatively small snake averaging around 3 feet in length. The Children's python is considered a good pet for people who are inexperienced with snakes because of their good disposition and small size. Children's Pythons generally live for 25 to 30 years depending on how well they are cared for.

      Found in the forests of New Guinea, the green tree python is a tree dwelling species. The most typical adult phase is a bright green, although blue or yellow examples are occasionally found. A series of white or blue dorsal and/or later spots is evident on most. Sometimes these light areas form an intermittent line down the dorsal surface. They may reach 7 feet. This is fairly slender snake, so a specimen coiled cinnamon bun-style across a branch may appear smaller than it actually is.

      The reticulated python is the longest species of snake in the world. These pythons are the longest but not the largest species of snake. Reticulated pythons are known to have very high intelligence compared to other species of snakes.
