Reptiles found in the Kruger - The African rock python

The African Rock Python is the largest of all snakes found slithering around in Africa and may reach or exceed an impressive length of 6 metres (20 ft). However, males from this non-venomous species of snake, usually reach 5 metres while female reach 4.25 metres in length. There are two subspecies of this incredibly large snake; one is found in Central and Western Africa while the other is found in parts of Southern Africa. The species from Southern African is generally smaller than its relative living in Central and Western Africa.

This snakes' thick body is a grey-green or brownish colour covered in blotches, ranging from a mix of brown, olive, chestnut to yellow colours, often merging up into a wide and asymmetrical stripe. On the crown of their heads they are marked with a large spearhead shape while a triangular shaped marking of dark and light bands run from each eye to their lip. Their scales are small and smooth and their teeth sharp and curved backwards, delivering a painful bite anchoring into the victim, that if left untreated may lead to a nasty infection. Pythons have two functioning lungs unlike the majority of snakes only have one. They also have small and visible pelvic spurs which are believed to the remains of hind legs from prehistoric times. 

Habitat

Both sub-species are found in sub-Saharan Africa, with Northern African rock pythons living in parts of Central and West Africa and the Southern African rock python found living in parts of Southern African countries such as Kenya and South Africa among others.

Depending on which subspecies of African rock python, they live in a wide range of habitats, which include savannahs, woodlands, grasslands, forests, semi-deserts and rocky areas, avoiding very dry desert areas. They often live in areas where a permanent source of water can be found such as swamps, lakes or along river banks.

Behaviour

They are solitary animals and will only seek out other pythons during breeding season. Due to their large size they mainly stay on ground but are able to climb if need be. They are great swimmers and can even stay submerged under water for long periods of time. Although mostly nocturnal they will bask in the sun during the day soaking in the sun’s rays for thermoregulation purposes. These snakes have a reputation for being aggressive and unpredictable, and will bite and constrict if feeling very threatened or unable to escape.

Diet

The African Rock python has heat-sensitive pits positioned near their lips, which are used to detect the location of warm-blooded animals that could be potential prey and are even able to pick up their location in the dark.

After capturing the prey, the python coils around it, tightening its grip with each breath of the victim, causing crushing of internal organs and suffocation; this method is called constriction. It will then eat the prey whole which leads to large meals taking months to digest.

They have a carnivorous diet, feeding mostly on large rodents, monkeys, warthogs, antelopes, fruit bats, monitor lizards and even crocodiles in the wild but if they find themselves in suburban areas they will eat rats, poultry, dogs and goats.

Reproduction

Once reaching the age of sexual maturation between 3 to 5 years, African rock pythons seek out one another when the mating season arrives in spring. Females lay between 50 to 50 hard-shelled, elongated eggs in the safety of an old animal burrow, termite mound or cave. 

She coils around the eggs in order to protect them from predators till they hatch around 65 to 80 days later. The mother will also guard her python babies from predators for up to 2 weeks after hatched. Juvenile African rock pythons appear like duplicates of adult pythons expect more brightly coloured.

These carnivorous snakes are preyed upon by hyenas, wild dogs and big cats such as leopards.
