5 COMMON Types of Snakes Found in Rwanda! (2023)
Do you want to learn about the types of snakes found in Rwanda?
If so, you have come to the right place. In the article below, I have listed the MOST COMMON snakes you can expect to see. Unfortunately, there are so many snakes that live in Rwanda that it would be impossible to list each one. 🙂
You’ll see that the snakes in Rwanda are very different from each other. They range from venomous species to snakes that use constriction to immobilize their prey. In addition, certain snakes are common to find living around people. For each species, you will find out how to identify that snake correctly, along with pictures, interesting facts, and RANGE MAPS!
5 types of snakes in Rwanda:
#1. Puff Adder
- Bitis arietans
Also known as the African Puff Adder and Common Puff Adder
Identifying Characteristics:
- Adults are 100-150 cm (39-59 in) long.
- They are commonly gray to dusty brown, with yellow chevrons on their backs.
- There are two dark bands on the head, one on the crown and one between the eyes.
- Male Puff Adders are usually larger than females.
Puff Adders are one of the most dangerous snakes in Rwanda.
This ill-tempered native snake roams savannas, grasslands, and – to the great misfortune of inhabitants – densely populated areas. The Puff Adder gets its name from how it inflates itself when threatened. Instead of moving away, it will hiss a warning to intruders before inflating and striking.
Its distinctive chevron pattern in yellow, white, and brown colors allows the Puff Adder to blend into its surroundings. This camouflage is particularly useful for its lifestyle as an ambush predator. Be careful where you wander because this highly-venomous, fast-striking snake seems to come out of nowhere.
The Puff Adder’s venom contains a cytotoxin that can kill a healthy adult human within a day. Their potent venom and tendency to loiter around footpaths make this snake one to avoid. Watch your step!
#2. Spotted Bush Snake
- Philothamnus semivariegatus
Also known as Spotted Green Snake and Variegated Green Snake
Identifying Characteristics:
- They are typically 60-130 cm (24-51 in) long.
- Spotted Bush Snakes have small heads, golden yellow eyes, and blue tongues.
- The upper half of the body can be yellow, green, or blue, while the tail-end is brown. You might also find black spots or stripes.
You might encounter the Spotted Bush Snake in Rwanda in forested areas or suburban gardens.
These beautifully-patterned snakes have keeled, or ridged, belly scales, allowing them to easily climb walls, trees, and bushes. Curiously, they’re fantastic swimmers as well!
Often misidentified as the more dangerous Green Mamba, Spotted Bush Snakes are non-venomous and harmless to humans. Instead, they’re patient hawk-eyed hunters, staying completely still before swiftly attacking lizards, geckos, and frogs in daylight.
Spotted Bush Snakes are alert, nervous animals and will immediately flee upon sensing danger. They don’t have established territories and are noted to travel far and wide in pursuit of their prey. So if you find one astray in your home, leave a window open, and it’ll leave soon!
#3. Red-lipped Snake
- Crotaphopeltis hotamboeia
Also known as Common Herald Snake, White-lipped Herald Snake, Savanna White-lipped Snake, Black-templed Cat Snake
Identifying Characteristics:
- This snake can grow to 70-100 cm (28-39 in) long.
- Coloration is usually olive green or gray on the back, sometimes speckled white. Its head is notably black.
- True to its name, it has a bright red (sometimes orange or yellow) upper lip most prominently displayed when it feels threatened.
- The head is broad and triangular, while the tail is short.
You’ll find Red-lipped Snakes near marshlands, bogs, and lowland forests in Rwanda.
They also gravitate towards the suburbs, so you might bump into one in your backyard after an evening rain.
Most active during the night, these land snakes prey on amphibians such as toads and frogs. Their venom is mild, effective only on their chosen prey, and harmless to humans. They also have a mild and shy demeanor.
Don’t test your luck, though. Red-lipped snakes have a trigger-happy temper when provoked. So even though its venom isn’t dangerous, its bite is still painful!
Interestingly, the Red-lipped Snake got its other common name, the Herald Snake, from a newspaper story. It was first mentioned in the Eastern Cape’s Herald newspaper!
#4. Central African Rock Python
- Python sebae
Also known as Northern African Rock Python
Identifying Characteristics:
- Adults reach impressive lengths of 350-750 cm (138-295 in).
- It has two noticeable lines from the nose to the back of the head.
- Striped blotches decorate the body, colored olive, brown, or yellow.
- There is a distinct yellow inverted “V” marking under the eyes.
The Central African Rock Python is the longest snake in Rwanda!
Found near bodies of water, this heavyweight python enjoys environments such as forests, savannas, swamps, and semi-deserts.
Central African Rock Pythons may be non-venomous, but don’t let that give you a false sense of security. This species is strong enough to kill a human with its powerful constriction. Additionally, they routinely swallow antelopes, monkeys, and monitor lizards whole.
Unlike most snakes, Central African Rock Pythons are protective mothers. They fiercely guard their nest after laying eggs, protecting their young from predators and lashing out at unsuspecting passersby. They’re even known to be territorial of a nest after the eggs have hatched!
#5. Brown House Snake
- Boaedon fuliginosus
Also known as the Common African House Snake, Sooty House Snake, Black House Snake, Olive House Snake
Identifying Characteristics:
- Adults average a length of 60-150 cm (24-59 in).
- Juveniles are solid black, while adults are dark brown or gray with faint stripes and spots.
- The scales are smooth and iridescent, appearing white when they reflect light.
- Its body is thinner at the sides.
The Brown House Snake is one of the most common snakes in Rwanda.
Its name hints at its habit of visiting homes, which is where most people see this species. However, this nocturnal snake can also thrive in woodlands, savannas, scrublands, and grasslands.
Brown House Snakes seek small mammals and reptiles as a food source. They put their prey into a stranglehold and swallow them whole without chewing. They particularly enjoy mice, so if you’re dealing with an infestation, these snakes might be nearby.
Luckily, the Brown House Snake is non-venomous and timid. It’s likely to flee or curl up tightly into a corner if threatened.
