Available statistics show that there are 101 known species of snakes in Rwanda, seven of which are extremely venomous and considered life-threatening. Six of the venomous species can be viewed at the Kandt House Museum.
Named after Richard Kandt, a German physician, explorer, and writer believed to be the first European to have thoroughly documented the geography and wildlife of Rwanda, Kandt House Museum is located at his former residence in the heart of Kigali.
A snake and crocodile exhibition at the facility is regularly held to help educate the general public about human-wildlife interaction.
A large section of the museum is dedicated to showcasing Rwandan life in all aspects â€" social, economic, and political way even before the colonial times.
Richard Kandt is famous for using his explorations to serve as the first resident of Rwanda under German colonial rule and his administration laid the groundwork for the German colonial presence in the region.
Here are the venomous snakes housed at the Kandt House Museum:
1. Puff Adder
Puff adders are highly venomous snakes found in savannahs, grasslands, and rural farmland in Rwanda and most parts of Africa.
Hendrik Hinkel, a snake curator at the Richard Kandt House Museum, says that puff adders are responsible for most snakebite fatalities in Africa due to various factors, such as wide distribution, frequent occurrence in highly populated regions and their aggressive disposition.
"One thing that makes puff adders common is their tolerance to humans, unlike other snakes that live primarily in rainforests," Hinkel explained during a visit by iGIHE.
He revealed that puff adders possess cytotoxic venom, which damages cells and tissues at the bite site, causing pain, swelling, blistering, and tissue destruction. In severe cases, this can lead to necrosis (tissue death) and potential loss of limbs, such as fingers or toes.
These snakes vary in colour ranging from sight yellow to dark brown, synonymous with their habitats. They have characteristic 'V' shaped markings that run from top downwards the snake's rib cage. Their heads are triangular in shape, a common characteristic for most venomous snakes.
When endangered, the snake powerfully exhales, creating a loud hissing sound.
Puff adders are ambush predators that feed on a variety of prey including birds, mammals, lizards, frogs or any remains of animal flesh.
2. Forest twig snake
The Forest twig snakes possess hemotoxic venom, which affects the blood and tissues. The venom can either coagulate the blood or liquefy it, causing severe bleeding.
Forest twig snakes have a slim, brown coloured body with dark marks in the shape of a twig. The head is also often slim with a pointed snout and glittering eyes. The top of the head is usually green and the bottom orange for males and cyan/white for females.
When threatened they puff up their throat and are usually seen hanging in branches vertically with their heads facing downwards.
Their prey of choice are lizards and chameleons but they also eat frogs, fellow snakes and wild birds.
3. Black mamba
The black mamba is a species of highly venomous snake belonging to the family Elapidae. The snake is known for its aggressive nature when endangered. It often rears up and strikes multiple times.
A black mamba possesses a highly potent neurotoxic venom that attacks the human central nervous system. The venom delivery is rapid due to long fangs and powerful muscles.
Ironically, the black mamba is not black in colour. Normally, it's typically grey or dark brown, with a lighter underside. Its name originates from the black interior of its mouth.
This is one of the longest venomous snakes in the world and can grow up to 4.3 meters (14 feet). Its preferred habitat is thick savannas, woodlands, and rocky hills.
The black mamba primarily feeds on small mammals, birds, and reptiles.
4. Rhinoceros viper
The Rhinoceros viper derives its name from the distinctive horn-like scales on its snout.
The snake's venom is basically hemotoxic, although it also exhibits some cytotoxic properties.
These types of snakes are heavily coloured and patterned, with shades of green, yellow, blue, red, and black in various shapes and lines. Most notably, they have a pair of small horn-like structures protruding at the top of their snout.
Their heads are triangular in shape, a common characteristic of most vipers. When in danger, the snake powerfully exhales, creating a loud hissing sound.
Rhinoceros vipers are extremely rare and are only found in a few places in the rainforests of western Rwanda, such as Nyungwe Forest. They are usually camouflaged in the leaf litter.
Rhinoceros vipers are typically ambush predators that feed on a wide variety of prey, including birds, mammals, lizards, fellow snakes, and frogs.
5. Forest cobra
The forest cobra, also known as the black cobra or black and white-lipped cobra, is a large and highly venomous snake found in Rwanda. It has a very strong neurotoxic venom similar to but not as strong as that of the black mamba.
Whereas black mamba venom may kill you within four to five hours, the effects of forest cobra venom can last for 12 hours or more.
Bites from the forest cobra are rare because the snakes are 'very shy' and tend to hide or move away when they cross roads with humans. The snakes are common near water sources such as Lake Muhazi or Lake Kivu. They are very good swimmers and enjoy spending time inside the water.
These types of snakes feed on a wide range of prey including fish, frogs, birds and their eggs, rodents, lizards and other water bodies.
6. Gaboon viper
Gaboon vipers are heavily coloured and patterned, with a variety of brown, white and purple colours. They grow impressively large.
Their heads are triangular in shape, powerfully exhale and create a loud hissing when in danger. They are considered extinct in Rwanda.
The last sightings of Gaboon vipers were near the foot of Muhabura in the 1930s. These snakes are highly vulnerable and typically die when their forest habitat is destroyed.
These snakes are believed to have the longest fangs in the world measuring about 3.5 centimetres long. They also have the biggest stock of venom compared to most snakes in the universe.
If bitten by a Gaboon viper, it's usually not the venom itself that kills, but rather a condition called anaphylaxis where the body can no longer handle the amount of foreign toxic substances and simply shuts down.
Apart from the venomous snakes, there are five non-venomous snakes at the Kandt House Museum. The species include the Dasypeltis atra, also known as the egg eater, the Angola bush snake, the Python, the brown house snake and the spotted bush snake.
