Top 10 Most Dangerous Snakes in Nigeria
In this section, we’ll explore each of Nigeria’s most dangerous snakes, highlighting their unique characteristics, habitats, and the reasons they’re considered a threat. Each description will give you insights into their appearance, venom, behavior, and tips for identification. Let’s dive into the list:
1. Saw-Scaled Viper (Echis ocellatus)
The saw-scaled viper is relatively small, usually between 30–60 cm long. It has a distinctive pattern of light and dark bands across its body, which helps it blend into dry, rocky environments. Commonly found in savannahs and arid regions, especially in northern Nigeria. This snake thrives in dry, sandy, or rocky areas.
Known for its highly toxic venom, the saw-scaled viper’s bite can lead to rapid blood clotting and organ failure. It is responsible for a significant percentage of snakebite fatalities in Nigeria. This snake is quick to defend itself and often makes a hissing noise by rubbing its scales together before striking, making it easily recognizable.
2. West African Carpet Viper (Echis leucogaster)
A small to medium-sized snake with a patterned body that includes bands or blotches, aiding in its camouflage. The carpet viper is frequently found in savannah and desert regions, especially in areas with sparse vegetation.
This snake’s venom is hemotoxic, causing intense bleeding, pain, and potentially deadly complications. Known for its defensive behavior, the carpet viper often strikes quickly when disturbed.
3. Puff Adder (Bitis arietans)
A thick-bodied snake, usually 1 to 1.5 meters in length, with a distinctive diamond-shaped pattern on its back. Thw puff adder is widespread across various habitats in Nigeria, from savannahs to farmlands and even near human settlements.
The puff adder’s venom contains cytotoxins that cause extensive tissue damage, pain, and can be fatal if untreated. This snake is slow-moving but will strike rapidly if threatened. Known for “puffing up” its body as a warning, hence the name.
4. Black-Necked Spitting Cobra (Naja nigricollis)
Typically dark gray or black with a lighter underbelly and a distinct black neck that it expands when threatened. The Spitting Cobra is commonly found in savannahs, open woodlands, and farmlands.
This cobra’s venom is both neurotoxic and cytotoxic, causing paralysis, tissue damage, and blindness if it spits venom into the eyes. Unlike other snakes, it can spit venom accurately up to 2 meters as a defensive mechanism. It prefers to avoid confrontation but will defend itself if necessary.
5. Forest Cobra (Naja melanoleuca)
A large snake, often reaching 2–3 meters in length, with a shiny black or dark brown body and a hood. The forest cobra is usually found in tropical forests but can sometimes be spotted near human dwellings.
This cobra’s venom is highly neurotoxic, which can cause respiratory paralysis and death. Known to be one of the most aggressive cobras, the forest cobra will stand its ground and is quick to strike when threatened.
6. Green Mamba (Dendroaspis viridis)
A slender snake with a striking green color, often blending in well with foliage. The Green Mamba is primarily arboreal, living in trees and bushes in forested areas of southern Nigeria. Its venom is neurotoxic, affecting the nervous system and causing rapid symptoms that can be fatal if untreated.
The green mamba is generally shy but will become aggressive if it feels cornered. Its ability to blend in makes it difficult to spot.
7. Gaboon Viper (Bitis gabonica)
A robust, heavy-bodied snake with intricate, leaf-like patterns in shades of brown, purple, and yellow. They are found in rainforests and wooded areas, typically in the southern parts of Nigeria. Known for having the longest fangs of any snake and potent venom that can cause rapid death.
Although slow-moving and generally passive, it can deliver a devastating bite if provoked.
8. Egyptian Cobra (Naja haje)
Characterized by a brownish color with a wide hood, it can reach lengths of up to 2 meters. The Egyptian cobra is typically found in savannahs, deserts, and occasionally near agricultural areas. Contains neurotoxic venom that can lead to respiratory failure and death.
Known for its defensive display, the Egyptian cobra prefers to flee but will defend itself if it feels cornered.
9. Jameson’s Mamba (Dendroaspis jamesoni)
A slim, green snake similar to the green mamba but usually longer, reaching up to 2.7 meters. Jameson’s Mamba is primarily arboreal, found in forested areas and sometimes in urban settings. They have a neurotoxic venom that can cause rapid paralysis and death.
Known for its speed and agility, Jameson’s mamba will strike if threatened but generally avoids humans.
10. Boomslang (Dispholidus typus)
A slender, green snake with large eyes, often well-camouflaged in trees. They are primarily found in forests and woodland areas, usually in trees or shrubs. They have a potent hemotoxic venom that disrupts blood clotting, causing internal bleeding. Fatalities have been reported without quick treatment.
Generally shy and avoids humans but will defend itself if cornered.
Snakebite Prevention Tips
Knowing about these dangerous snakes is helpful, but avoiding a bite is the best way to stay safe. Here are some practical tips for minimizing the risk of snakebites, whether you’re exploring nature, working in the fields, or living in snake-prone areas.
1. Be Cautious in Snake Habitats
Avoid areas where snakes are likely to be present, especially tall grasses, woodpiles, and rocks.Be cautious near water sources, as snakes often go there to drink or hunt.
2. Wear Protective Clothing
Wear boots, thick socks, and long pants if you’re venturing into tall grass, forests, or rocky areas. These offer some protection against potential bites.
3. Avoid Walking in the Dark
Snakes are active at night, especially in warm regions like Nigeria. Use a flashlight if you need to walk in the dark, particularly in snake-prone areas.
4. Watch Where You Step and Sit
Always check your surroundings before sitting on logs, rocks, or grassy areas. Similarly, watch your step and avoid putting your hands in places you can’t see.
5. Don’t Disturb Snakes
If you spot a snake, keep your distance. Many bites occur when people try to handle or move a snake. Simply walk away and allow it to move on.
6. Be Careful Around Storage Areas
Check woodpiles, sheds, and storage areas before reaching into them. Snakes sometimes take refuge in these places, especially during cooler times of the day.
7. Avoid Excessive Perfumes or Strong Smells
Some experts believe strong scents may attract or alert snakes. While not conclusive, it’s generally best to avoid heavily scented products if you’re entering snake habitats.
8. Educate Children and Visitors
Make sure children and guests know about local snake dangers and understand how to act responsibly around them.
By following these preventive measures, you can significantly reduce the risk of a dangerous encounter with a snake. In the next section, we’ll cover essential first aid steps to take if a snakebite occurs. Let me know if you’d like to proceed!
First Aid Tips for Snakebites
Despite careful precautions, snakebites can still occur. Knowing the correct first aid steps can make a crucial difference in minimizing the severity of the bite and increasing the chances of a full recovery. Here’s what to do if you or someone else is bitten by a snake:
1. Stay Calm and Immobilize the Affected Limb
Anxiety and rapid movements can increase blood flow, causing venom to spread more quickly. Keep the affected limb as still as possible, ideally below heart level. Use a splint or any rigid object to prevent unnecessary movement.
2. Remove Tight Clothing or Jewelry
Snakebites can cause swelling, so it’s important to remove any rings, bracelets, or tight clothing from the affected area as soon as possible to prevent restricted blood flow.
3. Clean the Bite Area
Gently rinse the bite area with clean water if possible, but avoid scrubbing or applying any kind of disinfectant, as this could aggravate the tissue.
4. Do Not Use a Tourniquet or Attempt to Suck Out Venom
Using a tourniquet or cutting the bite area can worsen tissue damage and lead to other complications. Avoid trying to suck out venom or using any “snakebite kits” as these methods are not effective.
5. Keep the Person Hydrated and Reassured
Keep the individual calm and hydrated, if possible, to prevent dehydration or shock. Reassuring them can help reduce panic, which in turn helps slow the spread of venom.
6. Seek Medical Attention Immediately
Transport the person to a medical facility as quickly as possible. Make sure to inform medical staff about the bite, the type of snake (if known), and the time of the bite.
7. Avoid Consuming Alcohol or Caffeine
These substances can speed up the absorption of venom and worsen the effects. Stick to water or electrolyte drinks if necessary.
