Black Mamba
Dendroaspis polylepis • Order: Squamata, Suborder: Serpentes, Family: Elapidae, Subfamily: Elapinae, Genus: Dendroaspis, Species: Dendroaspis polylepis
Venomous Status
Highly Venomous - Proteroglyphous (fixed front fangs)
Danger Level
Extremely Dangerous - One of the most feared snakes in Africa due to high toxicity, speed, and potential for multiple strikes. Without antivenom, mortality is nearly 100%.
Geographic Range
Sub-Saharan Africa, including regions of East, South, and Central Africa. Countries include (but not limited to) South Africa, Kenya, Tanzania, Botswana, Zimbabwe, and Ethiopia.
Conservation Status
Least Concern (IUCN Red List). However, habitat loss and persecution by humans remain localized threats.
Physical Description
Despite the name, the body is usually olive, brownish-grey, or khaki. The 'black' refers to the ink-black coloration inside its mouth. It has a coffin-shaped head, large dark eyes, and smooth scales.
Size & Dimensions
Typically 2.0 to 3.0 meters (6.6 to 9.8 ft), but can reach up to 4.5 meters (14.8 ft). The specimen in the image appears to be a sub-adult or adult based on body thickness.
Habitat
Savannas, rocky hillsides, and open woodlands. Often found in termite mounds, hollow logs, or rock crevices. Occurs from sea level up to 1,800 meters elevation.
Behavior & Temperament
Highly alert and nervous. While shy and preferring to flee from threats, it is extremely defensive if cornered. Known for its 'gaping' display (showing the black mouth) and its ability to move at speeds up to 11 km/h.
Diet & Feeding
Diurnal active forager. Feeds primarily on small mammals (rodents, squirrels, hyraxes) and occasionally birds. Uses a 'strike and release' strategy for small prey or maintains a grip until venom takes effect.
Reproduction
Oviparous. Females lay clutches of 6 to 17 eggs in early summer. The young are independent upon hatching and are immediately venomous.
Venom & Safety
Venom Type
Potent neurotoxins (dendrotoxins) and cardiotoxins. Rapidly affects the nervous and respiratory systems, leading to muscle paralysis and respiratory failure.
First Aid Advice
Immediate medical emergency. Use a Pressure Immobilization Bandage (PIB) on the limb, keep the patient still, and transport to a hospital with polyvalent antivenom (SAIMR) immediately. Mechanical ventilation is often required.
Look-alikes
Often confused with Green Mambas (Dendroaspis angusticeps) when young, or various Cobras (Naja spp.). It is distinguished by its uniform matte grey/brown color and specific head shape.
Conservation Status
Least Concern (IUCN Red List). However, habitat loss and persecution by humans remain localized threats.
Cultural Significance
A major icon in African folklore and modern media (e.g., 'Kill Bill'). Plays a vital ecological role in regulating rodent populations in savanna ecosystems.
Notable Features
Fastest land snake in Africa; the 'coffin-shaped' head and jet-black interior of the mouth are diagnostic. It is one of the few snakes that can lift its body significantly off the ground to strike at chest height.
