The Senegalese cobra (Naja senegalensis) is a species of cobra in the genus Naja that is found in West Africa.
This species was long thought to be identical to the Egyptian cobra (Naja haje), but morphological and genetic differences have led to its recognition as a separate species. [2] It differs from Naja haje in normally having more than 23 dorsal scale rows around the neck and a uniformly dark head without any obvious pattern on the supralabial scales. This species does not spit venom.
Adults are uniformly dark grey-brown dorsally, with slightly lighter lower flanks. The throat is also dark brown with occasional lighter individual ventral scales, whereas the rest of the ventral side is cream with dark grey-brown mottling. The head is dark grey-brown. Juveniles are grey with a black head and neck, and often carry a light blotch on the back of the hood. This normally disappears in adults, although a few specimens retain this marking into adulthood. Size: a large, robust cobra, maximum recorded total length 245 cm. [2]
When confronted by an enemy, this snake will rear up its frontal body and spread out a hood, it might also hiss loudly and charge against the enemy to scare it away. It will only bite as a last resort.
West Africa: documented from Senegal, Guinea, Mali, Burkina Faso, Ghana, Benin, Niger and Nigeria. [2]
The venom of this species is rich in long chain αlpha-neurotoxins. The intravenous injection murine LD50 is 0.39 mg/kg. [3]

Naja is a genus of venomous elapid snakes commonly known as cobras. Members of the genus Naja are the most widespread and the most widely recognized as "true" cobras. Various species occur in regions throughout Africa, Southwest Asia, South Asia, and Southeast Asia. Several other elapid species are also called "cobras", such as the king cobra and the rinkhals, but neither is a true cobra, in that they do not belong to the genus Naja, but instead each belong to monotypic genera Hemachatus and Ophiophagus.
The Mozambique spitting cobra is a highly venomous species of spitting cobra native to Africa. It is largely found in Angola, Botswana, Malawi, Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe.
The Chinese cobra, also called the Taiwan cobra, is a species of cobra in the family Elapidae, found mostly in southern China and a couple of neighboring nations and islands. It is one of the most prevalent venomous snakes in China, which has caused many snakebite incidents to humans.
The rinkhals, also known as the ringhals or ring-necked spitting cobra, is a species of venomous snake in the family Elapidae. The species is found in parts of southern Africa. It is not a true cobra in that it does not belong to the genus Naja, but instead belongs to the monotypic genus Hemachatus. While rinkhals bear a great resemblance to true cobras they also possess some remarkable differences from these, resulting in their placement outside the genus Naja. In 2023, the Zimbabwe population was described as a new species, H. nyangensis.
The red spitting cobra is a species of spitting cobra native to Africa.
The Egyptian cobra is one of the most venomous species of snakes in North Africa, and has caused many snakebite incidents to humans. It averages roughly 1.4 metres (4.6 ft), with the longest recorded specimen measuring 2.59 metres (8.5 ft).

The black-necked spitting cobra is a species of spitting cobra found mostly in sub-Saharan Africa. They are moderately sized snakes that can grow to a length of 1.2 to 2.2 m in length. Their coloration and markings can vary considerably. They prey primarily on small rodents. They possess medically significant venom, although the mortality rate for untreated bites on humans is relatively low. Like other spitting cobras, they can eject venom from their fangs when threatened. The neurotoxic venom irritates the skin, causing blisters and inflammation, and can cause permanent blindness if the venom makes contact with the eyes and is not washed off.
