There are about 32 species of cobras in the world, many types of cobras are familiar to the public, such as: Zhoushan cobra, Egyptian cobra, Bengal cobra and other highly venomous cobras, all cobras in the world belong to highly venomous snakes, cobras are mainly distributed in Asia and Africa. Water cobras are relatively unfamiliar to most people, but they are far more venomous than the black mamba in Africa.
Water cobras are mainly distributed in the central and western regions of Africa, they like to live in lakes or rivers near dense forests, water cobras belong to a semi-aquatic snake, they do not like most cobras like to live on land, they prefer to live in water, they can stay underwater for more than 10 minutes, because of long-term living in water, their mobility on the road is more seriously degraded, and the action on land is relatively slow.
The main food of other cobras is rodents, birds or frogs, but the food of water cobras is a little different, perhaps because of the semi-aquatic snakes, the food of water cobras is mainly fish in the water or other frogs and toads.
The water cobra is a large venomous snake with an average body length of more than 2.2 meters and a maximum length of more than 2.7 meters. The water cobra is also known as the ring cobra because of the pronounced black rings on its body.
Many people think that the most venomous snake in Africa is the black mamba, which is influenced by relevant documentaries, plus the water cobra belongs to a relatively low-key snake, and there are no daily records that the water cobra has poisoned humans. In 1991, scientists confirmed that the toxicity of the black mamba snake was surpassed by the water cobra and the Zaire water cobra, according to some studies, its toxicity capacity LD50 intravenous injection is 0.2mg/kg, the average amount of poison is 80-250 mg, so a mouthful of venom of a water cobra can easily kill nearly 19,000 mice, which is far stronger than the black mamba, and even the toxicity strength can be comparable to the king cobra.
