Etymology

The specific name, goldii, is in honor of George Taubman Goldie, a Manx administrator in Nigeria.[2]

Description

Pseudohaje goldii is one of the largest venomous snakes in Africa, measuring 2.2–2.7 metres (7.2–8.9 ft) in total length (including tail). The dorsal body color of this species is glossy black. It has a cylindrical body with a long, spiky tail, which makes the snake more adaptable to arboreal life. The head is small with exceptionally large eyes, giving the snake excellent eyesight. There are usually 15 rows of dorsal scales at midbody, though there are rare specimens that have 17 rows.

Distribution and habitat

Pseudohaje goldii can be found in Central and Western equatorial African countries, including Democratic Republic of the Congo, Republic of Congo, Gabon, Ghana, Cameroon, and Central African Republic. P. goldii inhabits forests and woodlands along rivers and streams. Being an arboreal species, it is seldom found in open land.

Behavior

Despite its large size, P. goldii is a highly agile snake. It is equally comfortable in trees, on ground and in water. It can move quickly and gracefully through trees with the aid of its spiky tail. It is also a very secretive snake which is rarely seen by people. However, it is one of the few snakes that are considered aggressive. When threatened, it rears up and spreads a typical cobra hood, though its hood is much narrower than that of Naja naja. If it is further provoked, the snake may attempt to bite. Though it cannot spit its venom, its bite is very potent and potentially lethal. It is reputedly ill-tempered. It may also use its tail spike to defend itself if restrained.

Venom

Pseudohaje goldii venom is one of the most toxic and deadly of all African snakes. Venom of this species is primarily a neurotoxin, like most Elapidae. It is quick acting and extremely potent, easily killing a person. Moreover, there is no known specific antivenom made. Bite symptoms include swelling and stinging pain around the bite wound, numbness of limbs and lip, severe difficulty in breathing, sweating profusely and blurred vision. Victims may die of respiratory failure. A number of people are killed by this species.

Diet

Pseudohaje goldii mainly preys on amphibians and arboreal mammals, such as squirrels. It is also known to take fish occasionally.

Reproduction

Pseudohaje goldii is oviparous. The female will lay 10 to 20 eggs.
