The rufous beaked snake (Rhamphiophis oxyrhynchus) is a species of mildly venomous snake in the family Psammophiidae. The species is native to East Africa. Its common name refers to its hooked snout, which it uses to dig burrows, and to its reddish-brown dorsal coloration. It hunts small animals during the day with the help of its venomous bite. [3] [4]

Taxonomy

The two subspecies are R.o. oxyrhynchus(J.T. Reinhardt, 1843) and R.o. rostratus W. Peters, 1854. [1] Some authorities consider the latter to be a species, R. rostratusW. Peters, 1854. [5]

Description

The rufous beaked snake is large and stout, with males reaching a maximum length of 1.1 m (3.6 ft) and females reaching 1.07 m (3.5 ft). It has a shortened skull, as with all beaked snakes, giving it a clear distinction between its head and body, as well as a dark brown eye stripe running down the side of its head. [6] Its eyes are large with round pupils. Its back ranges from grey to yellowish-brown to reddish-brown, and its belly is cream or yellowish-white. [7]

Geographic range

The rufous beaked snake's range includes north Botswana, north Zimbabwe, Mozambique, Tanzania, Uganda, Kenya, South Sudan, and Sudan,

Habitat

It primarily inhabits bushveld and thornveld (bushland) habitats. [7]

Biology

Diurnal animals, rufous beaked snakes hunt small animals, including other snakes, but stay in burrows during the hottest part of the day. In the summer, females lay eight to 17 cylindrical eggs with dimensions of about 36 mm × 21 mm (1.42 in × 0.83 in) over the span of several days. [7] The snake's venom, one of its components of which is a neurotoxin called rufoxin, causes hypotension and circulatory shock in small mammals, but is not dangerous to humans. [4] [8]

Cerastes cerastes, commonly known as the Saharan horned viper or the desert horned viper, is a venomous species of viper native to the deserts of Northern Africa and parts of the Arabian Peninsula and Levant. It is often easily recognized by the presence of a pair of supraocular "horns", although hornless individuals do occur. Three subspecies have been described.

It is the largest member of the genus Bitis, and has the longest fangs of any venomous snake – up to 2 inches (5 cm) in length – and the highest venom yield of any snake. No subspecies are recognized.

<span class="mw-page-title-main">Inland taipan</span> Highly venomous snake native to Australia

The inland taipan, also commonly known as the western taipan, small-scaled snake, or fierce snake, is a species of extremely venomous snake in the family Elapidae. The species is endemic to semiarid regions of central east Australia. Aboriginal Australians living in those regions named the snake dandarabilla. It was formally described by Frederick McCoy in 1879 and then by William John Macleay in 1882, but for the next 90 years, it was a mystery to the scientific community; no further specimens were found, and virtually nothing was added to the knowledge of this species until its rediscovery in 1972.

<span class="mw-page-title-main">Eastern brown snake</span> Highly venomous snake native to Australia

The eastern brown snake, often referred to as the common brown snake, is a species of extremely venomous snake in the family Elapidae. The species is native to eastern and central Australia and southern New Guinea. It was first described by André Marie Constant Duméril, Gabriel Bibron, and Auguste Duméril in 1854. The adult eastern brown snake has a slender build and can grow to 2 m (7 ft) in length. The colour of its surface ranges from pale brown to black, while its underside is pale cream-yellow, often with orange or grey splotches. The eastern brown snake is found in most habitats except dense forests, often in farmland and on the outskirts of urban areas, as such places are populated by its main prey, the house mouse. The species is oviparous. The International Union for Conservation of Nature classifies the snake as a least-concern species, though its status in New Guinea is unclear.

<span class="mw-page-title-main">Red-bellied black snake</span> Venomous snake native to eastern Australia

The red-bellied black snake is a species of venomous snake in the family Elapidae, indigenous to Australia. Originally described by George Shaw in 1794 as a species new to science, it is one of eastern Australia's most commonly encountered snakes. Averaging around 1.25 m in length, it has glossy black upperparts, bright red or orange flanks, and a pink or dull red belly. It is not aggressive and generally retreats from human encounters, but can attack if provoked. Although its venom can cause significant illness, no deaths have been recorded from its bite, which is less venomous than other Australian elapid snakes. The venom contains neurotoxins, myotoxins, and coagulants and has haemolytic properties. Victims can also lose their sense of smell.

<span class="mw-page-title-main">Black mamba</span> Species of venomous snake

The black mamba is a species of highly venomous snake belonging to the family Elapidae. It is native to parts of sub-Saharan Africa. First formally described by Albert Günther in 1864, it is the second-longest venomous snake after the king cobra; mature specimens generally exceed 2 m and commonly grow to 3 m (9.8 ft). Specimens of 4.3 to 4.5 m have been reported. Its skin colour varies from grey to dark brown. Juvenile black mambas tend to be paler than adults and darken with age. Despite the common name, the skin of a black mamba is not black, but rather describes the inside of its mouth, which it displays when feeling threatened.

<span class="mw-page-title-main">Toxicofera</span> Proposed clade of scaled reptiles

Toxicofera is a proposed clade of scaled reptiles (squamates) that includes the Serpentes (snakes), Anguimorpha and Iguania. Toxicofera contains about 4,600 species, of extant Squamata. It encompasses all venomous reptile species, as well as numerous related non-venomous species. There is little morphological evidence to support this grouping; however, it has been recovered by all molecular analyses as of 2012.

<i>Hydrophis belcheri</i> Species of snake

Hydrophis belcheri, commonly known as the faint-banded sea snake or Belcher's sea snake, is an extremely venomous species of elapid sea snake. It has a timid temperament and would normally have to be subjected to severe mistreatment before biting. Usually those bitten are fishermen handling nets, although only one-quarter of those bitten are envenomated since the snake rarely injects much of its venom. Although not much is known about the venom of this species, its LD50 toxicity in mice has been determined to be 0.24 mg/kg when delivered intramuscularly.

<span class="mw-page-title-main">Venomous snake</span> Species of the suborder Serpentes that produce venom

Venomous snakes are species of the suborder Serpentes that are capable of producing venom, which they use for killing prey, for defense, and to assist with digestion of their prey. The venom is typically delivered by injection using hollow or grooved fangs, although some venomous snakes lack well-developed fangs. Common venomous snakes include the families Elapidae, Viperidae, Atractaspididae, and some of the Colubridae. The toxicity of venom is mainly indicated by murine LD50, while multiple factors are considered to judge the potential danger to humans. Other important factors for risk assessment include the likelihood that a snake will bite, the quantity of venom delivered with the bite, the efficiency of the delivery mechanism, and the location of a bite on the body of the victim. Snake venom may have both neurotoxic and hemotoxic properties. There are about 600 venomous snake species in the world.

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 described as a new species, H. nyangensis.

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.
