Species description
Geographical Origin and Habitat: Echis hughesi is a highly specialized viper species endemic to the semi-arid, rocky regions of northern Somalia in the Horn of Africa. It inhabits harsh, dry environments such as rocky hillsides, limestone canyons, and dry riverbeds (wadis) where sparse, thorny scrub vegetation is the only plant cover. The species has evolved to withstand extreme drought, seeking refuge under flat rocks, deep crevices, and abandoned rodent burrows to protect itself from the scorching daytime heat.
Taxonomy and Genetics: First described scientifically in 1990 by the herpetologist Cherlin, this species belongs to the family Viperidae, subfamily Viperinae, and the genus Echis. Genetically, it belongs to the Echis carinatus species complex but is distinguished by unique meristic counts, specifically the number of ventral and subcaudal scales, and distinct head scale arrangements. Molecular studies support its status as a distinct evolutionary lineage shaped by geographic isolation.
Behavior and Habits: Primarily nocturnal and crepuscular, adapting its activity patterns to avoid the intense heat of the Somali sun. When threatened, it displays a classic warning behavior known as stridulation: it loops its body into C-shaped coils and rubs its serrated lateral scales together, producing a loud, sizzling sound that resembles boiling water. It is a highly nervous, fast-striking snake that will not hesitate to bite if provoked. It moves using sidewinding locomotion.
Morphology: This is a small viper, with adult specimens reaching an average total length of only 28 to 32 centimeters. The body is relatively stout, with a short tail and a distinct, wedge-shaped head covered in small scales and clearly separated from the neck. The eyes are moderately large with vertically elliptical pupils. Coloration consists of a greyish-brown background marked with a series of whitish, dark-bordered saddles along the back, while the venter is white.
Care, breeding and tankmates
Terrarium Setup: Must be housed individually in a secure, escape-proof desert terrarium measuring at least 60x40x40 cm. The substrate should consist of a dry mixture of fine play sand, fine gravel, and crushed clay to a depth of 4-5 cm. It is critical to provide stable, secure rock shelters and cork bark hides in both the warm and cool zones to allow for stress-free thermoregulation. Climbing branches can be added but are not strictly necessary.
Lighting and Heating: A sharp temperature gradient is required during the day: the cool end of the enclosure should be maintained at 24-26°C (75-79°F) at the warm end at 32-34°C (90-93°F), with a focused basking spot reaching 36-38°C (97-100°F). At night, all heating sources should be turned off to allow a drop to 20-22°C (68-72°F). High-quality 5.0 UVB lighting is recommended to facilitate vitamin D3 synthesis and natural behavior.
Humidity and Hydration: Relative humidity must be kept low, between 30% and 40%. Elevated humidity levels will lead to scale rot and fatal respiratory infections. A small, shallow water dish should be provided at the cool end of the terrarium and cleaned daily. During shedding cycles, a temporary humid hide containing damp sphagnum moss can be introduced to prevent retained sheds.
Feeding and Supplementation: In captivity, they feed on small rodents such as pinky mice. Food should be offered pre-killed and defrosted, and must only be presented using long feeding tongs for safety. Adult vipers should be fed once every 10 to 14 days. Preys should be dusted with calcium and vitamin D3 supplements once a month. Avoid overfeeding, as their metabolism is extremely low.
Compatibility: Strictly solitary. Do not house multiple specimens together, as this causes severe stress and carries a high risk of cannibalism. Because this species is highly venomous and dangerous, it must never be handled directly. All tank maintenance and animal transfers must be conducted using professional snake hooks, feeding tongs, and secure shift boxes.
Health and Common Diseases: Vulnerable to metabolic bone disease if UVB and calcium are lacking, and scale rot if the substrate becomes damp or dirty. Constipation can occur if the snake is dehydrated. Bite incidents are medical emergencies requiring immediate antivenom administration. Weekly spot cleaning and monthly deep cleaning with reptile-safe disinfectants are mandatory to prevent pathogen buildup.

The catalog's scalar value is 85 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 85 cm for this species, recorded as total length (TL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
