Sunbeam Snake

Looks how to spot one

scales

The body is cylindrical and streamlined with a wedge-shaped head that blends into the neck, perfect for burrowing. The scales are exceptionally smooth, polished and iridescent, giving a glossy purple-blue sheen when light catches them. The belly is unpatterned whitish-grey.16

Personality what they are like

Sunbeam snakes are shy and secretive by nature. They are not venomous and are generally docile, but they stress very easily. If handled roughly they may bite, though they prefer to escape. When threatened they may vibrate their tail like a rattlesnake and release a very strong, unpleasant musk. They are best left alone and handled only when absolutely necessary.174

Daily activity how busy a day looks

Nocturnal and fossorial. They spend most of their time hidden underground and emerge at dusk to hunt. They do not need large spaces to roam, but they must have deep substrate to burrow in.17

Grooming and care the hands-on bits

Very low grooming needs. The main care requirements are maintaining high humidity (80-100%), providing a deep moist burrowing substrate such as cypress mulch or sphagnum moss, and keeping temperatures between 24-30°C (75-88°F) with a warm and cool end. A shallow water dish should always be available. They are not suitable for beginners due to their specific needs and stress sensitivity.764

Home where they are happiest

A 40-gallon tank is sufficient for one or two snakes. The enclosure must have a deep layer (15-20 cm) of moist substrate like cypress mulch or moss for burrowing. Humidity should be kept very high (80-100%). A temperature gradient of 24-26°C (75-80°F) on the cool side and 28-30°C (86-88°F) on the warm side is ideal. Provide a hide and a shallow water dish. They are not venomous and are legal to keep in most countries, but check local regulations.764

Food basics what goes in the bowl

Carnivorous. In the wild they eat frogs, reptiles (including other snakes), and small mammals. In captivity they readily accept pre-killed or stunned rodents such as mice. They are constrictors and feed very quickly.17

Company who they like around

Solitary and secretive. They do not need company and can be housed alone. Handling should be kept to a minimum to avoid stress. They are not a pet for young children or inexperienced keepers.74

The story where it all began

The sunbeam snake has been known to science since the early 19th century, first described by Reinwardt in 1827. It is the only species in the family Xenopeltidae. In the pet trade, most individuals are wild-caught and imported, as captive breeding is rare. Unfortunately, many imported snakes die within the first six months due to stress and improper care. However, those that survive can adapt well. The first detailed account of successful captive breeding in a zoo was published in 1997, covering a six-year period at Chester Zoo in the UK. Their stunning iridescent scales make them popular, but their delicate nature means they are best suited to experienced keepers.671
