Red-bellied Black Snake

🔤 Taxonomy

Pseudechis porphyriacus is the currently accepted scientific name. The historically important combination Coluber porphyriacus still appears in older literature. It is the type species of Pseudechis and the only living-bearing member of the genus.

Identification must use reliable provenance and diagnostic characters rather than colour alone; locality records are especially important where related elapids overlap.

📌 Description

Red-bellied Black Snake is a fast, highly venomous elapid reaching roughly 120-180 cm and requiring a commitment of about 15-20 years. It is an expert-only, display-only animal for a purpose-built venomous facility. A calm captive individual remains capable of life-threatening envenomation.

It is not a spitting cobra, but any bite is an immediate medical emergency; apparent reluctance to strike is never a safety control.

☠️ Venom

This species is venomous. Venom exposure can cause pain, swelling or other systemic effects, and severity varies with species, locality, bite site and the amount delivered. A small wound or apparently dry bite is not proof of safety; every bite or sting requires urgent medical assessment.

If an incident occurs, move away, call emergency services or a poison centre, keep the patient still, remove rings and other constricting items, and follow dispatcher instructions. Do not use a tourniquet, cut or suck the wound, apply ice or electricity, give alcohol or medicines as a home treatment, or attempt to catch the animal. Antivenom choice and dosing are hospital decisions; verify the relevant product and local availability in advance.

🌍 Distribution

The documented native range covers eastern Australia from southeastern Queensland through New South Wales and Victoria to southeastern South Australia. It uses wetlands, creeks, swamps, seasonally flooded grassland and woodland. Country-level shading overstates local occupancy and should not be read as continuous distribution.

⚖️ Legal status

Pseudechis porphyriacus is not currently listed in the CITES Appendices, and no species-specific EU wildlife-trade annex listing was found. No species-specific Bern Convention listing applies. This status was checked against the official CITES, EU and Bern sources on 4 September 2026.

Local and national dangerous-animal, wildlife, import, transport, breeding and sale rules remain separate and may require permits, inspection, insurance or prohibit private possession. Obtain written confirmation before acquisition and retain invoices, breeder details, identification photographs, origin and transfer/import documents.

🤌 Husbandry

House this species singly in a locked venomous-animal room with secondary containment. Connect the enclosure to two full-body shift hides that close and lock externally. Water, waste and removable furniture are serviced only after positive visual confirmation that the snake is secured in the other compartment. Free handling, necking and routine manual restraint are unacceptable.

Quarantine every arrival for at least 90 days on paper with separate tools and preferably separate air. Record weight, feeding, sheds, faeces, skin, mouth and respiration. Animals of uncertain origin need identification review, parasite testing and veterinary assessment before permanent housing.

💡 Lighting

Provide 10-13 hours of broad visible light, complete darkness at night and opaque shaded retreats. Low-level UVB over part of the warm zone may offer Ferguson Zone 2 exposure, but the snake must be able to avoid it completely. Mount or guard every fitting outside reach.

🌡 Heating and temperature

Maintain ambient air at 23-28°C, a local basking surface at 29-31°C, a cool refuge at 20-23°C and nights around 18-22°C. Thermostat every heater independently and verify air and surfaces at snake level.

Seasonal reduction belongs only in a locality-backed programme for healthy established adults. Never cool juveniles, thin animals, new arrivals or snakes with respiratory signs, and always preserve a usable gradient.

💧 Humidity and water

Maintain a ventilated 50-70% baseline and a local humid hide around 70-85% during shedding. Keep most substrate dry enough to prevent dermatitis and stale-air respiratory disease. Provide a heavy clean bowl that can be exchanged through protected access and monitor drinking, urates, mass and shed quality.

🌿 Enclosure and decoration

Use at least 200 x 100 x 100 cm for a typical adult and enlarge for unusually long or active animals. Provide two externally operated shift hides, anchored cover, low shelves or branches, visual barriers and an unobstructed route between shifts. The layout must allow staff to account for the whole animal before any port opens.

Use 8-12 cm of compactable low-dust soil-based substrate, or paper during quarantine. Avoid aromatic wood, sharp or unstable décor, adhesive tape and inaccessible cavities. Guard vents and cable ports, use two independent locks and label the enclosure with taxon, animal count, venom risk and emergency contacts.

🐁 Feeding

Offer appropriately sized frozen-thawed whole rodents, usually every 7-14 days, adjusted to age, body condition, activity and reproductive state. Smaller moderate meals are safer than oversized prey. Whole vertebrate prey needs no routine supplement.

Feed through a protected port and secure the snake before recovering remains. Live prey creates avoidable injuries and unsafe service work. Persistent refusal or regurgitation calls for review of temperature, security, parasites and disease, not repeated handling.

🛡 Operational safety and emergencies

Use protected contact, locked shifts, rigid transparent barriers and task-specific tools. Two trained adults attend every primary opening. Keep current inventory, lock and drill records, species identification, escape equipment and a written bite plan. Before acquisition, agree the receiving hospital, poison-centre advice, transport and antivenom consultation pathway; private antivenom administration is not a medical plan.

Every suspected bite is an immediate emergency: withdraw safely, call emergency services, keep the patient still and follow the pre-agreed professional protocol. Do not cut, suck, ice, shock, apply chemicals or use a tight arterial tourniquet, and never delay transport to catch the snake.

🥚 Breeding notes

This species is viviparous. Females generally produce 5-18 young after a managed seasonal cycle. Breeding greatly increases exposure and requires remote separation, secure individual neonatal boxes, permits and lawful qualified placements before pairing. Never manually examine a gravid female.

🩺 Common problems

Rostral trauma: repeated rubbing suggests reflections, poor cover or unsuitable shift geometry.
Burns and heat stress: guard and thermostat every source while retaining a measured cool refuge.
Respiratory disease: wheeze, bubbles, open-mouth breathing or abnormal posture requires urgent reptile-veterinary assessment.
Dermatitis and dysecdysis: correct saturation, stale air, dehydration and missing textured surfaces without manually restraining the snake.
Parasites and stomatitis: uncertain-origin animals require strict quarantine and diagnostics.
Obesity or regurgitation: review prey size, intervals, heat and disturbance.

📌 Conclusion

Red-bellied Black Snake belongs only in a licensed, escape-contained facility where every routine task can be completed behind a locked barrier. The enclosure, trained team and hospital-coordinated emergency plan must be operational before the animal arrives.
