Blue-bellied Black Snake: Pseudechis guttatus

The Blue-bellied Black Snake, Pseudechis guttatus, is a venomous Australian elapid also known as the Spotted Black Snake. [1] [2] WildGuardian’s HIGH label reflects the potential medical danger of a bite. It is not an invitation to assess the animal closely: keep clear of every snake and treat a suspected bite as an emergency.

The Australian Museum describes the species as usually shy, but capable of a strong defensive response when threatened. [1] A snake that appears still, small or familiar can still bite if handled, cornered or surprised. The safest encounter is a distant one that leaves the animal an escape route.

Identification: observations, not a handling test

Many Blue-bellied Black Snakes are shiny bluish- or brownish-black above, with a dark bluish-grey or black belly. The body is robust, the head is broad and deep, and it is only slightly distinct from the neck. Some animals have pale grey or cream scales edged in black, creating a spotted appearance; others may show thin broken crossbands. In all of these forms, the head is uniformly dark. [1]

These are useful background clues, not a way to decide that an unknown snake is safe. The Australian Museum notes potential confusion with Red-bellied Black Snakes and Eastern Brown Snakes, among others. [1] Colour, location and apparent behaviour cannot replace distance. Do not move closer, lift debris, touch the animal or try to obtain a better photograph.

Range, habitat and behaviour

This species occurs just west of the coastal ranges in south-east Queensland and north-east New South Wales. [1] [2] It uses a broad mix of country, including river floodplains, wetlands and riparian areas, as well as dry sclerophyll forest and woodland. Likely shelter includes fallen logs, dense vegetation, deep soil cracks and abandoned animal burrows. [1]

It is mainly a terrestrial, daytime hunter of frogs, lizards, snakes and mammals, though it may forage on warm evenings. [1] That ecology helps explain why it can be encountered near water or in forest and woodland, but does not predict an animal’s presence at a particular site or time.

When pressured, it may hiss, flatten its forebody into a low S-shape and strike. [1] This is defensive behaviour. Back away calmly, keep pets and children away and do not block the snake’s path. If it is in a place where safe separation is impossible, contact an appropriately licensed local snake-removal service rather than trying to move it yourself.

Suspected bite: emergency response

Every suspected Australian snake bite should be treated as potentially life-threatening. Healthdirect directs people to call 000 for an ambulance, or try 112 from a mobile if triple zero does not work. [3] Do not wait for symptoms or species confirmation.

Keep the person still and calm. Apply pressure immobilisation: put a roller bandage over the bite, then apply a firm second bandage from the fingers or toes upward over the limb, and splint the limb to limit movement. [3] Keep the bandage on, record the time and stay with the person until paramedics arrive.

Do not wash the bite, cut it, suck it, apply a tourniquet or try to catch or kill the snake. [3] If the person is unresponsive and not breathing normally, start CPR while following emergency-dispatcher instructions.

Frequently asked questions

Is the Blue-bellied Black Snake the same as the Spotted Black Snake?

Yes. Both common names are used for Pseudechis guttatus. [1] [2]

Where might it occur?

Its documented range is in south-east Queensland and north-east New South Wales, in wetland, riparian, forest and woodland settings. [1]

Is a black snake with a blue-grey belly safe to approach?

No. A description is not a safe identification. Similar-looking snakes occur within its range, and the animal may bite defensively if disturbed. [1]

What should I do after a possible bite?

Call 000 immediately, keep the person still, apply pressure immobilisation and do not wash or interfere with the bite site. [3]
