Snakes of Victoria series

Identification

The Red-bellied Black Snake, Pseudechis porphyiacus, is a shiny blue-black snake, usually with pink colouring on the lower rows of scales. It has 17 rows of mid-body scales, a divided anal scale and 40–65 subcaudal scales, with single anterior and divided posterior scales. It is a large snake: adults can reach over 2 m.

Distribution and habitat

It is widespread in eastern Victoria; north of the Dividing Range it is often associated with water courses. It is also relatively common in Melbourne’s east and has been recorded around Bacchus Marsh, Park Orchards, Bayswater, along the Plenty River in the South Morang area and around the Merri Creek in the Campbellfield to Somerton area.

Biology and bite

This snake is active both day and night, and its diet consists primarily of frogs. Females can produce in excess of 16 live young.

Although the venom is not as potent as that of other venomous land snakes, this species is still dangerous. If bitten on a limb, apply a pressure bandage, immobilise the limb and seek medical advice immediately. If bitten elsewhere, apply continuous direct pressure to the bite site. Do not wash the wound, as the venom on the skin can be used to identify the appropriate antivenom.

This species is quite common proximal to the Yarra river in Melbourne's outer east.

Hi there, We were bushwalking at Cape Otway National Park, heading to Station Beach and came across unfortunately a dead black snake. It was only small but I am curious as to which species this could have been. It did not have a red belly nor a yellow. It was black all over... Hoping you can help me with my query. Many thanks, Michelle :)

Hi Michelle,

The Curator of Herpetology would need to see an image of the specimen to be able to undertake an identification. The snake you saw might have been a juvenile and so an image is needed to be confident in providing a species name. If you have an image please feel free to send it to discoverycentre@museum.vic.gov.au Alternately this link is to the Museum's Bioinformatics website and has images of all snake species found inVictoria.

Hi Micah - You might like to try the Australian Venom Research Unit's site on the Red-bellied Black Snake, or there are links to more images on our Bioinformatics site. Enjoy your walk and don't forget to wear good shoes!

We had a juvenile red bellied black snake, approx. .5 metre long, moving along our fence line in suburban Rowville this morning. There is a wetland area area within 200 metres of our house. We have lived here for 16 years, and this is our first sighting.

While walking on the tarmac path to 'London Bridge' on Vic south coast we saw what might have been a juvenile red bellied......about 18cm long, 5mm wide, jet black with bright red underside. It was sunning itself on the tar! Early April 2011

Hi Sam - you can find out about the snake species in your area using the Museum's Victorian Snakes Bioinformatics page here. We are a little stumped on the other part of your question, apart from advising standing well clear of the car once you pull over if you suspect the snake to be still alive; although we don't really have expertise on this sort of scenario.

One of these had been run over by a car and was dead on the side of the road in the Main Street of Seaspray, a coastal town on the ninety mile beach. It was long, prob 1.5 m. It may have come down from the sand dunes.

Hi ! Awesome! Me and a group of mates fish the surf up there! We always discussed what sorts of snakes frequent the 90 mile coast! All that area is surrounded by large lakes!

I saw a red bellied black snake at Rainbow in Victoria's Mallee. I was amazed at just how red its belly was. It was probably close to 2 metres in length.
