Distribution and habitat

The Small-eyed Snake is widespread in the warm, dry forests of southern and eastern Victoria.

Biology and bite

A secretive, nocturnal species, the Small-eyed Snake preys predominantly on scincid lizards. Females produce up to 7 live young.

Although small it is regarded as dangerous. If bitten on a limb, apply a pressure bandage, immobilise the limb and seek medical advice immediately. If bitten elsewhere, apply continual direct pressure to the bite site. Do not wash the wound as the venom can confirm the identification of the snake.

Thank you for your feedback on our finding of the small-eyed snakes. Makes sense. Choughs are amazing birds to watch - in their social behaviour and in the way they express alarm and communicate with each other. Will post re any further sighting of small-eyed snakes.

[See initial report -Bob & Adrian - above)Found **another** small-eyed snake today on a freezing cold afternoon in exactly the same position as the previous one. I was altered by a group of white-wing choughs being very agitated and noisy and then saw the snake at their feet. Snake was either injured or inhibited by the cold; it writhed and contorted. I was able to pick it up on a plastic lawn rake and return it to the bush. Was it brought there by the choughs? Did the choughs bring it (to in front of the house) the previouys time? But, if so, how do the choughs find a hibernating snake? Perhaps, perhaps the snakes hibernate in deep leaf litter and choughs find them while foraging as they do across the ground in the open bush?

Hi Bob,

White-winged Choughs (Corcorax melanorhamphos) feed on litter-dwelling invertebrates such as insects, worms and snails, as well as seeds. They may encounter snakes during foraging, including hibernating snakes, particularly as they move through the undergrowth in a group, but they are unlikely to feed on them. Choughs, like many birds and other animals, will produce alarm calls and exhibit excitable behaviour when snakes are encountered, which may explain the behaviour you observed.

Sarsfield, 15 km NE of Bairnsdale: Found a (almost certainly) small-eyed snake (approx 40cm)in grass in front of house this morning.Temperature only about 5C. It was lethargic though got somewhat more active as sun shone onto it. Became somewhat aggressive when probed. Very noticeable white tongue.

I found a dead possibly small eyed snake on back path, crushed head and broken spine. All our animals were inside, what could cause these injuries? Early morning in far south coast.

Hello, Does Cryptophis nigrescens have any natural predators? I'd really appreciate any information you might have on the spatial distribution of this species. Thanks!

Hi Shai,

There a number of predators for snakes including butcherbirds, goshawks, harriers, ibises, kites and kookaburras. Snakes are also parasitized for example by various ticks, nematodes and flukes. Humans of course have real impact on the success of their population – both positive and negative.

Hi Phil, thanks for the question.  Unfortunately, the herpetologist is not able to identify the snake from your description along, she would need an image, did you manage to take a photograph?  If so, send it in to us in the Discovery Centre, if not, keep the camera ready for the next time you are out on your property.

Think we had one to day in Langwarrin...we're on 4 acres, Mornington peninsula area. Grey with a yellowish undertinge, timid...slid away quickly under a building, about 750cms long. Is that what it is most likely to be? Definitely grey.

hey snake catchers have got a few callouts for these guys lately as the humid weather is apparently bringing them out. i have seen them on the peninsula once. I was wondering if there were a few spots or spots that u could tell me so i could take photographs of them in the wild. i no a few places one in south east melbourne one to the north east of melbournes suburbs one to the east and one the the west which that population is not so good. Generally there distribution around melbourne is the north east and the east a few spots on the mornington peninsula and a spot out west and a few uncomfirmed records south west

Hi Diana - Melanism (dark/black colouring) is very common in snakes, and this snake can be a dark colour as part of its natural variation. They have small live litters, and this is breeding season, so it is possible you had a juvenile in your window. However, there are many species with small, dark juveniles! Please note, this is a venomous species, and as with all snake encounters, if you are unsure please contact a local snake handler or your local council for assistance.

Small eyed snakes are not only found in Victoria, we got rid of one out of our laundry today, and we are in the Gulf of Carpentaria, QLD.
