Distribution and habitat

The Blotched Blue Tongue is common in the east and north east areas of Melbourne. It is commonly found basking, or sheltering under cover such as fallen logs or discarded rubbish, such as timber or iron.

Biology

Its diet consists of both plant and animal material. It loves to eat snails and slugs which should make it a welcome visitor to our gardens. The females give birth to as many as 12 live young in a litter.

Hi Chris. Several lizard species are native to suburban areas, so there's a chance that you can release this specimen where you found it. Also, if you'd like museum experts to identify the species, you can follow these guidelines for identification requests, and send us a clear photo of the reptile via our online form.

Hi, I just wanted to let you know my Blotched Blue-tongue died today at the age of 26 1/2 years old :(. He was born Easter 1983. He didn't seem ill two days ago and seemed to die suddenly. Thought you might be interested in knowing how long they can live for. I am very sad as I was only 11 when he was born and am now almost 38. He lived in an outdoor enclosure and hibernated every winter. He mostly ate snails, bananas and dog food.

Hi, My husband brought home a blue-tongue lizard that he found curled up in the lunch room. We have a reptile encloser with heating and have fed him snails and grapes which he ate. What I want to know is If we dicide to let him go would it be best to put him back where we found him or is our back yard ok. We are in the country near hanging rock.Also its markings don't seem to match an eastern or southern blotchy skink,is there a web site I can look up all types of blue tongues.(ps) can I put any tree branches and leaves in the encloser.8

Hi Lorrrain, by the sound of it you may need to confirm he is a local species of blue-tongue. There is a possibility that if he is very comfortable in captivity and feeding well already that he may be an accidental escapee, this also correlates with the fact you say he does not look like a local. If you sent in some photos to the Discovery Centre it may throw some light on the issue. If it is a local species the best thing you could do is release him back to his local habitat. Is there adequate habitat for you blue tongue around your husband’s work? The lizard needs a place to hide and enough food to survive

Hey, one of my friends found a female blue tongue in an Industrial Estate, 5 years ago and has kept it ever since as a pet, with another female, which she had for 10 years. Recently it died, and my friend felt terrible keeping one, so she brought it to my house to release, as I live on 72 acres of bushland. However, I didnt think it was going to survivee (we've cared for an injered blue tongue before for a wildlife carer, as it had been mauled by out dog and was not fit to release.). 2 hours after we released her lizard, I went to check it, and despite all the sunlight, she'd moved about 30 cm. I took her home and she was totally dehydrated. I'm trying to relocate her as she does love being outside, however after 5 years I dont think you can just let her go. So I've been keeping her in a guinea pig cage for the last 4 or 5 days, to get her used to the weather, and putting snails in her cage. I've also started putting a little bit of banana in her cage every morning, as I plan to leave her some banana every day for about a month after I release her, to make sure she's getting some food. However, I'm still not sure I'm doing the right thing. Do you have any tips on how to re-locate a blue tongue? I dont want to keep her for too long, I'm scared I'll get attatched. Thanks so much! Josie

Hi Josie - Most animals that have been raised in captivity have to be released into the wild very slowly and carefully – giving them plenty of time to acclimatise to their new environment and learn how to fend for themselves. I can see three main problems with you releasing your blue tongue: 1) It is illegal to either collect animals from the wild without special permission or release captive animals into the wild. 2) You don’t know where this animals ‘genetics’ originated from so you are releasing an animal into a new area where it may not be found naturally, or releasing different genetics into a population. 3) The wellbeing of the animal should be considered and whether this is the best thing for the animal and its chance of survival. 

This may not be the response you are looking for but it would be good if you could consider these points when making your final decision on what to do with your pet.
