Is the stripped mash frog poisinous to dog? Also does it live in QLD?
maDIE 12 February, 2011 13:07
i have a frog in my backyard it kinda looks lyk tthiz and is it poisonous can i pick it up?
Discovery Centre 15 February, 2011 12:55
Madie - as it is a wild animal, we don't recommend you try picking up the frog. However, we don't believe Striped Marsh Frogs pose any health concerns to humans
julie 21 February, 2011 13:39
hi, this states up to 75mm so how small could they be? the frog that I had in my living room was around 30mm. would this make it a different striped frog or a recent graduate from tadpole to frog? also Tim hasn't got an answer posted, are they poisonous to large dogs? Lignite barked at it but backed off any time it moved (she also did this for the blue tongue lizard we encountered) but would like to know. thanks Julie

Hi Julie; while it is possible that the frog you saw was a very young adult Striped Marsh Frog, it could equally be another species, you can try identifying it via the Bioinformatics website on frogs at . In terms of toxicty, our resources show the Striped Marsh frog has no known toxins, however you might be better placed checking with a specialist veterinarian to clarify on any problems these animals pose to dogs.

I am growing some Limnodynastes peronii, this frog is not toxic, and to maDIE, The Striped Marsh frog will make a knocking sound. A good site to go to is,

I have two mash frogs in my backyard drains! I can't remove them as most of the time they are in the pipes, what should I do and can I get fined for having then in my garden? I live in Sydney, NSW
Discovery Centre 29 January, 2012 16:28

Hi Ben, there are two types of Marsh Frog - the Striped Marsh Frog (Limnodynastes peroni) and the Spotted Marsh Frog (Limnodynastes tasmaniensis). They look very similar and have similar distributions and life styles, and both occur in Sydney, but your frogs are most likely to be the latter.

Marsh Frogs can be common in suburban areas and many gardeners build frog bogs to encourage them. Having frogs in your backyard can be a sign of a healthy environment, particularly if they've moved in of their own accord. You can't be fined for having them there, so just sit back and enjoy them.

I have a stripped march frog that has a cut on her foot. I have been cleaning it with saline water. This frog is wild but can't swim it just sinks.. Is there anything else I can do to help it
Discovery Centre 16 November, 2013 14:17
Hi Linda, if the Striped Marsh Frog (Limnodynastes peroni) is wild-caught it should be taken to the vet to attend to its injury, or released back where you found it. Frogs are relatively effective at repairing small injuries and the chances are good it will recover on its own. It is illegal to take frogs from the wild, even from your own property, but they can be kept in captivity under licence and if obtained from a licenced dealer. Good on you for trying to do the best for this frog.

I just found the spawn from the stiped marsh frog in one of our ponds (I live in Sydney). I can see some of the babies wriggling in the sac, however some of the eggs are white instead of like the others which are black. Are these infertile eggs? Unfortunately they laid in a pond of goldfish, I have moved the eggs into a baby fish net so they still have the same water and are protected from the goldfish. What is their survival rate if i move them to another pond with different water quality and temperature (I have native fish that are supposed to be frog friendly in this proposed pond (silly frog chose the wrong pond)). I also have an aquarium inside with stagnet water which has water plants growing happily in it, but I haven't touched it for over a year. Do you think the tadpoles will survive in this until they are a bit bigger? Thanks
Marlena 22 December, 2013 21:15
Hi, I have at least 3 male striped Marsh frogs in my yard. I have just read your posts and see that they eat snails. I have been going out at night and spraying the snails and slugs with a solution of 1 part ammonia to 3 parts water. It kills them. Will the dead snails and slugs harm the frogs? So far they are thriving, but I am concerned I have robbed them of their food source.
Discovery Centre 3 January, 2014 14:22
Hi Marlena, ammonia in general is not good for frogs. If it builds up in a pond containing adults or tadpoles, it can quickly kill them. We can't find any information regarding the effects on frogs of snails killed by ammonia, but suggest it's safer not to take the risk. In theory, the ammonia may break down before the frog eats the snail, and in theory the frog should reject any snails containing ammonia, but given how toxic it can be it may have severe effects. A safer alternative is to collect the snails and put them in the freezer overnight.
Juanita 28 September, 2014 11:48
hello, so i have just found what i suppose is a striped marsh frog in my backyard, but the problem is that i found it in a place rain water and leaves are collected and there is lots of water for it to swim in but it cant seem to get out. what should i do? help!!! i'm assuming its been there for a while now because thick slim is starting to build up around its body, but every time is swims it seems to fall of. Is this natural or is the frog just plain sick? Also just out of curiosity would i be able to keep the frog if i wanted to???? thanks :)
Discovery Centre 13 October, 2014 15:32

Hi Juanita,

The slime may have been produced by the trapped leaves soaking in rainwater rather than being produced by the frog itself. The best option is to let the frog out by placing a stick for it to climb, or by lifting it out by hand. Although Striped Marsh Frogs (Limnodynastes peroni) can be kept as pets, they must be obtained from a licenced breeder and not collected from your garden.

Greg 29 October, 2014 07:47
Hello, we've raised a single froglet from a tadpole that we've become quite attached to. We took the eggs from our fishpond to prevent them being eaten by the goldfish but now we have a froglet we're not sure how big it should be before we release him. I'd heard that goldfish might nibble off his little legs! Could you give any advice on how big they froglets should be? At the moment he has little legs and a tiny tail (about 3-4mm) there's plenty of plants and rocks in the fishpond and one of his parents has been living there happily for at least a year. Thank you!
Discovery Centre 1 November, 2014 13:00

Hi Greg,

Whilst goldfish may eat frog eggs and tadpoles, they are unlikely to consume a metamorph frog (froglet). Your pond was obviously a good habitat for the frog's parents, and with plenty of plants around the edges the froglet should be able to avoid the water-bound fish if you release it now.

Rosalie 19 November, 2014 23:08
Hi, I've got a striped marsh frog living in my garden in Sydney and I've just happily discovered a whole stack of tadpoles in the pond, however, the pond is also swarming with mosquito lavae. I was planning to clean the pond out until I saw the tadpoles. Will it harm the tadpoles if I do my best to scoop out the wrigglers? The tadpoles are there of their own accord so I figure they must like the conditions at the moment - is there anything you recommend I do to keep them alive?
Discovery Centre 26 November, 2014 10:24

Hi Rosalie, tadpoles are generally herbivorous or feed on pond detritus, but some of the larger species or individuals will feed on mosquito wrigglers. Removing the wrigglers by hand or a small net would not harm the tadpoles, which are likely to move to the bottom of the pond during the process. You could also add native fish species to the pond, as many species will eat mosquito wrigglers but leave the tadpoles alone. The Crimson-Spotted Rainbow Fish (Melanotaenia splendida) is one example from northern Victoria. Mosquitoes don't like disturbed water surfaces, so any disruption using sprinklers, bubblers or similar could reduce the number of mosquitoes.

(from Bris): Striped marsh frog (I assume, from the distinct loud TOCK noise), living in the drain within the hedge, in front of my bedroom. Has been actively TOCKING for a full year. Driving me literally insane. Starts at dusk and goes til dawn, incessantly, with no breaks. I can't cope with it any longer. How on earth do I move it on? It is a drain where I can't lift the grate. I can't stand it anymore. I would liken it to a dripping tap keeping someone awake all night. Earplugs are no longer an option. I have worn them nightly for so long that I have inflammation in my ears now. How can I move this damn frog on? Do they EVER stop TOCKING?
Goinginsane 28 March, 2016 00:03
Finally!! Someone else with the same issue!! It's nearly 11pm and I have two of the little buggers having a tock off outside my bedroom window. Has been going on for months and Slowly driving me nuts!!!!!
Janet 19 April, 2016 14:52
I'm searching to see if the off/on dripping sound I hear outside my bedroom window every night could be a frog or toad. I thought it was my neighbor's a/c leaking, but it's gone on too long. I'm thinking this might be my answer. I liken it to Chinese torture.

Hello, Just wanted to know if striped marsh frog tadpoles will go cannibalistic? Was cleaning the backyard and came across some eggs. My dog ate the adult frog so I decided to take in the eggs and raise them in a tank till I build an appropriate enclosure out the back.(yes I have appropriate licensing to keep). I researched how to move the eggs and it said most will not survive but in my case that was wrong. I have at least 200 tadpoles in the tank and they are growing rapidly. So wanted to know if I should leave them all together and let nature take its course (strong eating the weak) or if I should seperate them? Also what would one do with unwanted tadpoles? Release? Use as exotic feed for a turtle or water dragon? Any ideas would be great. Lastly I read on a thread that tadpoles will not eat fish food. False. Mine love it but I also fees them cabbage and lettuce. Eagerly awaiting a response. Thanks.
Discovery Centre 25 May, 2015 11:21

Hi Edward,

Tadpoles naturally feed on algae and in captivity will feed on boiled lettuce and cabbage, as well as some components of commercial fish food and the algae growing on the sides of the tank. So as you've probably already discovered they are not cannibalistic. Tadpoles of this species (Limnodynastes peronii) will happily live in large groups within a single tank, and 200 should be fine when they are still young. As the tadpoles increase in size, however, you may find it increasingly difficult to keep the water clean with the higher biological load, and they may simply run out of room. Returning captive frogs to the wild can be dangerous as it runs the risk of spreading chytrid fungus, and keeping native animals should always be done on the proviso that you have a plan for any offspring (or do what you can to prevent offspring being generated). Also, the licences cover the keeping of the species but not collection from the wild, even from your own garden. In all cases, the frogs need to be obtained from licenced sellers.

Hi, we have a large farm dam/wetland on King Is. contains among others lots of Striped MF's. Recently observed several egg rafts surrounded by the floating bodies of several adult frogs! A few have been mutilated to various degrees, e.g. heads off, throats ripped out, however several others appear untouched, while one has belly torn open with eggs spilling out. We have also watched a white-faced heron eating bits from the dam edge, but this doesn't seem to account for all the deaths, as some are untouched after several days. What is going on here? Natural spawning death? Competitive individuals drowning each other? Frog horror!
Gailene 2 October, 2015 16:56
I read all the posts about the striped marsh frog with interest. I've got the same problem as Fionulla (21 Jan 2015) and she didn't get an answer about what to do about the noise! We had just one loud tokking frog for over a year which was OK, just outside the bedrooms near our little waterfall pond - now there are what sounds like a dozen of them all tokking away, so between them all the noise never stops except briefly at midday. It's driving us all insane and I'd like some advice about what to do.
Goinginsane 28 March, 2016 00:04
Why is no one responding with advice on how to make them go away. The sound is like a dripping tap. Not remotely enjoyable!!!
Christiane 18 October, 2015 14:59
We have a small garden pond in inner western Sydney. About 1 year ago we had two batches of spawn laid by striped marsh frogs from our neighbour's garden, the tadpoles have all been living quite happily until the past week when they began to develop legs but sadly most of them have also suddenly died. The remaining morphs are looking sluggish and unhealthy. Nothing new in the pond or garden. Any suggestions about what has gone wrong and what we could do to prevent this happening again?
Discovery Centre 24 October, 2015 11:49
Hi Christiane,

Tadpole, metamorph and adult frog mass mortalities sometimes occur in the wild and in garden ponds with no known cause. There are always a number of potential causes, but none of them are usually obvious and can be difficult to pin down – in most cases it could be a combination of factors that otherwise wouldn’t produce major side effects. These causes can be a bacteria or virus, a pollutant, other water quality issues or oxygen starvation. The latter is unlikely to the reason for deaths of metamorphs.

Frog mass deaths are disturbing but difficult to resolve. The best option is to keep an eye on the general conditions and try to link any changes (no matter how subtle) to impacts on the frog population.

Jasmine 14 November, 2015 21:29
hi I just found a frog that my cat had in its mouth that looked like this if it would should I be worried about her? She didn't swallow it but it was in her mouth and I fear it could be poisonous
Discovery Centre 20 May, 2016 13:27

Hi Jasmine,

Few frogs from temperate regions are poisonous or exude toxins from their skin.  Toads can exude toxins and, in Australia, the Cane Toad is highly poisonous to animals.  If you are unsure of whether your cat caught a frog or a toad: Frogs have wet skin and long hind legs and toads have dry skin and short hind legs.

The toxins are fast acting and your cat would have developed symptoms quickly.  It is best to call your veterinarian as soon as possible. 

Tania 22 December, 2015 21:50
Hi, I'm worried as one of my cats just brought in what looks like a spotted marsh, it what I noticed first was him (our cat) foamy at the mouth, then I noticed the frog, R they poisonous to cats? As its not the first one that they have brought home, but this one scarred me as my baby had white foam around his mouth, I whipped it away, & foam stopped,, so hopefully it was just secretions from the frog & my baby will be ok:). Please let me know if they Are poisonous to cats as I can't find anything on the Internet regarding this. Thank you
Sandra 9 January, 2016 21:22
Hi Tania, did you find or get a reply to your question? My cat has just bought in one of these frogs, and she was also foaming at the mouth,I also can't find anything online about if they're poisonous or not ?
Discovery Centre 18 January, 2016 11:42
Hi Sandra,

A number of species of toads (such as Cane Toads) and tropical frogs (such as Poison Arrow Frogs) are toxic and often fatal to almost all animals that consume them, but this is generally not the case with temperate frog species. The froth you saw was probably generated by the frog in reaction to being attacked, or may have been produced by the cat’s mouth in response to the frog. Spotted Marsh Frogs (Limnodynastes tasmaniensis) are not known to be poisonous.

Holly 1 February, 2016 12:12
one of these guys moved into my backyard when i didnt bother emptying my kiddy pool but he definitley is no small fella. i think it would stretch out to t least 10cm and probably barely fit in my hand. should i just leave it? im not sure if it is just chilling or if it is stuck in my pool
Discovery Centre 24 March, 2016 10:45

Hi Holly, 

Frogs are good at deciding on suitable environments. If the pool is suitable and the food supply is sufficient it will hang around; if not it will move on to a more suitable habitat. So if you’re happy for it to be there, the best option is to leave it alone. You are more likely, however, to have a Pobblebonk (Limnodynastes dumerilii) than a Striped Marsh Frog (Limnodynastes tasmaniensis).

Adele Main 3 February, 2016 07:32
I have been delighted to have marsh frogs (Never seen them, but they TOC regularly) in my Canberra garden, they seem to hibernate in our cold climate, and only sound (yes, just like a dripping tap) during warm times, and usually only after rain. I was hoping that either they or their tadpoles would eat mosquitoes and mosquito larvae. Does anyone know?
Katie 20 June, 2016 07:59
I too have two of these little blighters living in the drains outside my unit. One outside my bedroom. One outside the living room. They have been there on and off for at least a year and are driving me absolutely CRAZY! They have started up again at about 3.45am this morning. Anyone who wants them is welcome to come and get them. Failing that - can anyone PLEASE recommend some methods to deter them? I don't want to hurt them - I just want them to go away and not return and not drive me mental. I note just about everyone's comments have been replied to other than the ones asking for help to make them go away?
katherine cheney 8 October, 2016 19:08
I,m really upset that now I have no frogs(striped marsh)Years ago I had so many that neighbors used to shout out at night to the frogs to shut up.Im not sure whether it's a good thing to try and restock.Is Sydney going through a frog chytrid problem.Or is there some other problem I should know about?
our dog just killed one are they poisonous 19 April, 2017 18:33
Our dog killed one are they poisonous to dogs
Katie Metcalf 5 June, 2017 16:37
Hi, I just rescued one of these frogs from Bunnings - it surely would've died as it was amongst all the fertilisers and pallets. They helped me find a box and I've let him go in my garden amongst some lush leaves. He hasn't moved for a couple of hours but looks ok. My question is should he have a pond or something as I just have lots of garden, no pond or pool. Also if he's not happy here how far will he travel to find a home he likes better. I have seen and heard lots of frogs around the house so I'm hoping he'll be ok.
