Interspecies Conflict/tazzy


Hello, Jim!

Is there any animal on the planet that weighs the same or less than a Tasmanian devil that can defeat it in a face-to-face confrontation most of the time?

Thank you!

Hey Brad

Maybe not most of the time, but there are similarly formidable animals in that weight range. First you'd look towards the mustelid family- American and Honey badgers, smaller wolverines, a few otters, larger tayras, Yellow-throated martens and fishers and possibly grisons. Then you've got a couple of mongoose species that could give it a fight and definitely the fossa. Of wild dogs, I think there are three that would have the best chance of pulling it off- culpeos, short-eared dogs and bush dogs. Quite a few domestic dog breeds as well, like Patterdales and Jagdterries and small bull breeds. As for cats, well I think quite a few would have a chance because of their supreme killing ability. Best chances though would be Asian Golden cats, African Golden cats, Ocelots, Fishing Cats and especially Bobcats.

Away from carnivores, smaller suids and peccaries could do it. Then moving away from mammals, a number of monitor lizards would have an excellent chance.

So in summary, yeah there are animals that are of similar capabilities to the Tassie Devil. Would I favour any of them more than 50%? I'm not sure, I'd have to think about it some more.

Cheers Brad

I can answer most questions relating to real or hypothetical situations. I have a better understanding of animal behavior and specifically predatory behavior and interspecies predatory relationships. Mammals is my field of expertise but I can do my best in answering questions regarding other animals. Small mammals are my favourite matchups. One or two prehistoric match-ups is OK, but please do not focus on them as they are outside my expertise.


Even before completing my degree I considered myself an expert in mammal behavior. Doing my degree only furthered my interest and knowledge in the subject. After uni I got the opportunity to spend 6 months in South Africa and Kenya where I spent nearly every day basically observing and studying the animals of the savanna.
