Fanaloka vs Fossa: common questions
Are the fanaloka and fossa closely related?
Yes, both species belong to Eupleridae, a carnivore family found only on Madagascar, descended from a single mongoose-like ancestor that reached the island millions of years ago, despite their very different sizes.
Which is bigger, the fanaloka or the fossa?
The fossa is far bigger, Madagascar's largest predator, while the fanaloka is a small, civet-like carnivore closer in size to a typical civet or genet.
Why does the fossa look like a cat while the fanaloka looks like a civet?
The fossa evolved into a cat-like apex predator through convergent evolution after becoming Madagascar's largest carnivore in the absence of true cats, while the fanaloka remained closer to the smaller, civet-like body plan of the ancestral Eupleridae lineage.
