arctos is not an adjetive and the remaining ones are all masculine or femenine gender, not neutral
There are also a lot of neutral adjetives that doens't end in -anus, but it's fairly usual overall for those referring to places (such as malayanus)
Not to be confused with Fossa fossanaCryptoprocta ferox always gets me.

The American robin: Turdus migratorius. I also like the Steller's sea lion: Eumetopias jubatus. Only because the males look and sound like Jabba the Hutt when they're lying on rocks.
I had wondered what that meant since I later on saw that in the cheetah's Latin name.a lucky co-incidence, jubata/um/us is Latin for maned.
Of course Steller's Sealions have manes - that's why they are called sealions: the males of all species have manes. The Cheetah's scientific name comes from the cubs which have an extremely obvious white mane (theorised to make them resemble Ratels). Simply looking at a photo of an Orinoco Goose will show why they are "maned" - the feathers on the back of the neck are in furrowed rows where the dark feather-bases show. The Green Crested Lizard is named jubata for the crest behind the head.Coincidence? Maybe the only fun fact is that both Steller's sea lion and cheetah doesn't have a mane despite their names meaning maned...? (and same for the Orinoco goose, or the lizard Bronchocela jubata...).
