Ovis is a genre of animals that belongs to the family of bovids, which includes domestic sheep; in the case of mouflon, it is a wild species, although its introduction in Spain happened for hunting interests.

Mouflons present clear sexual dimorphism; males weigh 40 to 60kg, females instead weigh 30-40kg. Males can have very different horns, whilst females present horns only 15% to 60% of the times and in small size (15cm maximum). The fur coat is brown and creamy tones, the inner part of the body is white and they also have white patches, in the shape of a riding saddle.

It is not considered an invasive species in Spain, but its irresponsible introduction can do ecological damage, as other native ungulates compete for the same resources.

The mouflon is not listed on the IUCN Red List of Endangered Species.
