Ethiopian wolves don't look much like the grey wolves you might have seen in books. They are slimmer, with bright rust-red fur, white legs and a black-tipped tail. They look a bit like a long-legged fox. They live above 3,000 metres - higher than most mountains in Europe.
Unlike most wolves, Ethiopian wolves hunt alone, not in packs. They mostly eat tiny mole-rats - small rodents that pop their heads out of holes in the grassland. A wolf might sit completely still by a hole for ten minutes, waiting for the perfect moment to pounce.
But they still live in family groups. Several wolves - parents, brothers, sisters, aunties and uncles - share a territory and help look after the cubs together. Everyone takes turns playing with the youngsters, bringing them food and watching over them.
There are only about 500 Ethiopian wolves left in the wild. That's why teams of vets, scientists and rangers from Ethiopia and around the world are working together to look after them - vaccinating them against diseases that pet dogs carry, and protecting their mountain home. Every cub born is a victory.
