Hyenas Are As Bright As Primates

They were depicted as slobbering, slow-witted beasts by Disney in the hit movie The Lion King, but hyenas are far more intelligent than they have been given credit for. New research has revealed the African carnivores are adept at solving problems and can even 'count.' Scientists now believe the animals may have intelligence levels that match some primates.

Hyenas, which are highly social, have been found to assess the size of a competing pack which is invading their territory, by listening to their calls. They will only confront the intruders if the 'count' shows they have a numerical advantage.
