The park is also home to mammals typically inhabiting forest zones, such as duikers and bushpigs, as well as two species that give the park its uniqueness: one of these is the manatee, an aquatic mammal characteristic of the Ivorian lagoons; the other is the colony of straw-coloured fruit bats that roosts on Balouate Island, which the local people believe to be a sign of the presence of their ancestors. Additionally, there are a great variety of other bats, and the islands are home to the spotted-necked otter and the African clawless otter.
