There are 3 species of lemurs on the canal islands opposite the camels and onagers which include
White belted ruffed Lemurs
Black lemurs
Alotran gentle lemurs
On Lemur Island is mainly the bachelor group of ringtails
And in the walk-through there are ring tailed , red ruffed , crowned and and red bellied
And nearby from there is a pair of coquerels sifaka which live where the black lemurs used to live
With the ring tails they have two groups a bachelor group and a breeding group however they rotate the groups regularly e.g one day the breeding group will be on the island and the other day the breeding group will be in the walkthrough when I last visited The bachelor group were in the walk through and the breeding group were on the island
