Lemurs

The Lemurs are animals in the Madagascar franchise. They lived on the island pursued by the fossa, always trying to eat them, until they came Alex, Marty, Gloria and Melman and as castaways. After an accidental roar Alex saw a spider that produced the horror of the fossa King Julien came up that could take advantage of their stay to continue keeping them away from them, until they discovered that Alex is also a predator. Fortunately the penguins were able find a substitute foof (fish) to calm his appetite.
