Lemur

Lemurs are animals only mentioned in the How to Train Your Dragon.

Description
Lemurs are primates which can be found only in Madagascar. Even though they look like ancestral primates, they developed differently from monkeys and apes. There are around 100 living species of lemurs.

The lemur mentioned in the franchise is the ring-tailed lemur (Lemur catta), which is the most known lemur. It gets its name from its tail with black and white rings. It is diurnal, terrestrial and omnivorous. The ring-tailed lemur lives in groups of up to 30 individuals, having a dominant female instead of a male, like most animals.

Function
There is no specific function for the lemur in the franchise. In the real life, they are the most studied mammal from Madagascar due to being very close to monkeys and apes.
