In Madagascar, what type of lemur is Mort?

In Madagascar, Mort is depicted as a mouse lemur.

Mort is a small lemur who lives with King Julien’s group after Alex and the other New York animals reach Madagascar. His tiny size, large eyes and nervous manner are recurring visual and comedic traits throughout the films. He is especially associated with his intense fondness for Alex’s feet, a running gag in the franchise.

Mouse lemurs are real Madagascan primates and are among the smallest living primates. Several mouse lemur species exist, but the films use the broader character description rather than identifying Mort with one precise biological species. That makes “mouse lemur” the appropriate answer rather than a particular species name.

Mort is sometimes mistaken for a juvenile ring-tailed lemur because he is part of the same fictional lemur community. Ring-tailed lemurs are larger and have distinctive striped tails, while Mort is designed as a much smaller mouse lemur.
