Galidiinae is a subfamily of mammals that includes the species of lemurs known as giant mouse lemurs. Synonyms for this word may include "galidiines," "galidine lemurs," or simply "giant mouse lemurs." These small primates are found only in Madagascar and are known for their nocturnal habits, long tails, and large eyes. Despite being called "lemurs," they are not closely related to the larger, more well-known lemurs found on the island. Instead, they are more closely related to other small, nocturnal primates found in Africa and Asia. As their name suggests, giant mouse lemurs are known for their rodent-like appearance and behavior.
