Giant mouse lemur
Giant mouse lemur.The giant mouse lemurs (genus Mirza) are primates native to Madagascar, like all other lemurs. The two described species, the northern (pictured) and Coquerel's giant mouse lemurs, are found in the western dry deciduous forests, Sambirano valley and Sahamalaza Peninsula. In 1870, British zoologist John Edward Gray assigned them to Mirza, but the classification was not widely accepted until the 1990s, following the revival of the genus by American paleoanthropologist Ian Tattersall in 1982. Giant mouse lemurs weigh approximately 300 g (11 oz) and have a long, bushy tail. They sleep in nests during the day and forage alone at night for fruit, tree gum, insects, and small vertebrates. The northern species has the largest testicles relative to body size of any living primate. Predators of giant mouse lemurs include the Madagascar buzzard, Madagascar owl, fossa, and narrow-striped mongoose. Both Mirza species are endangered due to habitat destruction and hunting.
