Karimi's fat-tailed mouse opossum (Thylamys karimii) is a species of opossum in the family Didelphidae.[2] It is endemic to central and northeast Brazil, where it is found in the cerrado and caatinga at elevations from 300 to 1100 m.[1] This opossum is crepuscular and mostly terrestrial; its omnivorous diet includes leaves, insects and small vertebrates.[1] Its head-and-body length is about 95 millimeters, and its tail length is about 72 millimeters. It is very similar to T. pallidor. Its tail may be nonprehensile.[3] The species is named after Iranian epidemiologist Y. Karimi.[4] It is threatened by habitat destruction and fragmentation due to agriculture and ranching.[1]
