 of the genus Cricetomys. Found in a wide variety of habitats, including farmland, in sub-Saharan Africa north of South Africa, giant pouched rats resemble a very large house rat, to which they is not closely related. They have large cheek pouches like those of the hamsters, which they use for transporting foraged food back to the burrow, and have gray to brown fur with lighter underparts and a long scaly tail. They are largely nocturnal and omnivorous, feeding on vegetation and insects and other small invertebrates, but they favor palm nuts. The largest, the Gambian, or African giant, pouched rat, may reach 3 ft (90 cm) in length, half of which is the tail, and weigh up to 6.5 lb (3 kg). Gambian pouched rats, which have a keen sense of smell, have been trained to work with human handlers to detect land mines and identify tuberculosis in sputum samples. Giant pouched rats are hunted for food in Africa, and have been kept as pets in Europe and North America. Giant pouched rats are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

Los antecedentes de esta justificacion, a su vez, son dos: a) la especie que es mas usada en el mundo (y tambien por la Policia Nacional de Colombia) como apoyo para deteccion de explosivos es el perro (vease Mendez Pardo & Perez-Acosta, 2009c), pero se trata de una especie que por su peso puede ser capaz de activar una mina; b) los primeros roedores exitosamente usados para la deteccion de minas antipersonales son de la especie Cricetomys gambianus, rata gigante africana, (vease Poling, Cox, Weetjens, Beyene & Sully, 2010; Verhagen, Weetjens, Cox & Weetjens, 2006), que es una especie nativa (es decir, que no podria ser facilmente reproducida en otros lugares del mundo) y cuyo peso promedio adulto es 1500 gramos (tres veces la rata de laboratorio).
