Landmine sniffer rats

A baby giant African pouch rat begins its sniffer training in Morogoro, Tanzania. The rat is tethered by a wire to its harness as it learns to identify and mark a target scent. The rats are being used to help located the estimated 500,000 undiscovered landmines planted in Mozambique during 16 years of civil war. Image: Yasuyoshi Chiba/AFP
