Pygmy elephants

Two pygmy elephants cross the road in Taliwas forest on Malaysia's Sabah state on Borneo Island. Borneo's pygmy elephants may be descendants of an extinct Javan elephant race.

A new study suggests that a small number of opposite-sex elephants can produce a thriving progeny of thousands if left undisturbed on an island, giving fresh hope to conservationists trying to protect nearly extinct species of large mammals.
