Elephants Once Thought Extinct Likely Survived

April 17, 2008 -- Borneo's pygmy elephants may be descendants of an extinct Javan elephant race, saved by chance by an 18th century ruler, according to a new study released Thursday.

The 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.

"If proven, this fascinating story would demonstrate that very small populations of large mammals can be saved from the brink of extinction (simply by) moving a few individuals, from a seemingly doomed population, to a different and safer habitat," the study published in the Sarawak Museum Journal says.

Study co-author Junaidi Payne said the Sultan of Java in Indonesia in the 18th century likely sent some pygmy elephants as gifts to the Sultan of Sulu in the Philippines. The Sultan of Sulu at some point apparently shipped them to Borneo and abandoned them there for unknown reasons.

"There are a number of historical records of elephants shipped between various places in Asia by rulers as gifts to impress others," Payne said.

Borneo pygmy elephants, which are genetically distinct from other subspecies, grow less than about 8 feet compared to about 10 feet in height of Asian ale elephants.

They also have babyish faces, large ears and longer tails. They are more rotund and less aggressive.

The pygmy elephants in Java were extinct by the end of the 18th century, but the few that were brought to Borneo thrived, the study found.

Historically, Borneo never had any elephants and the origins of pygmy elephants -- a distinct subspecies of its mainland Asian cousin -- remained shrouded in mystery until now.
