Four endangered pygmy elephants have been found dead in Malaysia, adding to the 10 carcasses discovered earlier this month, according to wildlife officials. Laurentius Ambu, the wildlife department director of the Malaysian state of Sabah on Borneo island, told the AFP news agency on Wednesday that probably the elephants had ingested poison spread by oil palm plantation workers to keep “pests” from eating the palm fruit. Ambu also said that more carcasses are likely to turn up since elephants tend to move in herds.
