Jakarta – At least four out of Indonesia's 40 primate species are in danger of extinction, in large part because they are hunted for their meat, which is a traditional medicine, animal protection group ProFauna Indonesia said Sunday.

ProFauna chairman Rosek Nursahid said the four endangered species were the Sumatran orangutan (Pongo abelii), Javanese slow loris (Nycticebus javanicus), Siau Island tarsier (Tarsius tumpara) and Simakubo pig-tailed langur (Simias concolor).

"They're still being traded; Only a few are intended for domestication, most are consumed, especially their brains and their meat," Rosek said during a rally against ape trading in Denpasar. He added that thousands of apes were traded in Indonesia every year.

Rosek said another factor threatening the apes' existence was the destruction of their natural habitats due to logging, kompas.com reported.
