Zoo spokesman Agus Supangkat said a 7-year-old giant lizard was found dead yesterday in his cage at the zoo in Surabaya, Indonesia's second-largest city and the provincial capital of East Java. A day earlier, a pregnant barking deer died shortly after a visitor reported to a zookeeper the animal was having convulsions and was foaming at the mouth.
Supangkat denied any negligence, and said a police forensic team was performing autopsies as part of an investigation to determine the cause of deaths.
The facility that houses 3,500 animals has long been plagued with problems, including premature deaths, uncontrolled breeding and a lack of funding. An online petition has called on the government to close the facility, dubbed "the zoo of death."
Last month, an African lion was found hanged on a steel cable inside its cage and the zoo's sole female wildebeest died of a suspected stomach problem due to hot weather and humidity.
