The Nehru Zoological Park (Hyderabad) has lost one more precious primate, a 23-year-old capped langur. The langur died of multiple organ failure, zoo officials said. Curator HM Haneefulla said the beast had stopped taking food from May 13 and efforts to save it failed. A Nilgiri Langur too had died at the Zoo Park last month. Officials said that the endangered mammal was brought from Arignar Anna Zoological Park, Chennai, about five years ago. Aged about 10 years, the female primate was found dead in the ‘night house.’ There were no signs of external injuries on its body. A postmortem conducted by veterinary doctors from the zoo park and scientists from LaCONES srevealed that the death could have occurred due to severe gastritis.
