HOUSTON—The Houston Zoo is mourning following the death of a 2-year-old elephant named Mac.

Mac — the largest Asian elephant born in captivity at 384 pounds — died Sunday night after contracting elephant herpesvirus.

Mac was born in October 2006, and the zoo says that Mac was playful, intelligent, curious and mischievous — and quickly became a favorite of zoo staff and visitors.

Zoo spokesman Brian Hill says Mac’s mother, Shanti, and aunt, Methai, were with him when he died.

A necropsy will be conducted.
