Another beluga whale death at SeaWorld
A two-year-old beluga whale calf called Stella had died at SeaWorld in San Antonio, Texas.
It is not yet known what caused her death but SeaWorld says she was being treated for possible gastrointestinal issues.
Stella is the second young beluga to die at the marine park this year. Both whales were the offspring of Imaq, a wild-caught beluga held at the Vancouver Aquarium.
It brings the total of beluga whales deaths in captivity this year to four. Two belugas died at Georgia Aquarium in October and June.
