Orlando SeaWorld posted a statement on its Facebook page Friday confirming the death of Nanuq, a male beluga estimated to be around 31 or 32 years old.
SeaWorld says Nanuq was being treated by veterinarians for an infection associated with a fractured jaw, an injury that resulted from an "interaction between two animals that were part of a compatible social group."
The cause of death is not yet known, and a post-mortem examination has been scheduled, although results are not expected for six to eight weeks.
The Vancouver Aquarium says Nanuq was transferred to Orlando in 1997, as part of a co-operative program to manage the genetic diversity of belugas in human care.
The aquarium says that in 1995 Nanuq sired a female beluga named Qila, who continues to live at the Vancouver Aquarium, and staff are deeply saddened by the death.
