The Pittsburgh Zoo & Aquarium is mourning the loss of another animal, just days after a young elephant died suddenly.
The Zoo says popular sea lion Seahawk died this past Friday suddenly.
“Hawk had been exhibiting unusual behaviors and refused food for several days,” Zoo officials said in a post on Facebook.
Hawk, as he was better known, has sedated so doctors could better diagnose his condition.
But, he had an adverse reaction and did not survive the procedure.
Hawk was 18-years-old.
He was rescued in 2006 as a pup after he was orphaned off the cost of California.
A day earlier, 2-year-old elephant “Tsuni” died after a sudden and brief battle with a virus that affect elephants.
