"We believe this dolphin is part of a local pod that has learnt to steal food from the baited drumlines, however on this occasion she has managed to hook herself in the mouth," Sea World's Head of Marine Science Trevor Long told 9News. "Unfortunately the hook, which is a large shark hook, was deep within the animal's bottom jaw, so it had to be surgically removed."
Long said veterinarians determined the dolphin is about a month away from giving birth.
"It was of concern that we get this animal back out into the environment as quickly as we can so that she can have her bub in a very natural way," he said. "Everything has gone exceptionally well."
A video of the dolphin's release Tuesday off Gold Coast's Main Beach was posted to Facebook by Sea World.
