Meet Mystique, an incredibly intelligent 29-year-old male humpback dolphin. Did I mention that this special dolphin is a treasure hunter? In exchange for food or rewards, the friendly mammal offers an employee or any other person who approaches him with curious items from the sea:
"What we have to do is give him a fish in return.
"We haven't trained him, but he has trained us to do this.
"He gets under it [and] if he drops it too far out, or we say 'come on, that's not good enough', then he gets underneath it and brings it to us."
The items have included bottles, big bits of timber, shells, and wood, which are brought in on his beak.
"We swear he has a collection waiting to bring to us," Lyn McPherson said.
