The sharks at the Henry Doorly Zoo's "Shark Reef" have some big company now.
Divers released two green sea turtles into the aquarium.
They're 15-years old and had been in a marine research facility in Nova Scotia in a 3,000 gallon tank.
Naturally the 450-thousand gallon tank at the zoo will allow them to spread their fins.
"The public finds turtles very interesting," Zoo CEO Dennis Pate said. "They're a little tough to wrangle for our divers when they are in there because they're spunky. It's interesting, there's some connection between kids and turtles and when you add sea turtles to the mix it goes up exponentially."
Green sea turtles are endangered.
These two are named Ambrose and Merv.
They join Harold, a loggerhead turtle, living in the shark reef.
