ATLANTA -- The world's largest aquarium is getting even bigger.

Georgia Aquarium officials announced Tuesday a $110 million expansion that includes adding a dolphin exhibit. The addition will add another 1.3 million gallons of water to the aquarium, which will offer dolphin shows.

The dolphins will come from Marineland in Florida.

In return, Georgia Aquarium officials will make a $1.5 million contribution to Marineland, which is building a marine animal rescue and research center near St. Augustine, Florida.

"I think it's a terrific idea. People are fascinated by dolphins all over the world and living in Florida I've had a chance to see them and swim with them," said aquarium visitor Alan Smiley.

"This facility will have the ability to have many, many more. Ten or 12 I think would be a great number. But we're going to increase the population and we're going to breed the dolphins here if we can," said Georgia Aquarium Founder Bernie Marcus.

The aquarium will break ground on the dolphin exhibit this summer. Officials expect it to open by the end of 2010.
