Cleveland has a new attraction that adds salt-water sharks to the city's waterfront mix.

The $33 million Greater Cleveland Aquarium was scheduled to open Saturday in a renovated streetcar powerhouse. It's located alongside the Cuyahoga (ky-uh-HOH'-guh) River and has a 150-foot tunnel offering a close-up view.

It's the only freestanding aquarium in Ohio and has a million gallons of water in 40 tanks. The exhibits include sharks and fish that inhabit coral reefs. Hermit crabs, Atlantic Stingrays and Bahama starfish are within reach in a touching pool.
