U.S. Navy Senior Chief Petty Officer Jason Sparks communicates with a young patron at Henry Doorly Zoo in Omaha, Neb., on Aug. 26, 2009. Members of Explosive Ordnance Disposal Operation Support Unit 10 took turns diving into the zoo's aquarium throughout the day as part of Omaha Navy Week events. Navy Weeks are designed to show Americans the investment they have made in their Navy and increase awareness in cities that do not have a significant Navy presence.
