Camden Adventure Aquarium will celebrate World Ocean Day beginning at 10 a.m. Sunday with a full day of activities and attractions dedicated to changing the way families and friends look at oceans, the creatures and habitats they house, and the effects people's actions have on them.

In addition to eco-friendly exhibits and activities presented by conservation-minded organizations, including the New Jersey Wetlands Institute, the Aquarium will feature an appearance by comedian Joe Piscopo. He plans to entertain while teaching visitors about how to make a positive change in the environment. The performer then will lead a World Ocean Pledge to keep oceans clean, which guests will be able to take during their visit.

Making a positive change and raising awareness of the world's oceans will also provide themes for the aquarium's seal presentation. A 530-pound artificial reef ball will be placed in the aquarium's underwater exhibit. Visitors can learn about seafood, dive equipment, and the care of the aquarium's animals throughout the day.

World Ocean Day, 10 a.m.-5 p.m. at the Camden Adventure Aquarium, 1 Aquarium Dr., Camden. Aquarium admission: $18.95, $14.95 for children ages 2-12. Information: 856-365-3300 or www.adventureaquarium.com. A schedule of activities will be provided on event day.
