A dolphin swims by at an exhibit at the National Aquarium in Baltimore. The aquarium hopes to relocate its dolphins to a sanctuary off the coast of Florida or in the Caribbean.

The National Aquarium in Baltimore is located right on the city's Inner Harbor.

The dolphins at the National Aquarium are being prepped for release into a sanctuary.

The umbrellas near the National Aquarium's dolphin tanks are meant to prepare the animals for what life will eventually be like in an open air sanctuary.

Megan Anderson, an employee of the aquarium, talks with curious visitors about a glowing globe that displays different worldwide maps, one of which show the weather.

Visitors watch creatures swim inside the aquarium including Calypso, a three-legged green sea turtle.
