Adopt an Animal

The National Aquarium Aquadopt program has recently been discontinued. But don't worry, our 20,000 animals are still receiving world-class care. If you would like to help, please consider making a donation at


National Aquarium - Atlantic bottlenose dolphin
Did you know?

Dolphins breathe through the blowholes on top of their heads. Each time a dolphin surfaces, the flap over its blowhole opens. The dolphin then rapidly exhales and inhales, and the flap closes. In one breath, dolphins may exchange up to 90% of the air in their lungs, compared with a human's air exchange, which is approximately 15%.

The puffin’s bill is brightest during the breeding season. When the birds return to sea at the end of the breeding season, the layers of the bill molt.
