aquatic mammal exhibit
A zoo habitat for housing and displaying seals, dolphins, or other aquatic mammals.
An aquatic mammal exhibit is a zoo enclosure, habitat, or housing facility for any kinds of underwater-dwelling mammals, including sea lions, dolphins, porpoises, orcas, belugas, and walruses.
The display can concern one or several kinds of aquatic mammals. It need not include all the species listed in the definition.
An aquarium can include such animals, but a separate aquatic-mammal display in a zoo retains its animal-exhibit use under the stated distinction.
