The Aquaphone is a phone. Its receiver resembles a Shellphone. It has a metallic base, with multiple visible screws. It has a red buzzer on the base that flashes and makes dolphin chirps when being called. Attached to the base is the receiver, which looks similar to the Magic Conch shell from the episode "Club SpongeBob." The receiver is a shell with a wire coiling down to the base of the phone.
In the episode "Mermaid Pants," the phone looks slightly different, due to the light bulb not constantly having a reddish color.
