scuba diver
Tank-breathing explorer
A scuba diver is someone who swims underwater using a self-contained breathing apparatus—tanks of compressed air worn on the back.
Scuba divers explore reefs, investigate shipwrecks, conduct underwater research, or dive recreationally: The scuba divers spotted a moray eel hiding in the coral.
