The term 'Wide Swimmer' can be solved by the 5-letter word 'MANTA'. MANTA rays are a species of ray found in tropical and subtropical waters. They are the largest of the ray species, with some specimens reaching up to 7 meters in width. MANTA rays are filter feeders, meaning they feed on plankton and other small organisms. They are also known for their acrobatic behavior, often leaping out of the water and performing somersaults.
