Etymology: Mobula is a scientific name first. It was created for a genus of rays, and the word reached everyday English as a label for those animals rather than as a folk term passed down by fishermen. The naturalist Constantine Rafinesque is credited with establishing the genus. The name is most likely built on the Latin "mobilis," meaning "movable" or "agile." That suits rays known for leaping clear of the water and gliding through the sea in loose, graceful loops. The connection is probable rather than documented, so it is best read as a reasonable reading of the name's sound and sense.
