What does natatorial mean?
Natatorial is a formal adjective describing something connected with swimming. It is especially used for the physical structures, abilities, and behaviour that enable an animal to move efficiently through water. A seal's natatorial skill, for example, depends on features such as a streamlined body and powerful flippers, while a duck may possess natatorial adaptations such as webbed feet. The word is not generally used to describe an entire aquatic habitat or organism; terms such as “aquatic” and “amphibious” are more appropriate in those contexts. Natatorial is therefore chiefly a scientific or descriptive term, and its relative rarity gives it a learned, technical tone. It derives from a Latin word meaning “swimmer,” reflecting the long-established connection between the adjective and the action of swimming.

Natatorial comes from the Latin for “swimmer,” so even its spelling preserves the image of an animal moving through water.

Where does natatorial come from?
Natatorial derives from the Latin adjective natatorius, meaning “of or for a swimmer” or “pertaining to swimming.” This was formed from natator, meaning “swimmer,” which in turn comes from the Latin verb natare, “to swim.” The English word entered use in the 17th century in descriptive and scientific contexts, especially in the study of animals and their bodily adaptations.
