What does natatory mean?
Natatory is a formal adjective meaning relating to swimming or adapted for movement through water. It is especially used in biology and anatomy to describe limbs, organs, or other structures that function in swimming. For example, a fish’s fins and a duck’s webbed feet can both be described as natatory. The term is precise and technical, so it is more common in scientific descriptions than in general conversation. Its Latin origin connects it with the language of swimming and water, and it remains useful when a writer needs to identify a structure specifically associated with aquatic movement rather than with a broader relationship to water.
