What does cottontail mean?
A cottontail is a small North American rabbit belonging to the genus Sylvilagus, distinguished by its short, rounded tail that is white on the underside and resembles a puff of cotton. Several species exist — including the eastern, desert, and mountain cottontails — but the eastern cottontail (Sylvilagus floridanus) is by far the most familiar and widespread, ranging across much of the United States and southern Canada. Cottontails are solitary, crepuscular animals that favour brushy edges, meadows, and suburban gardens, where they feed on grasses, clover, and other low vegetation. Their habit of freezing motionless before bursting into a zigzag sprint makes them a classic subject of wildlife observation. The word is neutral in tone and common in both scientific and everyday contexts. Because these rabbits are so visible to gardeners, hunters, and nature lovers alike, "cottontail" has also become an affectionate shorthand for any wild rabbit seen close to home.

It arose as a descriptive name for rabbits whose fluffy white tails resembled tufts of raw cotton. The compound is native to English and emerged in North American usage, where the rabbits themselves are endemic; related descriptive animal names using "cotton" include "cottonmouth" and "cottonwood."
How cottontail is actually used
