An Audacious Maneuver: First Record of in the Marine Environment.

The Güiña (), the smallest Neotropical feline, inhabits central and southern Chile and western Argentina. This communication reports the first documented instance of a güiña swimming in a marine environment, observed in the Refugio Channel, which separates Refugio Island from the mainland in Northern Patagonia, Chile. In April 2023, a local resident recorded video footage of a güiña swimming near the eastern shore of the channel, emerging from the water, shaking off, and climbing a tree to groom itself.
