Yes, ducks can indeed float in the ocean.
Ducks possess several adaptations that allow them to float effectively, not only in freshwater but also in saltwater environments like the ocean. These adaptations include:
-
Uropygial Gland (Preen Gland): This gland, located at the base of the tail, produces an oily secretion. Ducks spread this oil over their feathers during preening. This oil makes the feathers water-repellent, preventing them from becoming waterlogged and heavy.
-
Feather Structure: Duck feathers are intricately structured, with interlocking barbs and barbules that create a dense, waterproof barrier. This structure traps air within the plumage, increasing buoyancy.
-
Buoyancy Control: Ducks can adjust the amount of air trapped within their feathers to regulate their buoyancy. They can expel air to submerge themselves partially or fully.
Therefore, due to their natural oil secretion and feather structure, ducks are well-equipped to float in the ocean, regardless of the saltwater environment.
