Tadorna variegata (Paradise Shelduck) is a species of birds in the family Anatidae. They are associated with freshwater habitat. They are found in australasia. They visit flowers of broadleaf carpetgrass and true grasses. They are diurnal omnivores. They have parental care (pair provides care). They rely on flight and drag powered swimming to move around.

URI: https://eol.org/schema/terms/drag_based_swimming
Definition: Drag swimmers use a cyclic motion where they push water back in a power stroke, and return their limb forward in the return or recovery stroke. When they push water directly backwards, this moves their body forward, but as they return their limbs to the starting position, they push water forward, which will thus pull them back to some degree, and so opposes the direction that the body is heading. This opposing force is called drag. The return-stroke drag causes drag swimmers to employ different strategies than lift swimmers. Reducing drag on the return stroke is essential for optimizing efficiency.

corneal eyes
- URI: https://eol.org/schema/terms/corneal_eyes
- Definition: Because of the difference in refractive index between air and water (or corneal tissue), a curved cornea is an image-forming lens in its own right. Its focal length is determined by the radius of curvature of the cornea. Many corneal eyes (eg: in land vertebrates) also have lenses, but the lens is flattened and weakened compared with an aquatic lens; most of the refractive power is provided by the cornea. Corneal eyes cannot focus in aquatic habitat.
