• The brant (Branta bernicla) is the smallest member of the goose family. Its body length is 596–774 mm.
• The brant cannot dive, but it is able to flip upside down and reach food on the bottom, similar to ducks.
• When in danger, the brant crouches low, pressing its body to the ground and extending its neck; it does the same on water in some cases.
