State flag
The "landvættir" also decorate the obverse (front) of the Icelandic króna coins, but animals of the ocean (fish, crabs, and dolphins) appear on the reverse (back). The Icelandic presidency uses a swallowtailed Icelandic flag with the coat of arms. The National Commissioner of the Icelandic Police uses a white flag with the coat of arms, when the use of the State flag is not warranted, and some other state services do as well.
