The second silver coin adorned by a patina from the cycle of the Czech Mint The animal record holders was dedicated to the golden poison frog. This frog is the most poisonous creature of the planet.
The golden poison frog occurs in three different color variations - green, yellow and orange - and this alert color warns anyone who tries to irritate or eat it. Even though golden poison frogs are smart and intelligent hunters, they do not use their poison to attack. Batrachotoxin - a rare alkaloid poison that permanently prevents nerves from impulses and leaves muscles in a shrunk condition - is contained in their skin and protects them from predators. The golden poison frogs exclude it only under pressure, in self-defense, and thus have no natural enemy. A small frog has only one milligram of lethal substance. But it is enough to kill ten thousand mice, twenty people or two African elephants. This is used by native Colombians from Chocó tribe, who collect their poisons and apply them to the spikes of arrows. The golden poison frog itself does not produce poison. It synthesizes it from food which is probably a beetle of the Acrochordidae. Frogs kept in captivity that eat crickets or flies, are toxic, but it may take years to accumulate poison.
The reverse side presents a detail of the frog head surrounded by the Latin name PHYLLOBATES TERRIBILIS. The individual details of the relief excel due to the decent patina. The composition of the obverse side, which is common to all the coins of the cycle, consists of a pair of natural sceneries and the attributes of the island of Niue, which provides the Czech Mint with a foreign license to issue its own commemorative coins. These are the name and the portrait of Queen Elizabeth II, the nominal value of 1 DOLLAR (NZD) and the year of issue 2019.
