what's the measurements for a dart board
Darts A regulation board is ​17 3⁄4 inches (451 mm) in diameter and is divided into 20 radial sections. Each section is separated with metal wire or a thin band of sheet metal.[5] The best dartboards have the thinnest wire, so that the darts have less chance of hitting a wire and bouncing out. The numbers indicating the various scoring sections of the board are also normally made of wire, especially on tournament-quality boards. The wire ring on which the numbers are welded can be turned to facilitate even wear of the board. Boards of lesser quality often have the numbers printed directly on the board.
Poison dart frog Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow frog) is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America.[2] These species are diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity, while others have cryptic coloration with minimal to no amount of observed toxicity.[3] The species that have great toxicity derive this from their diet of ants, mites and termites.[3][4] Other species however, that exhibit cryptic coloration and low to no amounts of toxicity, eat a much larger variety of prey.[4] Many species of this family are threatened due to human infrastructure encroaching the places they inhabit.
