Pseudacris regilla

​In 2007, the Pacific chorus frog was designated as the official amphibian of the State of Washington.​

Because Pacific chorus frogs live in every county in the state and on both sides of the Cascades, they are an excellent choice as an emblem for the whole state. The Pacific chorus frog is charming and makes beautiful sounds. Less than two inches long, they swell their throat sacs to three times the size of their heads to send their calls into the night. This amphibian is useful because it eats insects, including mosquitoes. It is recognizable by the black stripe through the eye to the shoulder, and can be brown, tan, grey or green. A native amphibian, it is preyed upon by bullfrogs, snakes, raccoons, shorebirds, hawks and ducks.

​A third grade class at Boston Harbor Grade School in north Olympia, demonstrated excellent knowledge about the political process in making this proposal to the Legislature as the project involved science, research, art, and persuasive writing.
