Gunther's Amoy frog, Guenther's Amoy frog, Günther's frog, Guenther's frog, Günther's red-and-black frog or Gunther's brown frog (Sylvirana guentheri) is a frog from Vietnam, China and Taiwan. People have brought this frog to Guam.[1] It can live as high as 1100 meters above sea level.[2]

Appearance[change | change source]

The adult male frog is 6.3 to 6.8 cm long and the adult female frog is 7.5 to 7.6 cm long. The hind legs are about one and a half times as long as the body. It has vomerine teeth and a large tongue. It has a fold of skin on each side of its body, running from the eye down to the hip. This frog has a brown or yellow-brown back and a white belly.[2]

Life cyle[change | change source]

The female frog lays eggs in rice fields and streams where the water does not move quickly. The tadpoles are silver-white in color. They have stripes running from their noses to their eyes and a dark spot behind each eye.[2]

Chemicals[change | change source]

This frog makes chemicals on its skin. It makes (Val1)-bradykinin to stop larger animals from eating it. It also has antibiotics on its skin: guentherin, brevinin-2GHa, brevinin-2GHb, brevinin-2GHc, and temporin-GH.[2]

Danger to humans[change | change source]

The parasite Angiostrongylus cantonensis, or rat lungworm, can live in this frog. This parasite gives humans the disease angiostrongyliasis[2] and makes the membranes around the brain swell, which is very dangerous.[3]
