HR-US image of a female Kaloula pulchra obtained in the transverse plane using a ventral acoustic window. The image was taken just after oviposition. Both ovaries (right ovary: Ro; left ovary: Lo) appeared as hyperechoic structures with multiple hypoechoic foci which represent follicles. The kidneys are also visible (right kidney: Rk; left kidney: Lk). This animal had free fluid (f), which is considered normal in amphibians. The fluid around the ovaries improves its margin definition.
