Southern Leopard frog

Description:

The southern leopard frog (Lithobates sphenocephalus[1][3] or Rana sphenocephala[4][5][6]) is a species of true frog. It is native to eastern North America from Kansas to New York to Florida. It is also an introduced species in some areas.[1] This frog is up to 13 cm long. It is green or brown in color with a yellowish ridge along each side of the back. Rounded dark spots occur on the back and sides; a light spot is seen on each eardrum. The male has larger fore limbs than the female. The breeding male's vocal sacs are spherical when inflated. The call is described as a "ratchetlike trill",[7] "chuckling croak",[8] or a "squeaky balloon-like sound".[9] The larva is mottled, and the eyes are positioned on the top of the head. It grows to 7.6 cm in length before maturing. The female lays an egg mass that is "baseball-sized" when close to hatching time, and contains up to 1500 eggs.[7]
