About the Southern Leopard Frog
Lithobates sphenocephalus or Rana sphenocephala, commonly known as the southern leopard frog, is a medium-sized anuran in the family Ranidae (the true frogs). The southern leopard frog is one of the 36 species currently or formerly classified in the Rana genus found in North America. It is native to eastern North America from Kansas to New Jersey to Florida. It is also an introduced species in some areas.
This frog is up to 13 cm (5.1 in) long. Males at sexual maturity average 52.9 mm (2.08 in) snout to vent length and females average 63.8 mm (2.51 in) SVL. 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 tympanum. 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 "ratchet-like trill", "chuckling croak", or a "squeaky balloon-like sound".
The larva is mottled, and the eyes are positioned on the top of the head. It grows to 7.6 cm (3.0 in) in length before maturing. The female lays an egg mass that is "baseball-sized" when close to hatching time, and contains up to 1,500 eggs... Wikipedia →
