The goliath frog (Conraua goliath), otherwise known commonly as the giant slippery frog and the goliath bullfrog, is a species of frog in the family Conrauidae. The Goliath frog is the largest living frog. [3] [4] Specimens can reach up to about 35 centimetres (14 in) in snout–vent length and 3.3 kilograms (7.3 lb) in weight. [5]
However, there is a correlation found with size of prey relative to body size of the bullfrog. Juveniles and adults typically go after prey that is relative to their own body size. [ 52 ] The bullfrog is able to make allowance for light refraction at the water-air interface by striking at a position posterior to the target's perceived location.
Once the predator is removed, the growth rate of the tadpole returns to, or even exceeds, baseline. This influence of predator threat is only significant during early tadpole development. [28] One of the common frog's most pervasive predators is the red-eared slider (Trachemys scripta elegans), which is a very invasive species of turtle.

Frogs range in size from Paedophryne amauensis of Papua New Guinea that is 7.7 mm (0.30 in) in snout–vent length [48] to the up to about 35 cm (14 in) and 3.3 kg (7.3 lb) goliath frog (Conraua goliath) of central Africa. [49] There are prehistoric, extinct species that reached even larger sizes. [50]
The males weigh up to 1.4 kg (3.1 lb) and grow to 24.5 cm (9.6 in) in snout–to–vent length. Females are half the size of males, which is unusual, considering that most female amphibians are (generally) larger than males, to help the amplexus.
The white-lipped tree frog reaches 11–14 cm (4.3–5.5 in) in length. [5] Females are larger than males, and have thicker skin in correlation with the difference in body size. [6] Its dorsal surface is usually bright green, although the colour changes depending on the temperature and background, and can be brown. The ventral surface is off ...
Breviceps fuscus have a round body with short limbs and toes. Its feet are inward facing which allows the frog to burrow much more effectively. They grow to about 40–51 mm (1.6–2.0 in) in snout–vent length.This species can also live anywhere from 4 to 15 years in age. [7]
