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]
The frogs are large, have powerful leaps, and inevitably escape after which they may wreak havoc among the native frog population. [49] Countries that export bullfrog legs include the Netherlands, Belgium, Mexico, Bangladesh, Japan, China, Taiwan, and Indonesia. Most of these frogs are caught from the wild, but some are captive-reared.

Adult frogs are themselves attacked by many predators. The northern leopard frog (Rana pipiens) is eaten by herons, hawks, fish, large salamanders, snakes, raccoons, skunks, mink, bullfrogs, and other animals. [168] A trophic pyramid showing frogs as primary predators. Frogs are primary predators and an important part of the food web.
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.
In captivity, C. cranwelli and C. ornata are the most popular species, [4] along with the "fantasy frog", a captive-produced hybrid between C. cranwelli and C. cornuta. These frogs can live in a terrarium with a floor area 8-10 times the size of the frog. [4] They commonly cover themselves with substrate or just sit contentedly in the water.
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 ...
The golden poison frog is the largest species of the poison dart frog family, and can reach a weight of nearly 30 grams with a length of 6 cm as adults. [7] Females are typically larger than males. [4] The adults are brightly colored, while juvenile frogs have mostly black bodies with two golden-yellow stripes along their backs.
