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]
Cuban tree frogs are the largest tree frogs in North America, ranging from 2 to 5.5 inches or (5 to 12.7 cm) in length. [8] Cuban tree frogs are mostly gray, brown, or green, with young frogs having more green coloration than adults. These frogs have rough, warty skin with blotchy or mottled patterning. [9]
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.
The mountain chicken is one of the largest frogs in the world, the largest in its family Leptodactylidae and the largest frog native to the Caribbean. It can reach 1 kg (2.2 lb) in weight and up to 22 cm (8.7 in) in snout–to–vent length, although a more typical adult size is 17–18 cm (6.7–7.1 in).
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.
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.
Beelzebufo most likely was a predator whose expansive mouth allowed it to eat relatively large prey, perhaps even juvenile dinosaurs. [ 9 ] [ 10 ] Bite force measurements from a growth series of Cranwell's horned frog ( Ceratophrys cranwelli ), suggest that the bite force of a large Beelzebufo —skull width 15.4 cm (6.1 in)—may have been ...
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.
