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 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).
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.

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 ...
In the late 1960s, an expedition led by Jacques Cousteau reported Titicaca water frogs up to 60 cm (2 ft) in outstretched length and 1 kg (2.2 lb) in weight, [11] [12] [13] making these some of the largest exclusively aquatic frogs in the world (the exclusively aquatic Lake Junin frog can grow larger, as can the helmeted water toad and African goliath frog that sometimes can be seen on land).
