The amount of entrained water the frog can ingest is related to its ability to actively increase its body volume. The frog's buccopharyngeal cavity (the cavity connecting the mouth and the pharynx) is very distensible and can expand substantially. It uses its entire trunk to rapidly enlarge the cavity, which expands into the lower end of the trunk.
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 ...
Ceratophrys is a genus of frogs in the family Ceratophryidae. They are also known as South American horned frogs as well as Pacman frogs due to their characteristic round shape and large mouth, reminiscent of the video game character Pac-Man.
The nickname "pacman frog" is a reference to the popular 1980's arcade game Pac-Man, where Pac-Man himself eats quite a lot, and has a mouth that takes up most of its body, much like the Argentine horned frog.
Brown individual; the color of this species is quite variable. The helmeted water toad is a robust species with a broad head and large mouth. [6] It is very large, and can reach a snout–to–vent length of up to 15.5 cm (6.1 in) in males and 32 cm (12.6 in) in females.
The presence or development of the vocal sac is one way of externally determining the sex of a frog or toad in many species; taking frogs as an example; The vocal sac is open to the mouth cavity of the frog, with two slits on either side of the tongue. To call, the frog inflates its lungs and shuts its nose and mouth.
This only happened in fish-free lakes, because only those had enough frogs and enough genetic variation to evolve resistance. So in 2006 Knapp and other researchers set about to see if the frog ...
Rheobatrachus, whose members are known as the gastric-brooding frogs or platypus frogs, is a genus of extinct ground-dwelling frogs native to Queensland in eastern Australia. The genus consisted of only two species, the southern and northern gastric-brooding frogs, both of which became extinct in the mid-1980s.
