Bite force in the horned frog (Ceratophrys cranwelli) with implications for extinct giant frogs [PDF]
Scientific Reports, 2017 AbstractOf the nearly 6,800 extant frog species, most have weak jaws that play only a minor role in prey capture. South American horned frogs (Ceratophrys) are a notable exception. Aggressive and able to consume vertebrates their own size, these “hopping heads” use a vice-like grip of their jaws to restrain and immobilize prey.

Evolutionary and developmental considerations of the diet and gut morphology in ceratophryid tadpoles (Anura). [PDF]
BMC Dev Biol, 2020 Background: Before metamorphosis, almost all anuran tadpoles are omnivores. Larval carnivory occurs in some species and, it is associated with distinctive morphotypes.

Developmental changes and novelties in ceratophryid frogs. [PDF]
Evodevo, 2016 The Neotropical frog genera Ceratophrys, Chacophrys and Lepidobatrachus form the monophyletic family Ceratophryidae. Although in- and out-group relationships are not fully resolved, the monophyly of the three genera is well supported by both ...

Comparative and functional analysis of the digital mucus glands and secretions of tree frogs [PDF]
Frontiers in Zoology, 2019 Background Mucus and mucus glands are important features of the amphibian cutis. In tree frogs, the mucus glands and their secretions are crucial components of the adhesive digital pads of these animals.

Hormonal induction of spawning in 4 species of frogs by coinjection with a gonadotropin-releasing hormone agonist and a dopamine antagonist [PDF]
Reproductive Biology and Endocrinology, 2010 Background It is well known that many anurans do not reproduce easily in captivity. Some methods are based on administration of mammalian hormones such as human chorionic gonadotropin, which are not effective in many frogs.

Specific Dynamic Effect in the Horned Frog Ceratophrys cranwelli [PDF]
Copeia, 1999 Animals exhibit an increase in resting metabolic rate after feeding while they process the ingested food, a response that has been termed the specific dynamic effect. This postprandial rise in metabolism is due in part to the cost of processing absorbed nutrients, especially amino acids, and is particularly pronounced in animals such as large snakes ...
