Bite force in the horned frog (Ceratophrys cranwelli) with implications for extinct giant frogs [PDF]

open access: yesScientific 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.

Reference intervals for hematology, plasma biochemistry, and bone mineral density in captive Ceratophrys cranwelli (Anura: Ceratophryidae)

open access: yesAnimal Diseases, 2023
Hematology, plasma biochemistry, body composition, and bone mineral density (BMD) were analyzed for 30 captive Ceratophrys cranwelli (C. cranwelli) to establish the reference intervals. There was no significant difference between males and females in all

Hormonal induction of spawning in 4 species of frogs by coinjection with a gonadotropin-releasing hormone agonist and a dopamine antagonist [PDF]

open access: yesReproductive 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]

open access: yesCopeia, 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 ...

Bioacústica del canto de advertencia de Ceratophrys cranwelli (Anura: Ceratophrydae) Bioacoustic of the advertisement call of Ceratophrys cranwelli (Anura: Ceratophryidae)

open access: yesRevista de Biología Tropical, 2013
El canto de advertencia en anuros es especie-específico, pero como los anfibios son organismos ectotermos, las variables acústicas pueden estar afectadas por la temperatura.

Ontogeny of secondary sexual characteristics using morphometrics and urinalysis in premature Cranwell’s horned frogs (Ceratophrys cranwelli)

open access: yesProceedings of the West Virginia Academy of Science
Cranwell’s horned frogs (Ceratophrys cranwelli), also known as Pacman frogs, are commonly kept as pets in the United States due to their basic husbandry needs and charismatic appearance. Secondary sexual traits usually appear in frogs after sexual maturity, which occurs at about a year old in C. cranwelli.
