Ultrastructural changes in the follicular epithelium ofCeratophrys cranwelliprevitellogenic oocytes [PDF]
Zygote, 2007 SummaryIn this work we carried out ultrastructural, autoradiographic and biochemical analyses of the follicular epithelium duringC. cranwelliprevitellogenesis. This study revealed that the follicular epithelium in early previtellogenesis is constituted of a single layer of squamous homogeneous cells.

Metamorfosis del aparato digestivo de larvas carnívoras de Ceratophrys cranwelli (Anura: leptodactylidae) [PDF]
Canadian Journal of Zoology, 2001 Las larvas carnívoras de Ceratophrys cranwelli presentan un tubo digestivo más corto que la mayoría de las larvas de anuros, tiene 6 veces la longitud del cuerpo del renacuajo y se caracteriza también por tener un estómago larval. El presente trabajo tiene como objetivo el determinar el grado de transformaciones en la cavidad bucofaríngea y tubo ...

Ultrastructural characteristics of the follicle cell-oocyte interface in the oogenesis of Ceratophrys cranwelli [PDF]
Zygote, 2002 In this work we carried out an ultrastructural analysis of the cell interface between oocyte and follicle cells during the oogenesis of the amphibian Ceratophrys cranwelli, which revealed a complex cell-cell interaction. In the early previtellogenic follicles, the plasma membrane of the follicle cells lies in close contact with the plasma membrane of ...

Sustained Force Production by Jaw Muscles of Specialized megalophagous Frogs (Ceratophrys SPP.) [PDF]
, 2022 Horned frogs (Ceratophrys spp.) are unusual among anurans in their predatory behavior. Most frogs have weak jaws that play a relatively minor role in tongue-mediated prey capture.

Underwater sound emission as part of an antipredator mechanism in
Acta Zoologica, 2013 AbstractWe report the emission of underwater sounds in the tadpoles of a second member of the family Ceratophryidae, Ceratophrys cranwelli. These tadpoles produce a short metallic‐like sound, which consists of short trains of pulses at Gosner stages 25, 28, and 37.
