Abstract:

Ceratophrys is the most diverse and widely distributed genus of Ceratophryidae, the clade of South American horned frogs. Numerous anuran fossil remains, including several fossil species, have been assigned to this genus. However, this seemingly extensive fossil record is problematic because several of the fossils are not properly identified and most of the taxonomic assignations are not justified. The present study traces all the fossil material attributed to Ceratophrys, clarifying, when possible, institutional allocations. Each of the remains was examined and its taxonomic assignation revis

Abstract:

AbstractA new octoploid species of Ceratophrys from the northeast of Brasil is described. The species of this genus are compared using morphological, morphometrical and cytometrical data. A tentative cladogram for the genus Ceratophrys is given, and a possible correlation of ecological preference and ploidy level is briefly discussed.

A two-year-old pet male albino Ceratophrys cranwelli was presented exhibiting lethargy, weight loss, and anorexia, persisting for two months. Clinical examination revealed a fracture localized to the proximal third of the left femur accompanied by an osteolytic process.

Abstract:

SUMMARY Calicivirus isolations were made from 4 poikilothermic species in a zoologic collection. Viruses were recovered from 8 asymptomatic Aruba Island rattlesnakes (Crotalus unicolor, rectal swab samples) and from 8 symptomatic animals (4 Aruba Island rattlesnakes, 2 Bell's homed frogs [Ceratophrys orata], 1 rock rattlesnake [C lepidus], and 1 eyelash viper [Bothrops schlegeli] tissue samples obtained at necropsy). On the basis of cross-neutralization test results, the 16 isolates were antigenically indistinguishable and were considered to represent a unique calicivirus serotype, tentatively

Abstract:

The frog species Ceratophrys joazeirensis Mercadal, 1986 is only known from the Caatinga (semi-arid savanna) and, until recently, from the type locality of Juazeiro, State of Bahia, Brazil. It has now also been found in the States of Paraíba and Rio Grande do Norte, in environments of hypo-xerophylic Caatinga. Cytogenetic and comparative analysis of the cranial morphology of C. joazeirensis and C. aurita (Raddi, 1823) were undertaken. The karyotype of the species is also shown for the first time. The results show important differences in the cranial morphology between C. joazeirensis (8n) and

Abstract:

We describe for the first time the feeding ecology of the Pacific horned frog (Ceratophrys stolzmanni), as inferred through gastrointestinal tract content analysis and behavioural observations in its natural habitat. Ingested prey in adults ranged from mites and various insects to frogs and snakes. Prey items predominantly consisted of gastropods, non-formicid hymenopterans, and centipedes. We found no relationship between the size of the predator and the prey ingested, in terms of prey size, volume or number of items ingested. Additional direct observations indicate that all post-metamorphic

Abstract:

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 the oocyte, with no interface between them. In the mid-previtellogenic follicles the follicle cells became more active and their cytoplasm has vesicles containing granular material. Their apical surface projects cytoplasmic processes (macrovilli)

El objetivo de la revisión parcial de la colección de anfibios del Instituto Nacional de Biodiversidad fue el de identificar especímenes que presenten malformaciones. Se identificó 14 especímenes pertenecientes a siete especies de anuros determinados taxonómicamente (Incilius coniferus, Rhinella ceratophrys, Oophaga sylvatica, Scinax quinquefasciatus, Leptodactylus mystaceus, Rana palmipes y Pristimantis lanthanites). Se muestra que ocho especímenes presentan Ectrodactilia, tres presentan Braquidactilia y dos presentan Polidactilia. Se halló que 11 de los 14 registros pertenecen a la zona fron
