Feeding mechanisms in two treefrogs, Hyla nana and Scinax nasicus (Anura: Hylidae)
TLDR
The feeding modes of Scinax nasicus and Hyla nana tadpoles are defined and the reduction of the buccopharyngeal and branchial basket structures, together with the high lever–arm ratio and the great development of the depressor muscles of thebuccal floor are indicative of macrophagous feeding.
Eco-morphological patterns of the sagitta of Antarctic fish
TLDR
E, R and S-values could be used to characterize the sagittae of the Antarctic fish and could be considered as a useful tool for fish ecology studies.
Otolith and vertebral morphology of marine atherinid species (Atheriniformes, Atherinopsidae) coexisting in the southwestern Atlantic Ocean
TLDR
The hard structures used in this study proved to be a useful tool for the correct identification of the atherinids found in the diet of piscivorous species from the southwestern Atlantic Ocean.
DIET OF TADPOLES FROM A POND IN IGUAZU NATIONAL PARK, ARGENTINA
TLDR
Analizar el contenido intestinal de diferentes especies of larvas de larvas que conviven en el mismo cuerpo de agua durante las estaciones de maxima y minima precipitacion pluvial para incrementar el conocimiento oficial de la historia natural de estas larvas.
Internal Oral Morphology of Tadpoles of Dermatonotus muelleri and Elachistocleis bicolor
TLDR
It is suggested that the oral flaps and the roof papillae play a significant role in the capture of food particles by establishing the inflow of "alimentary water", and aggregating food particles and mucus inside the buccopharyngeal cavity.
ON THE DEXTRAL CONFIGURATION OF THE ANURAN LARVAL VENT TUBE
TLDR
The morphology and microanatomy of the dextral vent tube configuration were studied in various species classified into three categories: (1) marginal external tube, (2) nonmarginal externaltube, and (3) without external vent tube, but with an external aperture in the posterior wall of the body.
Euglenoids living in the intestines of microhylid tadpoles of Argentina
Dans le contenu intestinal de tetards de Dermatonotus muelleri et de Elachistocleis bicolor provenant de divers environnements aquatiques, nous avons trouve une grande quantite d'euglenoides
Origin and development of the vent tube in two species of the genus Bufo
TLDR
The vent tubes of different types of larvae in stages 25-26, and with medial configuration, showed similar structural organization, among them and with the bufonids examined in this study; however, two layers of epithelial tissue separated by mesenchyme were always present.
