Anatomia visceral comparada de seis espécies de Amphisbaenidae (Squamata: Amphisbaenia) Rev. Bras. Zool.
Navega-Gonçalves,Maria Eliana C..
Visceral anatomy of amphisbaenids Amphisbaena vermicularis Wagler, 1824; Anops kingii Bell, 1833; Aulura anomala Barbour, 1914; Bronia bedai Vanzolini, 1991; Cercolophia cuiabana Strüssmann & Carvalho, 2001, and Leposternon microcephalum Wagler, 1824 were comparatively described and the size and the position of the organs in the pleuroperitoneal cavity was established in relation to the ventral scutellation. The main results were: the right lung presents different degrees of size reduction compared to the left lung, being conspicuous only in A. anomala, and L. microcephalum; the limit between small and large intestines is clear due to the presence of a caecum; the right lobe of the liver is larger than the left one, but its length varies within the...

Gross anatomy and histology of the alimentary system of Characidae (Teleostei: Ostariophysi: Characiformes) and potential phylogenetic information Neotropical Ichthyology
Alonso,Felipe; Mirande,Juan Marcos; Pandolfi,Matías.
A compared study of the morphology of the alimentary tract and liver of seven selected species corresponding to the main clades of the Characidae family is presented herein. Three new set of characters corresponding to 1) alimentary tract gross anatomy, 2) alimentary tract histology and 3) liver gross anatomy are evaluated as potential sources of data for future phylogenetic studies of the Characidae. Not considerable interspecific variation was observed at the histological level and therefore this source is not considered to be phylogenetically informative at the taxonomic level analyzed. In contrast, liver and alimentary tract gross anatomy presented important interspecific variation while a relatively homogenous intraspecific morphology was observed....
