Última Comparative gross encephalon morphology in Callichthyidae (Teleostei: Ostariophysi: Siluriformes) Neotropical Ichthyology Pupo,Fabio M.; Britto,Marcelo R.. ABSTRACT Callichthyidae comprises the subfamilies Callichthyinae and Corydoradinae, both of which are morphologically distinct and monophyletic. Although there is consensus regarding the monophyly of the family, the relationships of about 80% of its species, currently included in the genus Corydoras, remain poorly known. Despite the vast amount of osteological information for Teleostei, knowledge regarding the phylogenetic implications of encephalon anatomy is sparse and represents a poorly explored source of potential characters. The present study aims to describe the encephalon morphology in members of the Callichthyidae in order to propose new characters that may help address phylogenetic questions regarding this group. In addition to representatives of... Tipo: Info:eu-repo/semantics/article Palavras-chave: Brain; Comparative Morphology; Corydoras; Loricarioidea; Systematics. Ano: 2018 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252018000400201 Gross morphology of the brain of Pseudopimelodus bufonius (Valenciennes, 1840) (Siluriformes: Pseudopimelodidae) Neotropical Ichthyology Abrahão,Vitor Pimenta; Shibatta,Oscar Akio. The gross morphology of the brain of the pseudopimelodid Pseudopimelodus bufonius is described and compared with congeners. Observations were made on removed brains after elimination of bones from the top of the skull and severing of the cranial nerves and the spinal cord. Nine morphometric characters associated with the major subdivisions of the brain were identified, seven of which revealed significant differences among the species examined. The corpus cerebelli in all examined species of the genus is the largest structure of the brain. The behavior of the species of Pseudopimelodus is still unknown, but in other teleosts that condition is typically correlated with a higher degree of motor coordination. Relative size proportions of the tectum opticum,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Behavior; Catfishes; Comparative Morphology; Neotropical fishes; Neuroanatomy.
