Metazoan endoparasites of Serrasalmus marginatus (Characiformes: Serrasalminae) in the Negro River, Pantanal, Brazil [PDF]
Brazilian Journal of Veterinary Parasitology, 2011 In order to inventory the metazoan endoparasites of Serrasalmus marginatus, 91 specimens were examined. They were captured in the Negro River in Pantanal wetland, State of Mato Grosso do Sul, Central-Western Brazil, from October 2007 to August 2008.

Connections of the olfactory bulb in the piranha (Serrasalmus nattereri)
Cell and Tissue Research, 1981The connections of the olfactory bulb were studied in the piranha using the Nauta and horseradish-peroxidase methods. Three olfactory tracts project to seven terminal fields in the telencephalon and one in the diencephalon, all of them bilaterally. The contralateral olfactory bulb also receives a small input.

Afferent connections of the optic tectum in the piranha (Serrasalmus nattereri)
Cell and Tissue Research, 1983Injections of horseradish peroxidase into the optic tectum of the piranha resulted in retrograde transport to the following structures bilaterally: the central telencephalic nucleus, four hypothalamic nuclei, the caudal part of the dorsomedial optic nucleus, the ventral nucleus of the torus semicircularis, the torus longitudinalis, the perilemniscal ...

Eye movements evoked from telencephalic stimulations in the piranha (Serrasalmus nattereri)
Comparative Biochemistry and Physiology Part A: Physiology, 1985The telencephalon of spinally transsected, unanesthetized piranhas was systematically stimulated with microelectrodes to scan for eye movement inducing (EMI) sites which were then identified by histological means. EMI sites were found clustered in several distinct central and medial telencephalic areas.

With the intent to provide additional information on the reproductive biology of the ostariophysian fish, the oocyte development in Serrasalmus maculatus is here described under light and electron microscopy by using some cytochemical methods. Our results are discussed considering the cellular processes that drive the oocyte development and comparing ...

Double cone mosaic pattern in the retina of larval and adult piranha,Serrasalmus spilopleura
Experientia, 1992The mosaic pattern of double cones of retinas in larval and adult piranha,Serrasalmus spilopleura, was examined. Samples from two habitats in the same reservoir, characterized by different light conditions, were examined. The same square pattern was found in all sampled retinas indicating that, for this species, there is no apparent relation between ...

Invasion dynamics of the white piranha (Serrasalmus brandtii) in a Neotropical river basin
Biological Invasions, 2019Clarifying the intricate history of unrecorded fish invasions represents an important step in understanding the invasion process. Here, we elucidate the invasion of a Neotropical river basin in Southeastern Brazil by a very efficient predator, the white piranha (Serrasalmus brandtii).
