Monophyly of the Agoniatinae (Characiformes: Characidae)
Zootaxa, 2013The Characidae is the most diverse family of Neotropical fishes, currently encompassing more than one thousand valid spe-cies. Some subgroups within this family still lack phylogenetic definitions, being diagnosed on the basis of combination of characters, a common procedure in pre-cladistic studies. Agoniatinae, currently composed by two valid species,

Characidae The largest characiform family, characids are abundant in several environments throughout the Neotropical region. Because of their heterogeneous nature, the species are arranged in several subfamilies in addition to many genera incertae sedis, following Lima et al. (2003). In the present study, the characids are presented jointly.

Observations on tooth replacement in piranhas (Characidae)
Archives of Oral Biology, 1975Abstract Skeletal and preserved material from 15 piranha fish ( Characidae ) were examined radiographically and the heads of a further three specimens of body length 2.5–4.0 cm examined histologically. Such material revealed a close correlation in the stage of development between upper and lower dentitions on the same side of the jaws but the stage ...

The dynamics of parental care of Copeina arnoldi (pisces, characidae)
Behavioral Biology, 1976The parental behavior of 10 isolated male Copeina arnoldi with single spawns was monitored throughout the parental cycle. Parental splashing frequency decreased daily after spawning. Daily mean splashing frequencies observed ranged from 38.5 to 0.2 splashes per hour. No diurnal cycle of parental splashing could be discerned. Bouts of parental splashing
