Record of cleaning behavior by Platydoras costatus (Siluriformes: Doradidae) in the Amazon Basin, Brazil

Abstract

Records of cleaning symbiosis between freshwater fish are scarce. Here we report on juvenile catfish, Platydoras costatus, cleaning the piscivorous characin Hoplias cf. malabaricus in a stream of the rio Araguaia drainage in the Brazilian Amazon. The scarcity of records on cleaning behavior in freshwater systems seems to be in part a consequence of the few observational studies under natural conditions in the Neotropics. Otherwise, the rareness of this behavior in freshwaters is possibly related to the short evolutionary time available to the fish fauna to develop these complex interactions, when compared to the ocean environment.<br>Registros de simbiose de limpeza entre peixes dulcícolas são raros. No presente trabalho registramos um juvenil de Platydoras costatus, limpando uma traíra, Hoplias cf. malabaricus em um riacho do rio Araguaia, Bacia Amazônica. A escassez de registros de comportamento de limpeza em peixes de água doce parece ser uma conseqüência dos poucos estudos subaquáticos nos Neotrópicos. Por outro lado, a raridade deste comportamento em ambientes dulcícolas está possivelmente relacionada ao curto tempo evolutivo disponível para o desenvolvimento de interações complexas, quando comparada ao ambiente marinho

Phylogenetic relationships of the South American Doradoidea (Ostariophysi: Siluriformes)

“…3). This color pattern is related to the elaborate behavior of cleaning fishes in Platydoras armatulus (Carvalho et al, 2003), and possibly also in the others. All other examined species have pale or brown background color, uniform or covered by dark or pale (faint white in life) blotches and/or stripes.…”

Cleaner fishes and shrimp diversity and a re‐evaluation of cleaning symbioses

“…The concept of a universal colour guild for cleaners was not conclusively supported by the analyses of Côté (2000), and whether cleaners use colour to signal cleaning services remains untested. Although longitudinal striping is a common feature of dedicated cleaner fishes (Côté, 2000) and is now demonstrated for a facultative cleaner (see Carvalho, Arruda, & Zuanon, 2003), all considerations of cleaner coloration or patterning made to date have been limited to the visible light spectrum. Ultraviolet light has a fundamental function in the mutualism between angiosperms and their pollinators (Papiorek et al, 2016), and ultraviolet reflective body patterns have been demonstrated as a means of communication in fishes that can visualize ultraviolet (Siebeck, Parker, Sprenger, Mäthger, & Wallis, 2010).…”

Nuclear-follower foraging associations among Characiformes fishes and Potamotrygonidae rays in clean waters environments of Teles Pires and Xingu rivers basins, Midwest Brazil

“…The following behavior comprises one or a group of individuals that excavate or disturb the substrate while foraging, and one or more opportunistic species that capitalize on the small organisms and other food types displaced by the foraging activity of the former (Strand 1988, Lukoschek & McCormick 2000. This type of interespecific interaction has been widely described to teleost fishes in marine environments (see Strand (1988) and Sazima et al (2006) for overviews), although a few instances are reported from neotropical freshwater habitats that provide conditions for underwater observations (Sazima 1986, Baker & Foster 1994, Casatti & Castro 1998, Sabino & Zuanon 1998, Sabino 1999, Carvalho et al 2003a, Garrone Neto & Sazima 2009a, Leitão et al 2007, Teresa & Carvalho 2008, Teresa et al 2011.…”
