Etymology: Platydoras: Greek, platys = flat + Greek, doras = skin (Ref. 45335).
More on author: Linnaeus.
Taxonomic Remarks
Widespread and geographically variable species. Le Bail et al. (2000) recognized two distinct species of Platydoras in the Rio Maroni; however, their use of available names is questionable. Accurate determination of available names and the likely discovery of undescribed species await thorough revision.

Dorsale stekels (totaal) : 1; Dorsale zachte stralen (totaal) : 6; Anale zachte stralen: 10 - 11.
Body shape (shape guide): elongated.
Adults live on the bottom and feeds on mollusks, crustaceans, and organic debris. They occur on sandy bottoms and often escape into the sediment where they hide among the anfractuosities of the submerged stocks (Ref. 35381). A juvenile in a stream of the rio Araguaia was recorded to clean the piscivorous characin Hoplias cf. malabaricus (Ref. 50806).
