阿根廷平囊鯰

Raphidascaroides Infection 1. Parasitic infestations (protozoa, worms, etc.)

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Analsoft rays: 10 - 11

Lives on the bottom and feeds on mollusks, crustaceans, and organic debris. Frequently occurs on sandy bottoms. Often escapes into the sediment where it hides 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). The study indicated that the cleaning behavior is probably restricted to the juvenile phase. The species shifts its diet as it grows, facultative cleaner (Ref. 50806).

Platydoras costatus, the Raphael catfish, is a species of thorny catfish native to rivers in Suriname and French Guiana. It was long confused with other species in the genus Platydoras, especially the more widespread "true" striped Raphael catfish (P. armatulus). P. costatus grows to a length of 24 cm (9.4 in) SL, and unlike P. armatulus the light stripe along the body of P. costatus does not extend onto the head. This fish is a minor component of local fisheries and is also found in the aquarium trade.
