Platydoras

Line catfish ( Platydoras armatulus )

Platydoras ( Gr. " platys " = wide Dora ) is a genus of freshwater fish from the family of catfishes ( Doradidae ). The genus is widespread in northern and central South America. The range extends from the basin of the Orinoco River, Guiana and the Amazon basin, the northeast of Brazil and the Rio Xingu to the Río Paraguay.

Features

Platydoras species, 15 to 24 cm long. Your body is plump and kaulquappenähnlich. The head large, broad and flattened about. The mouth is surrounded by three wide and Bartel pairs. The eye located in the front half of the head or the middle of the head is relatively large. The dorsal fin is high and triangular. My sting ray is serrated on its front edge and rear. The adipose fin is longer by a keel- like extension to the dorsal fin than the anal fin. The caudal peduncle is armored up and down through bone shields. The plates of the sides of the body are high, leaving only the dorsal region free. The large pectoral fins have a powerful sting ray and a locking hinge, with the spread pectoral fins can be fixed. The caudal fin is forked.
