Potamotrygon cf. falkneri

18. March 2009

Currently we have a great selection of wonderful river stingrays from Paraguay belonging to that species in stock. As in all river stingray species, each individual has its own colour pattern, which differs clearly from all other congeneers. This is one of the reasons why species can only be distinguished with great difficulties in Potamotrygon. Moreover there is strong evidence (DNA-analyzes, colouration) that the species hybridize in nature .

Potamotrygon cf. falkneri belongs to the big species of river stingrays. Specimens of more than 60 cm disc width are known. It is very interesting that there exist dwarf males that reach sexual maturity at only 20 cm disc width while other males are unripe even at 40 cm disc width. Sexual maturity can easily be recognized by the size of the sexual organs, the so-called claspers.

For our customers: the animals have code 282955 on our stocklist. Please note that we exclusively supply to the wholesale market.
