On the base of samples of congrid eels captured in the South Western Atlantic Ocean, between 34 degree S to 40 degree S and 30m to 400m depth, from research cruises, commercial fleet (low scale and coastal fishing) and specimens preserved in ichthyological collections, four species were determined: Ariosoma opistophthalmum, Conger orbignyanus, Bassanago albescens and Bassanago nielseni. The latter is the first record in the region. Diagnosis of taxa from Family Congridae to species is given. Morphology, reproduction, feeding and distribution of the fish species found from the region are compared and discussed, as well as those from other parts of the world. On the other hand, numerous samples of ichthyoplankton were obtained from research cruises carried out by both foreign and Argentinian research vessels in the 'Mar Argentino' and adjacent waters, in order to detect spawning and breeding areas. In the samples, leptocephali of the Order Anguilliformes and one unknown leptocephalus wer.....
