Zusammenfassung:A mass stranding of A. nodosa was registered along more than 250 km of the Uruguayan coast between January and April 2004. Such unusual event was associated with singular oceanographic and meteorological conditions that advected oceanic warm waters toward the shore, reaching inside the Rio de la Plata estuary. This is the first record of a mass stranding of argonautid cephalopods in the southwestern Atlantic Ocean.Original Abstract: Un varamiento masivo de A. nodosa fue registrado a lo largo de 250 km de la costa uruguaya entre enero y abril del 2004. Este evento inusual estuvo asociado con condiciones oceanograficas y meteorologicas singulares que advectaron aguas oceanicas calidas hacia la costa, penetrando incluso en el estuario del Rio de la Plata. Este es el primer registro de un varamiento masivo de cefalopodos argonautidos en el Atlantico sudoeste.
