In this paper we present a new record of sperm whale with notes on diet, age determination and a review of strandings along the continental argentine coast. A complete necropsy was made in the field, and morphometric data were taken. The specimen stranded was a mature male of 64+ years old. This is the oldest specimen determined for a sperm whale in the Southwest Atlantic coast. In the stomach contents a total of 302 cephalopod lower beaks were recovered. Cestodes were present in the blubber but parasites were not found in stomach and intestine contents. This stranding event constitutes the twelfth record for the argentine continental coast.
