Amazon River’s mouth, the northernmost stranding site of humpback whales in Brazil

The current known distribution of humpback whales in Brazil is based on regular sightings and occasional strandings. Distribution of humpback whales in Brazil ranges from Rio Grande do Sul (34oS) in the south, to Para (00o42’S) in the north. We present the second case of a stranded humpback whale in the Amazon coast, and the northernmost stranding record in Brazil.
