Stranding survey as a framework to investigate rare cetacean records of the north and north-eastern Brazilian coasts
Marine mammal stranding events are used as an important tool for understanding cetacean biology worldwide. Nonetheless, there are vast gaps of knowledge to be filled in for a wide range of species. Reputable information is required regarding species from large baleen whales to sperm and beaked whale...
