Phoenix rises out of the waters east of Cape Cod, MA, in April 2003. The rough patches of skin (known as callosities) occur in unique patterns on all North Atlantic right whales and help researchers...
North Atlantic right whales and ocean-going vessels often cross paths. Researchers have worked to show the interactions between whales and ships in order to protect the whales from collision. More...
