By The Number: Right whales

160

That’s roughly how many North Atlantic right whales were spotted in Cape Cod Bay Sunday , according a National Oceanic and Atmospheric Administration official. The whales, which return annually to Cape Cod waters to feed and mate, are among the world’s most endangered species, with scientists estimating that only 411 are alive today. Video footage captured by a drone Sunday shows one joyous right whale doing a happy twirl in the blue-green waters just off Provincetown.
