Pod of right whales seen feeding off Cape

Boaters off Cape Cod are being urged to keep an eye out for North Atlantic right whales in waters close to shore after about 30 of the endangered cetaceans were spotted feeding off the coast of Provincetown. The state Division of Marine Fisheries issued a “high risk’’ advisory Wednesday because of the number of the whales, their proximity to shore, and the abundance of food drawing them to the area. “Dense concentrations of zooplankton at the surface and just below the surface are attracting the whales to this area,’’ the advisory said.
