http://www.upi.com/NewsTrack/Science/2008/04/13/right_whales_feeding_off_cape_cod/3041/PROVINCETOWN, Mass., April 13 (UPI) -- Observers say about one-fifth of the world's population of North Atlantic right whales is feeding off the coast of Massachusetts.
The Center for Coastal Studies in Provincetown, Mass., which has done aerial surveys of Stellwagen Bank, puts the number at 79, the Boston Globe reports. There are believed to be only 350 North Atlantic right whales remaining.
A system to monitor underwater sounds detected 219 right whale calls in one 24-hour period last week.
The reason for the gathering is copepods, minute crustaceans that are one of the right whales' main food sources.
