(Seattle, WA)  --  Researchers continue to monitor a southern resident mother orca as she continues to cling to her dead child more than two weeks after its death.  The Seattle Times reports researchers spotted Orca J35, also known as Tahlequah, off the coast of the Olympic Peninsula yesterday.  She was carrying her dead calf for the 16th straight day since it died just after being born.  Meanwhile, researchers say they also spotted the starving three-and-a-half-year-old Orca J50 with Tahlequah's family yesterday.  NOAA has organized an unprecedented rescue plan to treat and possibly feed the young orca, but researchers had been searching for her since she disappeared for a few days last Friday.
