(Seattle, WA)  --  Researchers say they have no plans to remove a now-rotting orca carcass from her mourning mother.  The Center for Whale Research confirms they spotted the orca J35, also known as Tahlequah, yesterday carrying her dead calf for the 17th straight day following his death just half an hour after being born late last month.  Researchers say removing the dead calf is not an option due to the tight bond between Tahlequah and her child, dead or alive.
