Texas dolphin die-off puzzles scientists - Yahoo! News: "'This is the calving season so we often have strandings at this time of the year. It's tough to be an air-breather born in the water,' said Dr. Daniel F. Cowan, professor of pathology at the University of Texas Medical Branch at Galveston and director of the Texas Marine Mammal Stranding Network.
'But over the last few weeks we have had about 3 to 4 times the usual mortality,' he told Reuters.
Most of the carcasses were in an advanced state of decomposition, suggesting that they were carried to Texas beaches from areas further off or up the shore."
Several of the dolphins which have washed up on shore have been young with umbilical cords still attached.
