MIDDLETOWN, N.J. (AP) -- Since winter closed in on a family of dolphins that had been living in two New Jersey rivers, many observers felt the animals were living on a prayer.

On Saturday, the body of another dead dolphin was spotted in the Navesink River just outside the Middletown home of rocker Jon Bon Jovi.

If it's confirmed to be part of the group of 16 dolphins that had spent half of last year in the Shrewsbury and Navesink rivers, it would be the sixth to have died.

The dead dolphin is the third to surface in the past two weeks. DNA test results are pending on the previous two to determine whether they were part of the pod that created such a stir last year.
