GULFPORT, Miss. — Scientists say five dead baby dolphins have been found on two islands in the northern Gulf of Mexico, adding to what they say is an unusually high tally of dead dolphins in recent months off Mississippi and Alabama.
Researchers say they're seeking clues as to what caused the deaths. They report that 28 dolphins of all ages have been found dead in waters off the two states since the start of 2011, compared with 89 dead dolphins in all of 2010.
Moby Solangi, director of the nonprofit Institute for Marine Mammal Studies in Gulfport, says scientists have taken tissue samples in hopes of solving the mystery.
But scientists say they've ruled out possible effects from last summer's enormous oil rig spill off Louisiana.
