Area marine biologists remain stumped to explain why 50 dead leopard sharks were discovered washing up in Redwood Shores lagoons in April during the rainy spring season. The incident wasn't isolated to Redwood Shores. Hundreds of sharks began appearing in places as far north as Marin, and near Coyote Point in San Mateo.
Scientists determined that two specimens suffered inflammation, bleeding, lesions in the brain, and hemorrhaging from the skin, according to Redwood City spokesperson Malcolm Smith. Yet the cause of death is still to be determined.
