January 4, 2018 — Frigid temperatures may have transformed the waters off Cape Cod to ice, but it turns out the recent cold snap is not literally just freezing sharks to death.
It may, however, be contributing to the ocean predators getting trapped in Cape Cod Bay.
Greg Skomal, the senior fisheries scientist for the state Department of Fish and Game who leads the Massachusetts Shark Research program, said the thresher sharks — like the four that have been found dead in Wellfleet and Orleans in recent days — are dying as they attempt to swim to warmer southern waters but are getting stranded in shallow waters in Cape Cod Bay.
“The rapid cooling associated with this cold snap and water temps is forcing the sharks to move south at a faster pace, and the landmass of Cape Cod is contributing to them getting stranded in shallow water,” said Skomal, adding that the exact cause of the sharks’ deaths remains hypothetical at this time.
Cape Cod, with its shape of an outstretched human arm that hooks at Provincetown, can act as a natural trap for animals trying to move south quickly, and most shark species need to be continually moving in order to breathe effectively, he said.
