DNA scientists investigating new marine life migration patterns in the Atlantic Ocean surfaced the genetic traces of species far from their usual southern homes.

A species of ray—the Brazilian cownose ray, Rhinoptera brasiliensis, and the Gulf kingfish, Menticirrhus littoralis, have been turning up when the weather turns warm in New Jersey’s Barnegat Inlet, about a two hour drive south of New York City.

The ray has never before been recorded in the US north of the Gulf of Mexico; the perch-like Gulf kingfish has never before been recorded north of Chesapeake Bay, Virginia, about 250 miles (400 km) to the south. MORE
