"The summer flounder – one of the most sought-after catches on the U.S. East Coast – is stirring up a climate change battle as it glides through the sand and grasses at the bottom of a warming North Atlantic.

Also known as "fluke," the flat, toothy fish is remarkable for its ability to change color to adapt to its surroundings, rendering it almost invisible to predators and prey.

Some scientists say in recent years the species has begun adapting in another way. As the Atlantic Ocean has warmed, they say, the fish have headed north."
