Photographer's Note

Rorquals feed on plankton by a technique called lunge feeding. Lunge feeding could be regarded as a kind of inverted suction feeding, during which a whale takes a huge gulp of water, which is then filtered through the baleen. Biomechanically this is a unique and extreme feeding method, for which the animal at first must accelerate to gain enough momentum to fold its elastic throat (buccal cavity) around the volume of water to be swallowed. Subsequently, the water flows back through the baleen, keeping back the food particles. The highly elastic and muscular buccal rills are a specialized adaptation to this feeding mode.

This was taken off of Cape Cod. These Humpback Whales tend to team up feeding like this as the Seagulls try to steal the food right out of the whales mouths.
