A dozen humpback whales were captured emergng from the water during a feeding frenzy in Alaska.
The magnificent creatures broke the surface of the sea to swallow large pockets of herring.
Jon Cornforth, 42, from Seattle, took the remarkable images during a tour of Alaska's Inside Passage in August this year.
While sailing on the boat Jon came across the herd of humpbacks working together to feed.
The pod worked as a team to dive beneath a school of herring and force the meal towards the surface - making sounds and blowing a stream of bubbles towards the fish. Words: Barcroft
As they rise the whales swim to the surface with their mouthes open to collect the herring - breaking head first into the air in a practice known as bubble feeding.
Jon said: "I have observed humpbacks repetitively breach 25 or more times over the course of an hour, but most often they breach a few times and then stop.
"The exciting thing about photographing the whales bubble-feeding is that they will feed every five to ten minutes for hours at a time, so they are constantly on the surface."
"They are unpredictable in their direction and behaviors, so I have to be very patient until they do something interesting or come surprisingly close.
