HAWAII, PACIFIC OCEAN: EXPLODING into the air these pictures show the extraordinarily rare sight of two humpback whales breaching the ocean waves together. Scientists still do not fully understand why 40-tonne whales choose to throw themselves out of the water- but why two would decide to leap into the air at the same time is a greater mystery still. Other pictures captured by US wildlife photographer Jon Cornforth (43) off the coast of Hawaii show humpbacks breaching as they migrate towards their breeding grounds in the northern Pacific Ocean.
