Humpback whales with young calf in Tongan waters

These stunning images were captured by a British underwater photographer as he swam with a pod of humpback whales with a young calf.

The beautiful creatures curiously approached Brit snapper Steve Woods after he plunged into the sea off the coast of Tonga in the South Pacific Ocean.

The marine mammals can be seen approaching the camera before slapping and even waving their tail fins in an apparent attempt to interact.
