A huge shoal of sardines surrounded unsuspecting diver in seas off the Philippines allowing them to capture amazing picture of a breathtaking natural phenomenon.
The shoal was captured on camera by Nadya Kulagina on the last dive of her trip off the coast of the small Pescador Island which is close to Cebu in centre of the South East Asian country.
The magnificent spectacle, known as a sardine run, sees the silver fish swimming in tight formation to create a shimmering wall of fish during their annual migration to warmer waters.
