French photographer Greg Lecoeur also snapped this mesmerising image of a pod of pilot whales circling beneath the surface

Alejandro Prieto from Mexico, who took this amazing picture, said: 'Returning from a dive with bull sharks in Playa del Carmen in Mexico, I saw a beautiful flock of seagulls flying very low over a crowded beach. They usually fly low over the people looking for food. This behaviour allowed me to try to shoot them from beneath the water. With this photograph I want to show that ordinary subjects can become extraordinary depending on the perspective you see them'
