The group of whale watchers were on a trip to San Ignacio Lagoon, in Baja California Peninsula, Mexico. As they were looking over the open ocean in anticipation of whales, one snuck up behind them in the water. Luckily, the group turned around at the last moment to catch the humpback whale before it disappeared.

A group of whale watchers nearly missed the moment of a lifetime when a sneaky whale popped up right behind their boat – as they looked in the opposite direction. The group were pictured waiting patiently with their cameras poised, but very nearly missed the spectacular encounter by looking the wrong way while the whale surfaced a matter of feet away from their boat.

Fortunately, the sightseers turned around in their boat just in the nick of time to spot the huge humpback whale, before she disappeared back into the ocean's depths, sparking scenes of celebration on the skiff. Photos taken from another vessel show the stealthy whale poking its rostrum out from beneath the water as the group face forward, pointing their cameras at the open ocean ahead of them in anticipation (pictured).

But before the creature could disappear into the sea again, the whale watchers spotted her at the last second, with a second photograph showing their jubilation at the close encounter (pictured).

One woman standing on the boat is shown throwing her arms into the air to celebrate, while the other sightseers sit open mouthed in surprise and click away on their cameras. The whale watchers' near-miss was captured by director and photographer, Eric J Smith during a trip to San Ignacio Lagoon, in Baja California Peninsula, Mexico.

Smith, a 49-year-old from Los Angeles, said the whale 'slowly and silently stuck her head high above the water to look around. I was in another panga a few dozen feet away and caught the moment right before everyone realized she was so close.'

'When everyone turned around, she quickly sank below the surface. Cheering and hysterical laughter ensued. 'Whale photography involves a lot of luck, but the key is to always be on alert and ready. On a whale watching voyage, it is easy to get complacent because there is a lot of waiting. It seems like the moment you let your guard down a spectacular breach occurs.'

They are known for breaching the surface, making them popular among whale watchers.

Like other large whales, humpbacks were once the target of the whaling industry which nearly hunted them until extinction. A worldwide moratorium in 1966 outlawed hunting, and their numbers have partially recovered since.
