Whale hello there!

A group of tourists were lucky enough to capture the moment a herd of whales launched into a feeding frenzy in Juneau, Alaska.

As the whales compete for food in the water, a flock of opportune seagulls can be seen flying above them, waiting to pounce for scraps.

A delighted tourist watching the whales turns to face the camera with a big grin on her face.

'Oh my God, it's so cool,' she says.

The whales breache in the water during the feeding session. The mammals also spouted in the footage, which was filmed in August.

'They can swallow like 10,000 gallons, I think, and then they just, like, spit out all the water,' an off-camera voice says.

At one point, a whale close to the tourists' boat spouted noisily in the water.

The woman commented: 'Holy s***!'

Juneau Whale Watch, which offers whale watching tours, says on its website: 'So when is the best time to see whales in Juneau? Southeast Alaska is renowned for numerous sightings of humpback whales.

'And sometimes orcas (killer whales) as well. Humpback whales are usually seen during the months of May right through to the back end of September.'

According to NOAA, humpback whales weigh '25-40 tons (50,000-80,000 pounds; 22,000-36,000 kg),' and are as long as 'up to 60 feet (18 m), with females larger than males'.
