Diver waves to humpback whales... and GETS A WAVE IN RETURN!

Swimming alongside humpback whales has got to be a bone-chilling experience, but one that is equally soothing at the same time.

In this mesmerizing clip, Rachel Moore is seen documenting her underwater adventure and close encounter with a couple of humpback whales.

The filmer waves to the big-winged cuties, and surprisingly gets a wave in return from one of them!

"Swimming with humpback whales in French Polynesia," Rachel said. "I always wave to the whales and sometimes, they wave back!"
