The group recently happened upon a Humpback whale who was nursing her calf for about a half hour south of the Penn Islands before the massive whale emerged from the water and flopped around.

The unsuspecting kayakers and boaters were stunned, thrilled and inspired to see the sights of the whale flipping around and started filming.

Wildcoast Adventures strung the footage together to make a clip of the awesome event.

Many times the whale got too close for comfort as breached in front of the surprised spectators.

While a breaching whale is quite a phenomenon to behold, it can be dangerous.

In September 2015, a humpback whale breached and landed on the kayak of a shocked California couple.

The kayakers were not injured and their experience was filmed by a nearby cruise ship.

This was one of the more dangerous situations that I've seen out here,” Captain Joe Sack of Sanctuary Cruises told “All of a sudden, this massive full-size whale does a full 180-degree breach and lands stomach first either right on top of or right next to two kayakers.”

The beast-like mammals can weigh up to 40 tons.
