What was that sound? Pec Slapping Humpback Whales in Jervis Bay.

What was that sound? Pec Slapping Humpback Whales in Jervis Bay.

Have you heard a Humpback’s ‘pec slap’?

Where a whale ‘slaps’ its pectoral fin on the surface of the water. These fins can be up to 6ft long! Often the whale is resting on it’s back or side exposing its large white underside, which is quite striking against the deep blue sea – or our beautiful Jervis Bay.

We most frequently observe this behaviour on the Southern Migration and see Humpback Calves testing out this skill for the first time!

I sometimes describe it as the “thhaawopp!” sound a foam body board makes when it is slapped on the water at the beach.

& have heard customers say it sounds like a crocodile snapping it’s mouth..

A finding from recent research suggests ‘pec slapping’ could be more commonly used as a form of communication when the wind picks up as vocal sounds become less audible….

🤔 How interesting!

"HOWEVER, the staff were AMAZING!!!"

Didn't see any whales or Dolphins, or any sea life at all actually and it was cold and rainy with swells that reached 3 metres which resulted in more than a few people with their head in the sick bag the entire trip..... HOWEVER, the staff were AMAZING!!! Jane was so positive, bubbly and hilarious as well as caring and genuine. The staff can't control the weather, and they certainly can't control when the whales will show up but they handled it so well. We can't wait to come back just to hear Jane's laugh!
