Dolphins- Why do the Dolphins in Jervis Bay have marks all over them?

Dolphins- Why do the Dolphins in Jervis Bay have marks all over them?

When having encounters with dolphins we are often asked “what are all those marks and scratches on the dolphins from?”

The answer is surprising, these marks are actually ‘rake’ marks where dolphins have bitten each other and left a mark of their teeth.  We most commonly see these marks on the fins of dolphins as this is soft cartilage- although we do often see them on the upper body of the dolphins too.

These marks are often a result of dolphins contesting the hierarchy of the pod and asserting dominance and forming social bonds. Occasionally the rake marks can be helpful in identifying individuals, but they do gradually fade over time.

To check out the Dolphins for yourself, come out for a cruise with us!

"It was with out a doubt the best day we have had for years!"

My niece and I had a fantastic day both Dolphin and Whale watching. It was with out a doubt the best day we have had for years! We saw 2 types of dolphins, seals, fairy penguins and the majestic whales who seemed to be interacting with us for ages. The information given to us by the crew was spot on and very interesting. Thank you Paula and Johnny for an amazing day we will never forget. We were given a thorough safety run down, entertained, given history lessons, and given extra coats to block the wind. Can't wait to return and highly recommend it to everyone.
