Hi Everyone,

It has been another great month.

The Adelaide Dolphin Sanctuary Action Group and Whale and Dolphin Conservation Volunteers continue to do a fantastic job working on many different projects.

I was very fortunate to have a wonderful holiday in Hawaii visiting the Spinner Dolphins.

Spinner dolphins are named after the incredible spins they do as they leap into the air. They inhabit tropical waters and are much smaller than the bottlenose dolphins at Port Adelaide.

Sadly they face many of the same threats as our dolphins including harassment from people.

The Port River dolphins have also been active.

Wave and Bianca have been delighting onlookers with their tail walking antics.

To see footage of the Port River dolphins tail walking and to learn more about this incredible behaviour please view the video here.

Doc has been particularly playful and has regularly been seen spy hopping and leaping out of the water.

Doc is now seven months old and is carrying out many of the different behaviours he has learnt from his mum, Bianca, and some of the other resident dolphins.

Lunar, Marianna and Star have also been energetic and have been surfing and riding the bow waves in front of both the Tug boats and the Dolphin Explorer.

Also this month we have seen Captain Hook, Mouse, Bronny, Sparkle, Gem, Crystal, Hope, Tallula, Bubbles, Big Fold, Ryan and Unhap.

Please look out for the next Dolphin Diary on Friday August 2nd.

Best Wishes

Marianna
