Dolphin Diary: Unhap teaches calf Crystal his fishing technique Dolphin Diary June 6: Bubbles. Picture: Marianna Boorman Source: Supplied OUR Dolphin Diary writer Marianna Boorman has captured video footage of Port River dolphin Unhap teaching calf Crystal to fish. Read the Whale and Dolphin Conservation volunteer's latest diary and view her video and photos below: Hi Everyone, There has been lots of action this month from the Adelaide Dolphin Sanctuary Action Group and Whale and Dolphin Conservation volunteers as well as our wonderful dolphins. We have had several community events, presentations, land patrols, water patrols and a very successful training day for the volunteers. The dolphins have been just as active. Wave, one of our most energetic dolphins has been tail walking regularly. One evening in the space of 15 minutes she did an incredible 23 tail walks! There has been plenty of fishing action: Tallula has been avoiding the autumn leaves in the water as he races after and catches small garfish. Doc has started attempting to catch small fish. Doc is only 6 months old. It is usually about this age that they start to catch small fish although he still relies heavily on his mum's milk. One of the highlights of the month was seeing Unhap attempting to teach Crystal his unique fishing technique. This was very exciting site to see. To view footage of this and to learn about Unhap's unique fishing routine please click on the link below. It is great watching the different fishing techniques of our clever flippered friends; however this reminds us how important it is that we let wild dolphins be wild and that we let them catch their own fish. Despite the enormous efforts from the volunteers there are reports that people are still feeding and therefore endangering the life of one of our resident dolphins, Captain Hook. We will continue to work on this issue. We have also seen Bubbles, Lunar, Marianna, Mouse, Ripple, Ali, Ollie, Tiffany, Summer, Crystal and Hope. Please look out for the next Dolphin Diary on Friday, July 5. Best Wishes Marianna
