There are two main species of dolphins found in South Australian waters; the Bottlenose Dolphin and the Common Dolphin.
Common Dolphins are dark grey on top with a yellow/ cream hourglass pattern on their sides and a white/cream belly.
Common Dolphins are generally found in deeper waters out in the gulf; however on the evening of October 29th 2012 we had our first recorded sighting of a Common Dolphin exploring the Port River. The Common visited for a few hours and swam all the way to the end of the river. It was certainly an amazing site to see. http://www.environment.sa.gov.au/Home/Full_newsevents_listing/News_Events_Listing/121031-common-dolphin
Common dolphins are often seen in large pods. They are very social and very energetic. There are two main species of Common Dolphin the Short-beaked and the long beaked. Common dolphins can be found in oceans around the globe.
