Common Bottlenose Dolphin

this site is good see if you can find the dolphin you saw here http://www.whales.org.au/discover/dolphins/index.html

i doubt that that's a bottlenose dolphin, if you look carefully at the dorsal fin you'll see it's much too curved http://www.google.co.za/imgres?imgurl=http://1.bp.blogspot.com/-SPxk5slhtcI/Td0hN0fe3MI/AAAAAAAAAOI/p7zv24UcK4I/s1600/066-10L_L_100903_020_pedryn_DFE_051_1.jpg&imgrefurl=http://seawatchfoundation.blogspot.com/2011/05/fingerprinting-bottlenose-dolphins.html&h=615&w=923&sz=141&tbnid=7JniqO4cn1x-cM:&tbnh=90&tbnw=135&zoom=1&usg=__ScSXvzOahU3gP5_ln14ZR1vqOGI=&docid=ehiOHgzm1P8tHM&sa=X&ei=wZmUUe27LdO3hAfm84C4Dw&ved=0CDQQ9QEwAg&dur=325

The website has a really good picture of the belly of the dolphin. Verify this is as you saw. http://en.wikipedia.org/wiki/Common_Bottlenose_Dolphin
