We had a fantastic Marine Big 5 trip in the Dyer Island ecosystem today. The conditions were great for spotting wildlife, and it didn’t take us long after launching to find our first species. A group of bottlenose dolphins was close to land, just inshore from Dyer Island. It was a group of about 20 individuals, including at least 3 calves that we could count. They were travelling together in a tight group and were a real treat to see, especially because we hadn’t seen this species for several weeks. Our next Marine Big 5 member was the Southern right whale, just a bit offshore from Pearly beach. We encountered two individuals that were calmly laying at the surface and rolling around in the swell. Towards the end of this whale encounter we were even lucky that the whales decided to approach us do a bit of people watching. Next we headed towards the area of Dyer Island where we encountered Cape fur seals on Geyser rock, and on the other side of shark alley we saw some African penguins huddled together on Dyer Island. Finally, we went inshore towards the shallows where our sister company’s shark cage diving boat was operating. Here we were lucky to see four bronze whaler sharks, and some of us even got a glimpse of the shadow of a great white shark gliding past our boat.

What species did we see today?

At present there are two recognized species of bottlenose dolphin, and in some cases, both species can be found in the same area. The two species are the common bottlenose dolphin (Tursiops truncatus), and the Indo-Pacific bottlenose dolphin (T. aduncus). In addition, there is a great deal of variation in colouration, diet and behaviour. The difference between the common bottlenose and Indo-Pacific bottlenose dolphin are subtle, but the common bottlenose dolphin generally larger and more robust with a slight darker colouration.
