Bunbury Dolphin Centre

This was our last stop before Perth, the Dolphin Centre.


Jacob was interested in this Octopus after watching the feeding.


Octopus have the ability to camouflage because they have specialised skin cells. These cells are called chromatophores and can change the octopus colour and appearance within microseconds. Each cell contains yellow, orange, red, brown or black pigment.

I found a baby mummified turtle on the specimen table. Maybe he didn’t make it into the water.


So many details for such a small creature; even his flipper.


This tank had the Port Jackson Shark. We got to see him being fed.


I love Port Jackson Sharks. They are very interesting sharks. They are oviparous, which means egg laying. The egg case is a tough brown spiral shape. When the egg is laid it’s quite soft and is wedged into a rock crevice using the sharks mouth. Eventually it hardens and 12 months later a shark pup hatches out. Port Jackson Sharks are harmless but have a venomous spine in front of each dorsal fin. You can see it in this photo.
