Sydney Marine Life

Sydney Marine Life
Australia offers some fantastic scuba diving with a broad range of marine life and Sydney as the gateway to Australia offers diving unequalled by any large city. A recent study revealed that Sydney has more marine species than any other harbour in the world. Some 600 marine animals have already been identified and we can be sure that there are more to be found. One of the great attractions of diving around Sydney is its abundant marine life. The following are some examples of the more interesting marine creatures which can be found around Sydney.

The Australian Fur Seal, Arctocephalus pusillus doriferus is the largest of all the fur seals, weighing around 200 - 300kg.
The main sea urchin we see around Sydney is the Black Sea Urchin (Centrostephanus rodgersii). Although there are other species that live in our waters I will mainly focus on the Black Sea Urchin.
Most divers would already know the Eastern Blue Groper. The Blue Groper is the largest reef and most well known fish in the waters around Sydney.
The Giant Cuttlefish is generally found hiding in caves and crevices and is generally very curious when approached by divers. When divers approach they will often come forward to investigate and they appear to like divers objects that have bright fluorescent colours (such as green and pink). Giant Cuttlefish have been seen following divers that wear brightly coloured fins.

Eastern Blue Devil Fish are solitary creatures that usually live alone in caves or crevices during the day; it can sometimes be seen out roaming the reef at night. Usually they appear shy to divers, as they do not swim away fleeing when discovered, but tend to move to the very back of a cave or crevice to remain out of site.
