Fish are within the Kingdom Animalia, in the Phylum Chordata, and the class of Osteichthyes. This website lists the fish seen in Sydney by its Order, its Family and finally the Species. This website focusses solely on fish that can be seen whilst shore diving or snorkelling in Sydney and I am sure there will be surprises with what this beautiful city has on offer!
The full classification used in this website is based upon that given in the book by Rudie H Kuiter "Coastal Fishes of South Eastern Australia". However, some families have been lumped together as the species within are so similar.
Along with the scientific latin classification this website also tries to present them by common names, however the common names differ from country to country and so caution should be taken.
