Introduction to habitats in Port Phillip
Port Phillip Bay’s unique form creates a wide range of underwater habitats, homes to a rich diversity of marine plants and animals. Some of the bay’s rich marine life is visible from above water, in the form of seabirds seals and dolphins. However, few Victorians realise how spectacular the bay is underwater.
The rich marine life in Port Phillip Bay has attracted many marine biologists. Over the past two centuries hundreds of new species of animals and plants have been described from this one region. Creatures new to science are still being discovered today.
Dr. Mark Norman has been diving in this bay for 25 years, studying its fishes, octopuses and other marine animals.
"I think the most amazing thing about Port Phillip Bay is this huge array of marine life and habitat types in just one small area. It’s got everything. It’s got seagrass meadows, kelp forests, sponge gardens, sand plains and shear rock walls covered in anemones and corals. Elsewhere you’d have to travel hundreds of kilometres to find that sort of diversity."
