Unique Marine Life

The Arches Marine Sanctuary is a biodiversity hotspot, a window into the underwater world of the Bass Strait. Its deeper waters and rocky formations create a perfect environment for marine life from tiny invertebrates to big predatory fish. The sanctuary is home to many species that thrive in the cool waters, several of which are rare or endangered.
The underwater arches and shaded undersides of the rocky reefs provide a home and breeding ground for marine organisms. This unique habitat supports diverse ecosystems with species found only in this part of the Southern Ocean. The sanctuary’s conservation commitment means the ecosystems remain healthy and thriving, so you can see marine life in its purest form.

Species to See

When you visit The Arches Marine Sanctuary, you will see an amazing array of marine life. Some of the highlights are the weedy seadragon, Victoria’s marine emblem, with its striking looks and amazing camouflage. Blue gropers, stingrays and various types of wrasse and snappers also call the sanctuary home.
Not just fish, the rock pools and coastal cliffs are also home to Australian fur seals who often bask on the nearby rocky outcrops. They sometimes swim with divers, adding an extra level of excitement to your underwater adventure. You might also see dolphins cruising through the waves or even humpback whales during their migration season. The sanctuary’s biodiversity extends beyond the water, and coastal birds like cormorants, gannets, and shearwaters nest in the cliffs.
