Marine Life: What You Can Expect to See

Australian Fur Seals

The Australian fur seals at Marengo Reefs are a highlight, they love to play and will entertain you. Found basking on the rocky islands or diving through the clear water, they are a symbol of the health of the marine ecosystem. Guided tours will get you up close and personal with these characters and learn about their habits and role in the ecosystem.

Fish Species

The sanctuary is full of colourful reef fish, the underwater landscape is dynamic. Schools of old wives, blue throated wrasse and banded morwong are common to see darting through the kelp forests and around soft corals. The mix of shallow water near the shore and deeper water further out means there is a wide range of species for both new and experienced divers.

Kelp Forests and Coral Gardens

The giant Bull Kelp and other kelp beds of Marengo Reefs are the base of the marine ecosystem. These underwater forests sway in the current and provide food and shelter for many marine species. Coral gardens with soft corals and sponge gardens add a splash of colour, making them an underwater paradise for snorkellers and divers. The reef life and these habitats mean biodiversity thrives.

Other Marine Life

Beyond seals and fish, Marengo Reefs is home to a whole other world of smaller creatures, such as nudibranchs, sea stars, and crustaceans. These can be found in the crevices of the rock formations or nestled in the seaweed gardens. Stingrays and even small sharks will occasionally swim through the deeper water, adding to the magic of this reef.
