Broome, Western Australia, is renowned for its incredible whale watching experiences. However, the region’s marine ecosystem is a treasure trove of biodiversity, teeming with life beyond the majestic humpbacks. Let’s delve into the underwater world of Broome and explore the fascinating creatures that call these waters home.

Dolphins: Playful Companions of the Sea

Roebuck Bay is a dynamic environment that supports a diverse dolphin community.

• Snubfin Dolphins: Broome boasts a significant population of snubfin dolphins, a rare and elusive species endemic to northern Australia. These small, agile dolphins are known for their playful behavior and acrobatic displays, often seen foraging in shallow waters and around mangroves.
• Bottlenose Dolphins: Common residents of Roebuck Bay, bottlenose dolphins are highly social and often seen traveling in pods. They are frequently observed feeding and socializing in the deeper channels and around the edges of the bay.
• Indo-Pacific Humpback Dolphins: These smaller, more slender dolphins are occasionally sighted in Roebuck Bay. They are typically found in coastal waters and estuaries.

At times, these intelligent creatures accompany whale watching boats, showcasing their acrobatic feats and curious nature.

Turtles: Ancient Guardians of the Ocean

Roebuck Bay provides important habitat for several species of sea turtles.

• Flatback Turtles: This species is endemic to Australia and is a common sight in Roebuck Bay. They are known for their distinctive flat shells and their tendency to nest on beaches at night.

• Hawksbill Turtles: These critically endangered turtles are renowned for their beautiful, intricately patterned shells. They are occasional visitors to Roebuck Bay, primarily foraging for sponges.

Dugongs: Gentle Giants of the Seagrass Meadows

Roebuck Bay is renowned for its extensive seagrass meadows, providing vital habitat for dugongs. These gentle giants, also known as “sea cows,” are herbivores that graze on seagrass, playing a crucial role in maintaining the health of the bay’s ecosystem.

• Endangered Species: Dugongs are a vulnerable species, facing threats from habitat loss, entanglement in fishing gear, and boat strikes.
• Roebuck Bay’s Importance: The bay’s healthy seagrass meadows are crucial for the survival of the dugong population, making it a vital area for their conservation.
• Observing Dugongs: While sightings can be unpredictable, encountering a dugong while exploring Roebuck Bay is a truly special and memorable experience.

A Rich Tapestry of Marine Life

Beyond these iconic species, Roebuck Bay is home to a vibrant tapestry of marine life.

Roebuck Bay Marine Park: A Protected Haven

Roebuck Bay, a vast and dynamic ecosystem covering approximately 550 square kilometers, is shaped by significant tidal fluctuations. Tides can range from minimal to over 10 meters during spring tides, influencing the distribution of marine life and creating extensive intertidal mudflats that support a diverse range of species.

Roebuck Bay, a significant portion of which is designated as a Marine Park, plays a vital role in protecting this diverse ecosystem. This Marine Park aims to conserve the unique marine life within its boundaries, including seagrass meadows, mangrove forests, and the numerous species that depend on them.

Migratory Shorebirds: A Global Phenomenon

Roebuck Bay is a critical stopover point for millions of migratory shorebirds during their annual journeys. These long-distance travelers utilize the bay’s extensive mudflats and tidal areas for feeding and resting.

• Globally Significant: Roebuck Bay is internationally recognized as a site of global importance for shorebirds, supporting a wide variety of species, including red knots, bar-tailed godwits, and curlews.
