Shark Bay, a UNESCO World Heritage site in Western Australia, is a biodiversity hotspot that offers visitors a chance to experience some of the world’s most unique and rare species of plants and animals. This stunning coastal region is home to a variety of marine and terrestrial ecosystems, which together create a rich tapestry of life that has evolved to survive in its diverse habitats. Whether you’re exploring its underwater world, hiking through its national parks, or scanning the skies for rare birds, Shark Bay’s flora and fauna provide an unforgettable encounter with nature. Here’s what to look for while exploring the region’s unique wildlife.
Marine Life: A World Beneath the Surface
Shark Bay’s marine environment is one of the richest in the world, and the diversity of species found here is a key reason why the region earned its World Heritage status. The area’s extensive seagrass meadows, mangroves, and coral reefs provide a haven for marine life, with dolphins, dugongs, turtles, and an array of fish species calling the bay home.
1. Dugongs: The Gentle Giants of Shark Bay
Shark Bay is home to the largest population of dugongs in the world, with an estimated 10,000 dugongs feeding on the extensive seagrass beds. Often called "sea cows" for their slow, grazing behaviour, dugongs are a highlight for many visitors. These gentle giants are elusive but can be spotted on eco-tours and wildlife cruises, especially in areas like Big Lagoon and Monkey Mia.
Tip: Book a wildlife cruise from Monkey Mia or Denham for the best chance of seeing dugongs in their natural habitat.

2. Bottlenose Dolphins: The Stars of Monkey Mia
The bottlenose dolphins of Monkey Mia are world-famous for their friendly interactions with humans. For over 50 years, these dolphins have visited the shores of Monkey Mia, offering visitors an up-close wildlife experience. While the dolphins at Monkey Mia are the most well-known, dolphins can also be spotted throughout Shark Bay’s waters, often riding the waves or hunting for fish.
Tip: Visit Monkey Mia early in the morning for the dolphin feeding sessions, where you can observe these intelligent creatures in a regulated, sustainable environment.

3. Green and Loggerhead Turtles: Ocean Voyagers
Shark Bay is an important nesting and feeding ground for green turtles and loggerhead turtles, both of which are commonly seen in the bay’s waters. These ancient mariners can be spotted while snorkelling or during boat tours, gliding gracefully through the water or resting on the seafloor.
Tip: Turtle sightings are more common during nesting season, which occurs from November to January. Look for turtles in areas like Dirk Hartog Island and Big Lagoon.

4. Rays and Sharks: The Silent Predators
As its name suggests, Shark Bay is home to a variety of shark species, including whitetip and blacktip reef sharks, as well as the occasional tiger shark. These sharks play a vital role in maintaining the health of the marine ecosystem and can often be spotted from high vantage points like Eagle Bluff or while snorkelling and diving.
In addition to sharks, rays are commonly seen in Shark Bay’s shallow waters. Manta rays and eagle rays can be observed gliding through the water, especially around areas like Francois Peron National Park.
Tip: Eagle Bluffs boardwalk is one of the best places to spot sharks and rays from the shore, particularly during low tide when marine life is easier to see.

Terrestrial Wildlife: Life on the Land
Shark Bay’s terrestrial ecosystems are equally diverse, featuring coastal cliffs, salt flats, and arid shrublands that support a range of unique wildlife. Many of the species found in Shark Bay are rare or endangered, making the region a vital sanctuary for their protection.
5. Red and Western Grey Kangaroos
Kangaroos are a common sight in Shark Bay, particularly in Francois Peron National Park and the areas surrounding Denham. Both red kangaroos and western grey kangaroos thrive in the arid environment of the park. Visitors can often spot these iconic Australian animals grazing in the early morning or late afternoon, when the temperatures are cooler.
Tip: For the best chance of seeing kangaroos, visit Skipjack Point or explore the park’s walking trails during the cooler parts of the day.
6. Emus: Australia’s Tallest Birds
Emus, the tallest birds in Australia, are another frequent sight in Shark Bay. These large, flightless birds roam the parklands and plains, often in small family groups. Emus are curious animals and may approach visitors, especially in areas like Francois Peron National Park or along the tracks leading to Cape Peron.
Tip: Keep your distance when observing emus, as they can be unpredictable, especially when protecting their young.

7. Rare and Endangered Species: The Conservation Success Stories
Shark Bay has been a key player in the conservation of endangered species, with successful reintroduction programs for species like the rufa red-necked wallaby, Shark Bay mouse, and the western barred bandicoot. Francois Peron National Park and Dirk Hartog Island have been central to these efforts, providing secure habitats for these rare species to thrive.
These animals are shy and often elusive, but with patience and a bit of luck, visitors may catch a glimpse of them during early morning or evening wildlife drives in the national parks.
Tip: Join a guided wildlife tour in Francois Peron National Park or Dirk Hartog Island to learn more about the conservation programs and potentially spot some of these rare animals.
Birdwatching: A Haven for Avian Enthusiasts
Shark Bay’s diverse ecosystems make it a paradise for birdwatchers, with over 230 species of birds recorded in the area. Whether you’re scanning the skies for raptors or exploring the wetlands for migratory species, Shark Bay offers plenty of opportunities to observe Australia’s rich birdlife.
8. Pied Cormorants and Pelicans
The pied cormorant and Australian pelican are commonly seen along the coast, particularly around Monkey Mia and Big Lagoon. These large water birds are often spotted diving for fish or sunning themselves on the shores. Their graceful presence adds to the serenity of Shark Bay’s waters.

9. Ospreys and Sea Eagles
Birds of prey, including ospreys and white-bellied sea eagles, can often be seen soaring above Shark Bay’s coastlines, scanning the waters for fish. Look for their nests perched atop cliffs or in tall trees, particularly in Francois Peron National Park and around Eagle Bluff.
10. Migratory Shorebirds
Shark Bay’s wetlands, particularly around Hamelin Pool and Useless Loop, provide important habitat for migratory shorebirds. Species such as bar-tailed godwits, terns, and sandpipers travel thousands of kilometres to feed and breed in the nutrient-rich mudflats and shallows. The best time to see these birds is during the spring and summer months, when they arrive from their breeding grounds in the Northern Hemisphere.
Tip: Bring binoculars and a bird guide to make the most of your birdwatching experience, and explore the quieter, more remote areas for the best sightings.
Flora: Surviving in a Harsh Environment
Shark Bay’s plant life has evolved to thrive in its arid and often saline conditions. From hardy shrubs to vibrant wildflowers, the flora of Shark Bay plays a crucial role in maintaining the region’s fragile ecosystems.
11. Seagrass Meadows: A Vital Marine Habitat
One of Shark Bay’s most important ecosystems is its seagrass meadows, which cover an area of over 4,800 square kilometres, making them the largest in the world. These meadows provide food and shelter for a wide range of marine species, including dugongs, turtles, and fish. Shark Bay’s seagrass also plays a key role in carbon storage, helping to mitigate climate change by capturing large amounts of carbon dioxide.
12. Coastal Heath and Salt-Tolerant Shrubs
In the arid landscapes of Francois Peron National Park, you’ll find a variety of salt-tolerant shrubs and coastal heath. These hardy plants have adapted to Shark Bay’s harsh conditions, with many species flowering during the cooler months. Samphire and bluebush are common plants found in the region’s coastal salt flats, contributing to the area’s striking red, green, and blue hues.
Tip: Visit in spring (September to November) to see the wildflowers in bloom, creating a colourful contrast against Shark Bay’s sandy landscapes.
