The Great Barrier Reef is one of the most incredible natural wonders on Earth. Stretching over 2,300 kilometers on Australia's Far North Queensland, it is the largest coral reef system in the world. But its size is not the only impressive thing about it. The reef is home to an astonishing number of species of fish and marine life, making it a biodiversity hotspot. As a world heritage listed area, it holds immense significance and attracts millions of tourists every year. However, this magnificent ecosystem is facing numerous threats that need urgent attention.
How big is the Great Barrier Reef?
The Great Barrier Reef is enormous, covering a total area of approximately 348,700 square kilometres. To put that into perspective, it is larger than the entire country of Italy! This vast expanse of coral reefs, islands, and cays is a sight to behold.
How many species call the Great Barrier Reef home?
The Great Barrier Reef is a haven for marine life, with an estimated 1,500 species of fish, 411 species of hard corals, and countless other organisms. It is like a bustling metropolis underwater, teeming with vibrant colors and fascinating creatures. From the iconic clownfish to the majestic manta rays, the reef is a treasure trove of biodiversity. If you look closely at our "Geo in The Great Barrier Reef" Luggage Cover you will see:
Golden AngelfishThe Golden Angelfish, also known as the Centropyge aurantia, is a stunning species found in the Great Barrier Reef. Its vibrant golden color and distinctive blue ring around its eye make it a true gem of the ocean. These angelfish primarily feed on sponges and algae, contributing to the reef's delicate ecosystem.
Yellow TangThe Yellow Tang, scientifically known as Zebrasoma flavescens, is a popular fish among snorkelers and divers. Its bright yellow colour and oval-shaped body make it easily recognisable. These fish have a herbivorous diet, feeding on algae, and play a crucial role in maintaining the reef's balance.
Royal Dottyback
The Royal Dottyback, or Pseudochromis paccagnellae, is a small but striking fish found in the Great Barrier Reef. Its vibrant purple and yellow colouration make it stand out among the coral. Interestingly, the Royal Dottyback is a carnivorous fish, preying on small crustaceans and other small fish.
Pacific Blue Tang SurgeonfishThe Pacific Blue Tang, scientifically known as Paracanthurus hepatus, primarily inhabits the tropical Indo-Pacific region, with a significant population concentrated around the extensive coral formations of the Great Barrier Reef. They are known for their vibrant electric blue colour and a distinctive royal blue and black pattern around their eyes and dorsal fin. The Pacific Blue Tang has a unique ability to undergo a dramatic colour change when transitioning from juvenile to adult stages, starting as bright yellow and adopting the iconic blue hue as they mature. You may recognise the Pacific Blue Tang from "Finding Nemo". She's the character Dory, voiced by Ellen DeGeneres.
Butterfly FishThe Butterfly Fish, belonging to the family Chaetodontidae, is known for its intricate patterns and vibrant colours. With over 120 species, these fish are a common sight in the Great Barrier Reef. They have a varied diet, feeding on coral polyps, algae, and small invertebrates.
Heniochus AcuminatusThe Heniochus Acuminatus, also called the Longfin Bannerfish, is easily recognizable by its elongated dorsal fin and black and white colouration. These fish are omnivorous, feeding on a combination of plankton, algae, and small invertebrates. Their graceful swimming patterns make them a delight to watch.
The famous Ocellaris ClownfishThe Ocellaris Clownfish, scientifically known as Amphiprion ocellaris, gained popularity through the movie "Finding Nemo." These small, orange fish with white stripes are found in the Great Barrier Reef and have a symbiotic relationship with sea anemones. They feed on small invertebrates and algae.
StarfishStarfish, or sea stars, are fascinating creatures found in the Great Barrier Reef. They come in various colours and sizes, with the ability to regenerate lost limbs. Starfish play a vital role in maintaining the reef's health by feeding on dead organisms and controlling population levels of other marine species.
Green Sea TurtleThe Great Barrier Reef, a world wonder known for its stunning biodiversity, is home to an incredible resident, the green sea turtle. These gentle giants, with their striking emerald hues, play a crucial role in maintaining the health of the reef ecosystem. As they gracefully navigate the crystal-clear waters, green sea turtles are a testament to the delicate balance of life in this magnificent underwater world.
Why is the Great Barrier Reef a world heritage listed area?
The Great Barrier Reef was designated as a world heritage listed area by UNESCO in 1981. This prestigious recognition is given to places of outstanding universal value. The reef is not only a natural wonder but also holds immense cultural and scientific significance. It is a living laboratory for researchers and a sacred place for the Indigenous people who have been custodians of the land for thousands of years.
How many tourists visit the Great Barrier Reef each year?
Every year, the Great Barrier Reef attracts more than 2.4 million of tourists from around the world. In 2019, the reef welcomed approximately 2.7 million visitors. People come from far and wide to witness the beauty of this underwater paradise and experience the wonders of snorkelling and diving.
Geo's time at the Reef
A couple of years ago we embarked on a journey to the Great Barrier Reef, a trip that held a special place in our hearts, especially for Geo, who was visiting the Reef for the very first time. Our adventure began with a coach ride from our hotel in Palm Cove, taking us north to the coastal town of Port Douglas. From there, we hopped onto a Quiksilver cruise bound for Agincourt Reef, where the real magic awaited.
With snorkel gear and safety vests firmly strapped on, we dived into the crystal-clear waters, spending hours in awe of the colourful marine life surrounding us. When our energy began to wane, we sought refuge in the underwater observatory and the glass-bottomed boat, which offered us a fascinating glimpse into the incredible underwater world of the Reef. Lots of photos were taken that day. We left with a profound appreciation for the beauty and biodiversity of this natural wonder.
What threats does the Great Barrier Reef face?
Despite its magnificence, the Great Barrier Reef is under threat. Climate change, pollution, and overfishing are some of the major challenges it faces. Rising sea temperatures due to climate change cause coral bleaching, which can lead to the death of coral reefs. Pollution from coastal development and agricultural runoff can harm the delicate ecosystem. Overfishing disrupts the balance of the reef's food chain, affecting the survival of various species.
Now, more than ever, it is crucial to protect the Great Barrier Reef. By supporting sustainable tourism practices, reducing our carbon footprint, and advocating for stronger environmental policies, we can help ensure the long-term survival of this extraordinary ecosystem.
