Latest Great Barrier Reef Stories
Australia’s sea snakes may be more in danger of extinction than previously thought, marine scientists say.
As ocean temperatures rise, some species of corals are likely to succeed at the expense of others.
A team of international scientists working in the central Pacific have discovered that coral which has survived heat stress in the past is more likely to survive it in the future.
Researchers have partnered with Google in an effort to allow anyone with Internet access to take a virtual tour of Australia's Great Barrier Reef.
More than 300 eminent scientists from 21 other countries around the world today urged the Australian Federal Government to create the world’s largest no-take marine reserve in the Coral Sea.
One of the greatest biological threats to tropical coral reefs can be a population outbreak of crown-of-thorns (COT) sea stars (Acanthaster planci).
When it comes to choosing a place to hang out, big reef fish like coral trout, snappers and sweetlips have strong architectural preferences.
Recent experiments conducted at the Australian Institute of Marine Science (AIMS) produced striking results, showing for the first time that corals hosting a single type of “zooxanthellae” can have different levels of thermal tolerance – a feature that was only known previously for corals with a mix of zooxanthellae.
Two eminent tropical marine scientists today urged Australians to get behind a plan by the Federal Government to transform nearly a million square kilometers of the Coral Sea into the world’s largest marine park.
Australian scientists have urged greater consideration for the brilliantly-hued parrot fishes that tend and renew the world’s imperiled coral reefs.
The short-spined crown-of-thorns starfish (Acanthaster brevispinus) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that includes the Great Barrier Reef, the Philippines, and the Seychelles in the Indian Ocean. Because these areas are so far away from one another, the full range of this starfish cannot be known, but it can be said that it resides in a tropical or subtropical environment. It was first discovered by W.K. Fisher, who...
The Barrier Reef Anemonefish (Amphiprion akindynos) is native to the marine lagoons and reefs in the Western Pacific Ocean. It lives at a depth of around eighty-two feet in temperatures fluctuating between fifty degrees Fahrenheit to 89.6 degrees Fahrenheit. Its range includes northern New South Wales, the Loyalty Islands, Tonga, New Caledonia, Coral Sea, and the Great Barrier Reef. They are typically seen near or within the tentacles of their host anemones. They will inhabit anemones like...
Alcyoniidae is a family of leathery corals that occur globally in temperate and tropical seas. These reef dwellers are often found in wave-exposed areas of reef crests, less turbid waters in lagoons, on steep slopes, under overhangs, and at depths of 100 feet and deeper. A colony of leathery coral is stiff, hard, and inflexible. It is composed of tiny polyps projecting from a shared leathery tissue. There are two kinds of polyps seen in Alcyoniidae corals: autozooids have long trunks and...
The Elongate Surgeonfish, (Acanthurus mata), is a species of tropical fish found in the Indo-Pacific, and can be found as far north as Southern Japan and south to the Great Barrier Reef. Some also live as far west as South Africa and as far east as the Tuamotu Islands. Its main habitat is steep slopes around coral reefs. This is a light blue fish with numerous brown stripes running down the length of the body, although over time it is able to change color to become blue overall. It has a...
The Pajama Cardinalfish (Sphaeramia nematoptera) is a fish that belongs to the Apogonidae family. These fish are a popular aquarium fish. The Pajama Cardinalfish can grow to be a length of 3 inches. The fish has red eyes and broad, dark, vertical "waistband" that is sprinkled with red spots that leads toward the tail. This fish has low vulnerability. Pajama Cardinalfish circulate throughout much of the West Pacific, from Jave to Fiji and from south of the Ryukyu Islands to the Great...
