The whale shark is the largest fish on the great barrier reef. All Great Barrier Reef fish have ears, which is the only way for scientists to tell them apart from other fish. “It’s the largest fish in the world, but it’s also one of the most elusive.
It’s very hard to find, and very difficult to catch,” said Dr. David Goulson, a marine biologist with the Australian Institute of Marine Science (AIMS) in Townsville, who has been studying the whale sharks for more than 20 years. “They’re not easy to spot because they’re so large, so you have to be very careful when you’re out on the water, because you don’t want to get too close to them.”

What is the most common fish that live in the coral reef?
The most common reef fish we have seen are the striped parrotfish. The parrotfish, surgeonfish, and grunt families have been observed in our reef aquariums. We have a total of 8 different species that are commonly seen in reef aquaria.
The most commonly observed species are: Parakeet (Parakea leucas) – 1.5 to 2.0 million fish per tank. Clown Shrimp (Cephalorhynchus schweinfurthii) – 0.8 to 1 million per aquarium.
What is the most rarest fish in the Great Barrier Reef?
A species of fish never before recorded in Australian waters has been found in the depths of the northern Great Barrier Reef. The rhinopias agriloba is a scorpion fish that has never been seen in australia.
The discovery was made by researchers from the University of New South Wales (UNSW) and the Australian Research Council Centre of Excellence for Coral Reef Studies (CRCS) in Townsville, Queensland.
It is the first time the species has ever been found on Australian shores, according to the researchers, who published their findings in the Journal of Experimental Marine Biology and Ecology (JEMBE) on Thursday. The species is named after the island of Agri, where it was found.
“This is a very exciting discovery,” said lead author Dr. David Goulson, from UNSW’s School of Biological Sciences. “It is rare to find a new species in this region, let alone one that is so new to Australia.
What small fish live in coral reefs?
The thousands of species sound like characters in a science fiction novel, with names like dragonets, gobies, blennies, cardinalfishes, dottybacks, and sandgazers. These diminutive characters are the most diverse and abundant fishes in the world. In the wild, they are found in tropical and subtropical waters from the equator to the Arctic Circle.
They are known for their long, slender bodies, which allow them to swim through the water at speeds of more than 40 kilometers per hour (25 mph). In addition to their remarkable swimming abilities, many of these fish are also excellent swimmers, able to reach depths of over 2,300 feet (700 meters) and stay there for hours at a time.
What creatures live in the Great Barrier Reef?
The Great Barrier Reef is home to many species of concern. Some of the species of concern include inshore dolphins, whales, dugongs, sawfish, sea snakes, marine turtles and some fish and sharks. We protect marine animal species that are threatened. We also work with local communities to help them understand the importance of protecting the reef and its wildlife.
How many fish live in coral reefs?
Coral reefs are some of the most valuable and biologically diverse in the world. 25 percent of all marine life, including over 4,000 species of fish, is dependent on coral reefs at some point in their lives. In the past few years, however, scientists have begun to notice an alarming decline in the health of some of the world’s most important coral reef ecosystems.
In particular, the Great Barrier Reef, a UNESCO World Heritage Site, has been hit hard by the effects of climate change and overfishing, which has led to coral bleaching events that have resulted in mass coral die-offs in recent years. These events have been linked to global warming and ocean acidification, both of which are expected to increase as the planet warms.
What herbivores live in the coral reef?
There are two types of animals on the coral reefs. The invertebrate herbivores include crabs, limpets, and polychaete worms. Sea turtles, reef fishes, and seahorses are some of the prominent vertebrate herbivores. Coral reefs are home to a wide variety of marine animals, including fish, crustaceans, snails, mollusks, corals, sponges, bivalves, amphipods, cephalopods (octopuses, squid, cuttlefish, etc.), and many more.
Many of these animals live in symbiotic relationships with the plants and animals that live on the reef. For example, coral polyps and coralline algae provide food and shelter for fish and other marine life. Coral reefs also provide habitat for many marine mammals, such as whales, dolphins, porpoises, seals and sea lions.
What is the smallest fish in the Great Barrier Reef?
The stout infantfish was discovered during a survey on the great barrier reef. The fish is just 7mm in length and 1mg in weight, which is tiny, but the word “tiny” on this page is a bit of a misnomer.
The species name is derived from “stout” and “infant” which are both used to describe the fish’s colouration. The species is also known by its common name, the “Infant Fish”, which refers to the fact that it is the smallest of the three species of infant fish that are known to exist in the world.
