The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres over an area of approximately 344,400 square kilometres. The reef is located in the Coral Sea, off the coast of Queensland, Australia. It is the residence of Marlin, Nemo, and Dory in the Finding Nemo movies and in the series.

## Description

It is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometers (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi).

## Role in Series

### "SICK BEATS"

When Boon and Ariana are talking to each other, parts of the reef are seen as backgrounds.

### "Animal Kingdom"

The Great Barrier Reef is the main location of this episode, where throughout, Antonio talks about the reef, it's organisms, and how humans affect it.

### "Antonio's Big Birthday Blowout"

The majority of the episode is set there, for the parts where the captin takes Antonio, Boon, and other tourists. They pass by the locations shown in *Finding Nemo*, *Finding Dory*, and "Finding Marlin" Part 1 and 2. They then meet the sea godess that Boon tries to sacrifice Antonio's life for.

## Locations

### Marlin's Former Anemone

This pink anemone is where Marlin and Coral once lived until the latter and all but one of their +400 eggs were all presumably eaten by a barracuda, causing Marlin to become overly concerned about Nemo's (his only surviving child) safety.

### Marlin and Nemo's Current Anemone

This orange anemone is where Marlin and Nemo currently live.

### Dory's Brain Coral

This is a hollowed-out brain coral serving as Dory's home after she moves in next door to Marlin and Nemo's anemone near the beginning of *Finding Dory*, one year after *Finding Nemo*.

### Mr. Johanson's backyard

This sandy pit is where the grouchy flounder Mr. Johanson lives. Many fish parents warn their kids not to play in his yard. However, when Mr. Johanson shows up, due to him being a flounder, is completely unable to find the intruders since his eyes are both on only one side of his face.

### Sponge beds

These sponge beds serve as a playground to the baby fish. A green parrotfish and a purple tang family usually hang out here, however, one of the baby purple tangs falls off the sponge beds and starts crying.

### Mr. Ray's schoolyard

This sandy pit acts as the schoolyard for the spotted eagle ray school teacher Mr. Ray. Many fish parents drop their kids off here at the start of each school day.

### Stingray Migration

This is a seaweed-filled field where Mr. Ray and his class go to view the annual stingray migration on their field trip.

### Bruce's Submarine

This is the area where Bruce, Anchor, Chum, and Blenny reside in. Marlin and Dory have been visitors there in the first Finding Nemo movie.

### Abyssopelagic Zone

it is a very deep part of the ocean where Philip Sherman's mask sinks into and in which Marlin and Dory encounter a very territorial deep sea anglerfish while trying to find the mask. Other species, like Hatchetfish, Tube Worms, and Gulper Eels reside there.

### East Australian Current

This is the area that is the last part from the Great Barrier Reef to Sydney. Crush, Squirt, and thousands of other sea turtles reside here.

## Ecology

The Great Barrier Reef supports an extraordinary diversity of life, including many vulnerable or endangered species, some of which may be endemic to the reef system.Thirty species of cetaceans have been recorded in the Great Barrier Reef, including the bottlenosed dolphin, dwarf minke whale, Indo-Pacific humpback dolphin, and the humpback whale. Large populations of dugongs live there. More than 1,500 fish species live on the reef, including the clownfish, regal blue tang, red-throat emperor, and several species of snapper and coral trout. Forty-nine species mass spawn, while eighty-four other species spawn elsewhere in their range. Seventeen species of sea snake live on the Great Barrier Reef in warm waters up to 50 metres (160 ft) deep and are more common in the southern than in the northern section. None found in the Great Barrier Reef World Heritage Area are endemic, nor are any endangered.

Six species of sea turtles come to the reef to breed: the green sea turtle, leatherback sea turtle, hawksbill turtle, loggerhead sea turtle, flatback turtle, and the olive ridley. The green sea turtles on the Great Barrier Reef have two genetically distinct populations, one in the northern part of the reef and the other in the southern part. Fifteen species of seagrass in beds attract the dugongs and turtles, and provide fish habitat. The most common genera of seagrasses are *Halophila* and *Halodule*.

Saltwater crocodiles live in mangrove and salt marshes on the coast near the reef. Nesting has not been reported, and the salt water crocodile population in the GBRWHA is wide-ranging but low density. Around 125 species of shark, stingray, skates or chimaera live on the reef. Close to 5,000 species of mollusc have been recorded on the reef, including the giant clam and various nudibranchs and cone snails. Forty-nine species of pipefish and nine species of seahorse have been recorded. At least seven species of frog inhabit the islands.

215 species of birds (including 22 species of seabirds and 32 species of shorebirds) visit the reef or nest or roost on the islands, including the white-bellied sea eagle and roseate tern. Most nesting sites are on islands in the northern and southern regions of the Great Barrier Reef, with 1.4 to 1.7 million birds using the sites to breed. The islands of the Great Barrier Reef also support 2,195 known plant species; three of these are endemic. The northern islands have 300–350 plant species which tend to be woody, whereas the southern islands have 200 which tend to be herbaceous; the Whitsunday region is the most diverse, supporting 1,141 species. The plants are propagated by birds.

More than 100 species of jellyfish have been recorded along the Great Barrier Reef, including the notorious stinging blue bottles and box jellyfish. One of these, the infamous Irukandji jellyfish, is one of the smallest (roughly one cubic centimeter) and most venomous jellyfish in the world.

There are at least 330 species of ascidians on the reef system with the diameter of 1–10 cm (0.4–4 in). Between 300–500 species of bryozoans live on the reef. Four hundred coral species, both hard corals and soft corals inhabit the reef. The majority of these spawn gametes, breeding in mass spawning events that are triggered by the rising sea temperatures of spring and summer, the lunar cycle, and the diurnal cycle. Reefs in the inner Great Barrier Reef spawn during the week after the full moon in October, while the outer reefs spawn in November and December. Its common soft corals belong to 36 genera. Five hundred species of marine algae or seaweed live on the reef, including thirteen species of genus *Halimeda*, which deposit calcareous mounds up to 100 metres (110 yd) wide, creating mini-ecosystems on their surface which have been compared to rainforest cover.
