Coral of the Great Barrier Reef

-

  


The gardens of the oceans...

The Great Barrier reef is the world's largest coral reef system, boasting over 600 different species of corals in its waters. Although coral reefs may seem more sculpted from stone rather than life, corals are much like the flora of the earth—living organisms. 

One of the famed bragging points of this reef system is that it can be seen from outer space, an impressive feat considering that our manmade sculptures of metal and glass can't even be seen without extensive light *cough POLLUTION* illuminating the atmosphere. Additionally, this ecosystem is the largest to be created out of living organisms. Everything here is alive, and as fascinating as the fauna of the Great Barrier are, I think the flora deserve a spotlight too. 

Here are some of the most impactful, influential, and interesting corals I've learned in my Great Barrier Reef exploration. 

The Staghorn Coral (Acropora cervicornis) 


 Staghorn coral can be found all over the world, notably, the Carribean Sea. This species of coral is named after its antler -like arms; these unique structures provide habitats for many different kinds of fish contribute to maintaining healthy wildlife diversity in a multitude of ecosystems. They also have the ability to form limestone casings that help build onto coral reefs, maintaining the coral reef structure itself. However, like the majority of other corals, the Staghorn Coral is facing a declining population due to climate change, pollution, fishing practices, and other threats, which could severely limit the amount of limestone that can be produced in the world's coral reefs. 


The Flowerpot Coral (Tamoya ohboya)



These popular corals are coveted for their beautiful and flowing structures that come in a variety of colors. Formed by individual polyps that join together at the base, this species of coral has around 18-24 tentacles that wave around freely under the water. Hence, the Flowerpot Coral is considered to be a soft coral rather than the hard corals with rigid tentacles. 

The Organ Pipe Coral (Tubipora musica)


These corals are typically red and live in large colonies that occupy shallow waters of up to 12 meters in depth. Organ Pipe Coral are soft coral that have eight feathery soft tentacles attached onto the pipe-like tubes covered by a unique hard exoskeleton. These solid polyps are home to a type of phytoplankton, zooxanthellae, that in turn provide energy to the coral. This mutual relationship is just one example of the symbiotic relationships of corals. 

The Hump Coral (Porites polymorphus)


Commonly found in inner reefs rather than outer reefs, the Hump Coral actually prefers isolation from other species of corals. These are known to be some of the oldest corals on Earth, some possibly up to 1000 years old. During the day, the Hump Coral utilizes algae to photosynthesize, and at night, it filter feeds on plankton. 

The Smooth Cauliflower Coral (Stylophora pistillata)


Also known as Hood Coral, the Smooth Cauliflower Coral is a type of stony coral native to the Indo-Pacific region. This species of coral is considered to be an R-strategist, which means it is able to adapt quickly to unstable environments and reproduce in large quantities. There are typically six primary septa, plates forming the corallite wall, and six secondary septa. These can come in a multitude of different colors.  

The Honeycomb Coral (Diploastrea heliopora)


As its name suggests, the Honeycomb coral is a hard coral that grows in a dome covered in calcium carbonate cups, which is where the polyps are located. This is also known as brain coral and may be confused with the extinct genus Favosites. Although particularly common in the Red Sea, this species of coral can be found all over the Indo-Pacific region.

Fast Facts: Maori Wrasse

Known by many names, including the Humphead Wrasse and Napolean Wrasse, this fish is known as a king of the coral reefs.    The Maori Wrasse :   Cheilinus undulatus Description : Reaching up to 2 meters in length and 180 kg in weight, t he Maori Wrasse is the largest species in the Wrasse family. They are easily distinguishable by the hump on their foreheads, which become more prominent with age, as well as their puffy lips. Based on the age and gender of a Maori Wrasse, its color patterns vary from red and orange to yellow and green and blues.  Habitat :  Found in the Indo-Pacific's tropical waters, the Maori Wrasse tends to cling to the temperate-coastal habitats of Australia. Maori Wrasse can inhabit all types of reefs, from rocky reefs by the shore to off-shore reefs reaching depths of 60 meters.  Diet : Maori Wrasse are carnivorous creatures that feed primarily on crustaceans, mollusks, and other benthic creatures. They may even eat smaller fish! Maori Wrasse are significant t

Fast Facts: Yellow Tang

This fish is one of the most recognizable species in both the Great Barrier Reef and Gen Z's childhoods.    The Yellow Tang:   Zebrasoma flavescens Description : The Yellow Tang's bright full-body yellow coloration is what makes distinguishes it from other Tangs. They can grow up to around 8 inches in the wild and have a white barb used for defense and attack on each side of the base of their caudal fin; these barbs are considered to be modified scales of the Tang.  Habitat : A Yellow Tang lives in saltwater reefs all over the world, however, they are most commonly found near Hawaii; about 70% of the Yellow Tang population lives in these waters. This species is native to the Pacific Ocean but may also be found in the Atlantic Ocean.  Diet : As herbivores, Yellow Tangs feed exclusively on plants. Algae is their preferred food source, and Yellow Tangs may even eat the algae off of turtles as part of a symbiotic relationship.  Behavior : Although they do tolerate other individuals

Fast Facts: Giant Clam

   Not something you'd find at your local buffet.  The Giant Clam:   Tridacna gigas Description : As the largest mollusks in the world, Giant Clams can reach a size of four feet long and weight of 500 pounds. A Giant Clam's main feature, its shell, is made up of two halves that can open and close through use of a hinge. Although their shells range in various sizes, colors, and patterns, all Giant Clams have a fleshy interior mantel that can weigh up to a quarter of the clam's weight! Habitat : These mollusks are primarily found in waters of down to 20 meters in depth in the Indo-Pacific region and other tropical and subtropical areas. Because of their shallow environment, Giant Clams thrive in coral reefs where they embed themselves into the sand. In particular, they thrive in habitats with high calcium carbonate levels that strengthen their shells.  Diet : Through the filter feeding process, Giant Clams gain energy from their main diet of phytoplankton. However, Giant Clam
