Did you know?<\/h3>\n

Coral is often mistaken for a colourful plant that sits at the bottom of the ocean, but it is in fact an animal! This complex and beautiful creature plays a major role in marine life, not to mention fighting an ever-growing threat to its existence. Living for hundreds of years, coral (Anthozoa)<\/em> is closely related to other popular sea creatures including jellyfish and anemones.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n\n

Biology<\/h3>\n
\n
\n

Coral is made up of lots of tiny polyps. A polyp is a soft-bodied organism, shaped like a cylinder with a mouth at one end and surrounded by tentacles. At the base of each polyp there is a hard base called a calicle.<\/p>\n

 <\/p>\n

Coral polyps can live on their own, but often live in close proximity to form a colony \u2013 this allows them to share resources and grow larger. When a large colony forms, this creates what we know as a coral reef. However, it\u2019s important to note that only some coral are known as reef-building corals \u2013 these species will produce a harder outer skeleton made of calcium carbonate, which gives coral its rocky appearance and is often why it\u2019s mistaken for a plant.<\/p>\n

 <\/p>\n

With over 6,000 species of coral, they all differ slightly in appearance. For example, staghorn coral (Acropora cervicornis)<\/em> has a branching structure that can reach up to 2 metres in length, while lettuce leaf coral (Agaricia tenuifolia) <\/em>has fronds with ruffled edges.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n\n

Habitat<\/h3>\n
\n
\n

<\/p>\n

Coral can be found in all the oceans across the world. Different species live in different environments \u2013 some will thrive in colder, deeper waters while others need a more tropical home. Corals originating in tropical climates typically live no deeper than 60 metres from the surface. This is because of the zooxanthellae algae that live in the coral\u2019s tissue, which needs sunlight in order to photosynthesise.<\/p>\n

 <\/p>\n

<\/p>\n

The biggest coral reef is, of course, the Great Barrier Reef off the coast of Australia. You can also find coral reefs around Indonesia and the Philippines.<\/p>\n

Role<\/h3>\n
\n
\n

Coral reefs are some of the most complex ecosystems in the sea, with coral serving a number of purposes. Coral provides habitats for much of marine life, with fish, reptiles and other creatures calling a coral reef home. They are often known as the rainforest of the sea, thanks to its biodiversity.<\/p>\n

 <\/p>\n

Coral have a symbiotic relationship with other sea creatures, which means both parties benefit. For example, coral provides protection to the zooxanthellae algae living in its tissue, and in return the coral gets its energy through the algae\u2019s photosynthesis.<\/p>\n

 <\/p>\n

However, coral also offers benefits for people on land too. Coral reefs can provide important protection from storms, serving as a barrier for the impact of large waves that might reach the shore. People around the world rely on the fish caught around coral reefs too, not to mention tourism for local economies from people wanting to visit the reefs.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n\n

Corals are truly fascinating, with a few fun facts that you might be interested to know\u2026<\/p>\n

 <\/p>\n

    \n
  • Corals first appeared over 500 million years ago! They have been found in fossil reefs as old as this, which means they were around during the time of the dinosaurs.<\/li>\n
  • Most coral reefs you see today started growing over 50 million years ago.<\/li>\n
  • Corals are actually translucent \u2013 they get their bright colours from the zooxanthellae algae that live within them!<\/li>\n
  • When corals are stressed due to environmental change, they expel the algae which is why the coral turns white \u2013 this is known as coral bleaching.<\/li>\n
  • Coral support around 25% of marine life, but it only covers less than 1% of the ocean floor!<\/li>\n<\/ul>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"featured_media":1771,"template":"","meta":{"_acf_changed":true},"animal_type":[7],"class_list":["post-1762","animal","type-animal","status-publish","has-post-thumbnail","hentry","animal_type-invertebrates"],"acf":[],"yoast_head":"\nCorals - Blue Planet Aquarium<\/title>\n<meta name=\"description\" content=\"Learn all about Coral with Blue Planet Aquarium.
