      this is good for kids learning on the great barrier reef I should of started with this site in the first place!
  • Soft corals, on the other hand, are often more visually striking than the hard variety and are differentiated by having eight tentacles as opposed to hard corals’ six, along with their lack of a solid exoskeleton. Soft corals generally have a squishy and/or leathery texture. Soft corals are especially important as they serve as home to one of the most essential food sources in the entire Great Barrier Reef – marine algae – on which the entire ecosystem is dependent on. The smallest of fish and other members of the Great Barrier Reef’s food chain use the algae as their main form of sustenance, and they themselves serve as food for larger predators, and so on – none of which would be possible without the many kinds of soft corals that populate the reef.
  • Great Barrier Reef Coral Coral forms the backbone of the structure of the Great Barrier Reef, and with over 400 species that comprise the various sections of reef, they play a huge part in making up the visual splendour that has contributed to its worldwide fame. The vibrant colours of the Great Barrier Reef coral can be striking, with vivid reds and cool blues coexisting side by side to form a veritable underwater rainbow which has to be seen up close to be properly appreciated. The Great Barrier Reef, like most other coral reefs on earth, initially grew from a hard surface on the ocean floor and continually evolved over the course of 500,000 years to take the shape of the vibrant ecosystem that can be found in today.

  • Hard corals (also known as stony corals) can typically be found in clear, shallow tropical waters and are the closest thing to a “construction force’ that the reef has, contributing largely to the relatively swift growth of the Great Barrier Reef as opposed to many of the world’s older major reef formations (many of which have existed for several million years.) The most common type of hard coral which can be found in the Great Barrier Reef is of the Staghorn variety, which over time form limestone casings that become an important building block in the reef’s expansion and providing more viable habitats for its many ocean-dwelling creatures to live in.
  • Types of Coral Corals are generally divided into two main groups, simply labeled “soft coral” and “hard coral” which are defined not only by their composition and texture but also by the number of tentacles that can be found on their adjoining polyps.

  • Coral reefs are made of thousands and thousands of minute coral polyps that are held together by coralline algae. Most coral reefs are several million years old and contain richly diverse life forms. The Great Barrier Reef is a coral reef, comprising more than 400 species of coral. It is considered the largest living organism in the world.
