What You Need to Know About Hard and Soft Corals

One of the things that many people don’t know about corals is that they are animals of the invertebrate category, which is connected with a large group of colourful and amazing animals known as Cnidaria. There is also another animal that belongs to this group that you can see in the rock pools and on the beaches, which consists of sea anemones and jellyfish. Another thing that you ought to know is that cnidarians come in a huge variety of shapes, sizes, and colours. Plus, they all share similar characteristics that are distinct, like a plain stomach, a single mouth, and stinging tentacles. And, although the single coral animal is called a “polyp,” there are several who live in groups of 100 to 1000 identical polyps, which form a colony.

Corals can be classified into two categories. One is known as hard coral, and the other is known as soft coral. There are reef building corals also which is the hard coral species and its around 800. Then, there are soft corals, also known as sea feathers, sea fans, and sea whips, which don’t have a rock-like calcareous skeleton like others; rather, they grow in a core, which is like wood for support or help, and fleshy peels or skin for protection. Soft corals are the ones that reside in colonies and often look like brightly coloured trees or plants. They can be easily differentiated from the hard corals as the polyps have eight tentacles and have a distinctive feathery look.

Soft and Hard Corals

In oceans one can find the soft corals from the south and north equator poles and mostly in ledges and caves. In this, they hang down so that they can catch food that is floating in the currents and is typical of these places. Let’s look at coral reefs. Hard corals are the ones that suck up a lot of calcium from the seawater surrounding them, and it is used to develop a hardened structure for growth and protection. Coral reefs are the ones that are developed by tiny polyps in millions forming a large carbonate structure, and they are one of the bases for a framework and home for other categories of species in thousands. Coral reefs are the biggest living organism or structure on the planet and the only living thing to be visible from space.

Evolved Long Time Back –

Plus, people should also know that coral reefs have evolved on the earth for the past 300 million years, and over this history, the most sui generis skins of corals have evolved in a highly evolved form of symbiosis. Coral polyps have created this relationship with a small, single plant known as zooxanthellae. Inside the tissues of every coral polyp live these single-celled microscopic algae, which share space and exchange gas and nutrients to survive. This symbiosis that is there between the plant and animal contributes to the brilliant colours of coral, which can be seen when diving on a reef.
