Corals are marine invertebrate in the class Anthozoa of Phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans & secrete calcium carbonate to form a hard skeleton.

Coral Anatomy



Basic Types of Corals

There are two main types of corals.

  1. Hard coral
  2. Soft coral

HARD CORAL


Hard corals are made of a rigid, calcium carbonate (limestone) & appear very much like rocks. Each polyp secretes a hard exoskeleton made up of calcium carbonate  & a chalky internal skeleton that stays in place even after they die. As each generation of polyps dies & their exoskeleton remains, the coral grows a bit larger & because each polyp is so small, hard corals grow at a very slow rate. Hard corals are scientifically known as " scleractinians".

Types Of Hard Corals

                         Staghorn Coral


Pillar Coral


Table Coral


Brain Coral


Blue Coral


Great Star Coral


Tube Coral


Elkhorn Coral



SOFT CORAL


Soft corals are also composed of some rigid calcium carbonate, but it is blended with protein. So it is less rigid than hard corals. These corals are "rooted", but because they have no exoskeletons, they sway back & forth with the currents, appearing to be more like plants blowing in the breeze.

Types Of Soft Corals

Gorgonian (a.k.a.Sea Fans)


Carnation Coral


Toadstool Coral


Tree Coral


Sea Pens


Bubble Coral

    WhatYouSea sells coral frags on the internet for people with saltwater aquariums. A coral frag is a small piece of live coral that a person can add to their tank,and grow out. The niche should be blogs related to saltwater aquariums, and coral propagation and sales. Let me know if you need more information.
