Fire coral is a marine animal but not like other true corals. It is spotted around the Caribbean, as well as the main oceans around the world. Many people have confused these corals with seaweeds. These fire corals are considered to be slightly more harmful than other coral reef cuts. This is mainly because fire coral has an ability that leaves a stinging effect on the object that comes in contact with it. The sting is supposed to be warm and has symptoms with a severe burning effect on the surface. This is also one of the reasons they are called 'Fire'.
