Description
An isolated piece of fire coral with the sandy bottom of the ocean in the background. This was taken at about 30 feet. It gets its name from how your skin feels if you happen to brush against it. It is also called stinging coral for a similar reason. The pain is not severe or toxic but neither is it very pleasant. The reaction is caused by stinging nematocysts on the tentacles of the tiny polyps that line the outside edge of the coral. The corals themselves are hydroid colonies that secrete calcium skeletons. There are thousands of pinpoint pores in the skeleton through which polyps extend. There are sensory or stinging polyps that surround a non stinging, feeding polyp. They can form several shapes. This is an example of a branching coral.
