Red coral: how to recognize it

It occurs in particular branched colonies that they can even measure over 30 cm in height. They are red, very bright red, but although the name sounds unquestionable, we can also find shades of pink. Not to mention the albino colonies that are completely white in color.

It is also composed of polyps, white and almost transparent, of about a couple of millimeters, equipped with tentacles bordered with pinnate appendages but which we can only see when the red coral wants to "catch" food.
