Of all the wonderful marine creatures living in the cool, clear waters around Alderney, the sea corals and anemones are without doubt the most colourful. Together with jellyfish they belong to the phylum Cnidaria, which references the cnida, or stinging cells, that they all possess.
Anemones consist of a central column, containing the mouth and digestive cavity, surrounded by a ring of hollow tentacles. Each species has evolved to live in a specific part of the undersea environment. Some thrive on the seashore while others prefer the deeper water of Alderney's rocky reefs and shipwrecks.
Channel Island waters are home to at least nine different species of coral. While they do not form the vast reefs of their tropical cousins, they lack none of their colour or beauty.
