The Devonshire Cup Coral - Caryophyllia smithii - looks initially like an anemone. However, it is a true coral with a hard, stony body about 1.5cms high. It is usually found in rocky areas and prior to underwater photography becoming a popular hobby, it was thought to be confined to south western coasts - hence the use of the word "Devonshire" in its name. It is now realised that it is found all around Northern Britain. It is very variable in colour and the soft part of its body and tentacles, which project from the skeleton when the animal is undisturbed, can range from green to yellow to red.
