Stylasteridae, also known as lace corals, is a family of colonial hydrozoans with a calcified skeleton.[1][2] They first appeared 65 million years ago in deep waters.[3] About 10% of the species have adapted to live in water less than 50 metres (164 feet) deep.[4] The rest are found in deeper water, most commonly between 200 and 400 metres (656 and 1,312 feet), with the deepest known species observed at a depth of 2,789 metres (9,150 feet).[3]
In shallow reefs the Stylasteridae can grow up to 25 centimetres (9.8 in) tall and 30 centimetres (12 in) wide,[5] but some species in deeper waters can reach 1 metre (3 ft 3 in).[3][clarification needed]
