Pectiniidae

Pectiniidae is a family of stony corals, commonly known as chalice corals. Members of the family are mostly colonial but one species, Echinomorpha nishihirai, is solitary. The name is probably related to the comb-like appearance of the walls of the corallites, which are tall, thin and striated. Pectiniids are endemic to the Indian and Pacific Oceans.
