Euphyllia divisa
Euphyllia divisa, commonly known as frogspawn coral and sometimes misspelled Euphyllia divisia, is a large-polyped stony coral native to the Indo-Pacific islands. It is a commonly kept species in the marine aquarium hobby. The related coral Fimbriaphyllia paradivisa is frequently misidentified as frogspawn leading to some confusion. Fimbriaphyllia divisa has a corallite skeleton with a flabello-meandroid "wall" structure whereas Fimbriaphyllia paradivisa has a tree-like branching structure with separate corallites.
