Characters: Colonies may form a continuous cover over the substrate many metres across although individual colonies are seldom over one metre across. Colonies have the same skeletal structure as Euphyllia divisa. Polyps have large tubular tentacles with few or no branchlets but with anchor, hammer or T-shaped tips.
Colour: Blue-grey to orange, usually with pale cream or green outer borders to the tentacles.
Similar species: Euphyllia divisa has an identical skeleton but distinctive tentacles. Euphyllia paraancora has similar tentacles but is phaceloid.
Habitat: Large colonies are usually found in shallow environments exposed to moderate wave action.
Abundance: Seldom common, but may be a dominant species on protected horizontal substrates and on rocky outcrops in high latitude locations.
