''Acropora pulchra'' is a species of colonial stagshorn coral in the family Acroporidae. It is found on the back fringes of reefs in shallow water in the western Indo-Pacific Ocean. The oldest fossils of this species date back to the Pleistocene.〔 ==Description== The stony skeleton of ''Acropora pulchra'' takes on various forms. It is a branching species, sometimes being tree-like and forming thickets and in other locations forming tangled colonies with level upper surfaces. The branches are up to in diameter and up to long. Often the whole colony spreads horizontally and is no more than thick. The growth habit largely depends on where the coral is growing in relation to the tide levels. The polyps protrude from little cup-shaped depressions called corallites which are widely spaced on the branches and which have elongated lower lips. The colour of this coral varies from blue to various shades of brown, often with pale blue tips to the branches.〔
