Seriatopora hystrix

Dana, 1846


Lamarck, 1816

Characters: Colonies may form extensive stands. Branches are thin and tapered to a point, hence they have a needle-like appearance. These may be either widely spaced or compact, up to 150 millimetres long, and usually fuse in an irregular manner. Colonies with short thick branches are normally found in habitats exposed to wave action. Corallites are arranged in neat rows along branches. Polyps are not extended during the day.

Colour: Pink, less commonly cream, blue or green.

Similar Species: Seriatopora caliendrum, which has thicker branches which do not taper. See also S. guttatus.

Habitat: Shallow reef environments especially intertidal reef flats.

Abundance: Common.

Taxonomic Note: A species complex.
