Characters: Colonies are compact clumps reaching several metres across. There is no clear distinction between verrucae and branches as these intergrade with each other. Branches are highly compact and sturdy in habitats exposed to strong wave action and are thin and open in deep or protected habitats. Colour: Usually pale brown, greenish or pink. Similar species: Pocillopora danae, which has thicker branches and does not have intergrading verrucae and branches. Habitat: Occurs in all shallow water habitats from exposed reef fronts to mangrove swamps and wharf piles. Abundance: Common.
