Acropora Hoeksemai Video Stock Footage
Acropora hoeksemai is found in colonies that can be 1 to 2 m (3.3 to 6.6 ft) wide, made of branches joined in the centre of the structure. Some larger colonies have been observed at over 4 metres (13 ft). It is a light brown, white, or cream colour, and the branch ends are upturned, except on the outside of the structure. These branches are not regular, and contain both axial and radial corallites. Axial corallites can have diameters of between 2 and 2.6 millimetres (0.079 and 0.102 in). Radial corallites are tube-shaped, neat, orderly, and they are the same sizes. They contain basic spinules. The branches may grow to lengths of up to 150 millimetres (5.9 in) and diameters of between 7 and 15 millimetres (0.28 and 0.59 in). It is found in marine environments in shallow reefs at depths of 8 to 20 m (26 to 66 ft), and also on slopes and walls of reefs. It reaches maturity at between three and eight years, and it is believed to survive for more than ten years. It is composed of aragonite (calcium carbonate). When grown in captivity it reaches lengths of up to 25 centimetres (9.8 in). A. hoeksemai looks similar to Acropora valenciennesi and species of the Acropora divaricata group.
