Acropora aspera
This branching species often dominates the intertidal zone where it can form monospecific thickets. Branch length is determined by tidal height, hence in some locations branches are short and stunted and low sprawling colonies form. Radial corallites have a well developed rounded lower lip and are tightly compacted on the branch. Brown, blue, grey, cream.
Morphology
Branching.
Evolution
Species age estimated to be 3.0161 mya.
Behaviour
Acropora aspera is a zooxanthellate coral which harbours symbiotic dinoflagelates in its tissues. The coral relies heavily on the energy produced during photosynthesis by these algae. It is often observed to contain a high mucous load which is considered a protective mechanism to enable the coral to tolerate the high temperature, light and wind conditions encountered in the intertidal zone.
Method of reproduction
Hermaphroditic spawner.
Habitat
Marine
This species is one of a small number that thrive in intertidal conditions but it can also be found subtidally.
Distribution
Indo-Pacific.
Life Cycle
The zygote develops into a planktonic planula larva. Metamorphosis begins with early morphogenesis of tentacles, septa and pharynx before larval settlement on the aboral end.
