Acrocnida brachiata displays the characteristic brittle star body plan with a flat central disc and five distinctly demarcated thin arms. As a member of the order Ophiurida, its arms are usually moved horizontally and the discs and arms are covered with scales. The circular disc can reach 12 mm in diameter and it has very long, thin and flexible arms. Like similar species, it has only one outer mouth papilla, clearly detached from the infradental papillae. It can be differentiated by the presence of two tentacle scales, ventral scales and radial shields with a transverse furrow. It is brown-grey in colour.
Acrocnida brachiata is well known to bury itself in sand with only the distal parts of the arms sticking out but is also often associated with Echinocardium cordatum.
