Description
''Alpheus macrocheles'' grow up to 35 mm long
and have a cheliped morphology.
[Soledade, Guidomar & Terossi, Mariana & Scioli, Justin & Mantelatto, Fernando & Almeida, Alexandre. (2019). A new western Atlantic snapping shrimp of the Alpheus macrocheles group (Caridea, Alpheidae) revealed by morphological, molecular and color data. European Journal of Taxonomy. 10.5852/ejt.2019.581. ] The chela is highly twisted and compressed, and the dactylar articulation deviates from the perpendicular plane to the dorsal margin.
There is often distinct grooves on the chela's lateral face.
Most individuals of this species are bright orange, however yellow individuals also exist.
Like other species within the genus ''
Alpheus'' the claws of ''Alpheus macrocheles'' are asymmetrical, with one of the claws being larger than the other.

Habitat
''Alpheus macrocheles'' is a marine species.
It can be found living underwater in fissures and hollows underneath rocks and boulders.
They generally favour larger boulders on the lower shoreline.
The oceans current pushes sediment such as sand into the hollow, which allows ''A. macrocheles'' to excavate tunnels.
Tunnels are usually shared by a breeding pair and possess two entrances, with each entrance being guarded by an individual shrimp.
