Ceratosoma trilobatum can grow to a maximum size of 15 cm length.The body coloration is extremely variable but is always composed of bright colors. However, the body coloration is not a valuable criterion of determination for this species because it can easily be confused with
Ceratosoma tenue.
The physical distinctive criteria are two mantle lobes on the first half of the body on each side. The first one is around the head part and the second one is close to the gills. The purple margin of the mantle and foot is an unbroken line.

Another specificity of the species is the kind of "horn" covering the gills, which is like a lure and acts as a defensive chemical weapon that will scare any potential predator who dares to bite this part. The gills and the rhinophores are retractile in internal sheaths and their basis has a purple margin.
Also available in plastic form for self painting if desired.
