Species of this large genus feature a wide variety of coloration and patterns, widespread distribution throughout much of the world's tropical oceans, and are often sought out for aquarium trade. Taxonomy This genus has undergone several changes in classification based on recent molecular studies comparing species within the genus. However, most recent molecular studies have only involved approximately 20% of the known species likely to belong to the genus. Additionally, most of the molecular studies performed involved Indo-Pacific species of ''Periclimenes'' and did not include presumed ''Periclimenes'' found in the Atlantic Ocean. ''Periclimenes'' has previously been suggested as being a polyphyletic taxa, and has already undergone splits into several new genera. It is likely the genus will undergo changes in ...
