Original Description:

Word origin: Lysmata appears to be from the Greek roots Lys meaning loose and mat, -aeo, -eo, meaning foolish or idle. The species wurdemanni is apparently in reference to Wurdemann, (unknown) indicated by the Latin genitive ending -i. The literal translation for the genus seems a bit confusing and Lysmata may refer to the cleaner shrimps leaving the substrate (loose) to clean fish capable of eating them (foolish)The order Decapoda means “ten legs” (Deca indicating ten and pod meaning foot. The suborder Pleocyemata is from the Greek root(s); pleo meaning full, more; sail, swim; and cyem, -a, -ato, -I, meaning an embryo. The Infraorder Caridea is from the Latin root cari, -d, =s meaning shrimp The family Hippolytidae are the “cleaner” shrimp.. Hippolytidae appears to be a combination of hippo meaning “horse” and ly another word for loose, and idae being a standard suffix for an animal.
