REMARKS While often taken from fish hosts (sometimes in the gill cham- 

 ber), this species is equally frequently found freeliving in shallow water over 

 sand and coral rubble. The species will also attach itself to humans, inflicting 

 a sharp bite as it tries to feed.

DIAGNOSIS Eyes when present, relatively small, lateral. Frontal lamina 

 present. Mandible with tridentate incisor, lacinia mobilis, blade- or sawhke 

 molar, and palp. Maxillipedal palp of five articles, endite present. Coxal 

 plates present on pereonites 2-7, distinctly separated by suture from tergite. 

 Pereopods generally ambulatory, although anterior three pairs prehensile in 

 some genera, and posterior four pairs natatory in some genera. Pleon of five 

 free pleonites plus pleotelson in most genera; pleonite 5 with free lateral mar- 

 gins or overlapped by pleonite 4. Pleopods membranous, lacking ridges or 

 folds. Uropods situated at anterolateral angles of pleotelson, freely articulat- 

 ing, both rami well developed, mobile.
