Nalicora rapax Moore, 1901 Figure 78 FLABELL1FERA • CYMOTHOIDAE 169 DIAGNOSIS 6 6.9 mm, ovigerous 9 10.0 mm. Eyes well developed. Frontal lamina basally slender, widening anteriorly, apex subacute. Posterior half of body bearing numerous scattered stiff setae. Pereonites 4-7 with row of low rounded tubercles near posterior margin. Posterior margins of pleonites 3—5 faintly tuberculate, more noticeable in 6. Pleotelson wider than long; lateral margins faintly sinuous; apex rounded. RECORDS Florida Keys, 55 m; Puerto Rico, 50-150 m; Gulf of Mexico off Florida, 37-73 m. Family Cymothoidae Leach, 1818 DIAGNOSIS Antennules and antennae reduced, no clear distinction between peduncles and flagella. Mandibular palp of three articles. Maxilla 1 with four terminal spines. Maxilla 2 apically bilobed, armed with several spines. Max- illipedal palp of two articles, terminal article bearing hooks. All seven pairs of pereopods prehensile, ending in strongly hooked dactyli. Pleopods lacking marginal setae in adults. REMARKS The cymothoids are exclusively ectoparasites on marine, fresh water, and brackish-water fishes. Most cymothoids occur in shallow water, mainly in tropical and subtropical areas. The position of attachment on the host (externally, in the buccal cavity, or in the gill chamber) is usually genus- or species-specific. The body of gill parasites is often asymmetrical, being slightly twisted, perhaps an effect of the position on the host. The mouthparts are highly adapted for the parasitic mode of life, while all seven pairs of pereopods are strongly prehensile. The posterior pereopods of some genera have the basal article expanded and carinate, allowing for increased mus culature. The secretion of anticoagulants in the juvenile stages further aids the blood-feeding habit. The surface area of the pleopods is often increased by the development of lobes on the bases or the lamellae, providing an in creased respiratory ability. The post-mancal juvenile stages (sometimes referred to as the aegathoid stage) have large eyes, and highly setose pleopods for active swimming. The juveniles will attach themselves indiscriminantly to any convenient fish host, but eventually attach to the preferred host-species. The juvenile then de velops into a functional male, losing the swimming setae of the pleopods. Both juveniles and males feed actively, drawing blood from the host fish. The
