Scale bar=10 um. , Littlewood leg., Aug. 1995, 1 postlarva from the stomach of a kingfish, Port Royal, Kingston, Jamaica. Description. The scolex of a specimen from C. limbatus is shown in Fig. 26. Measurements: SL=1210, 1134, 1000; SW=700, nm, 493; pbo=700, 642; 500; pv=510, 473, 500; pb=448, 330; 307; ppb=95, 75, 27; vel=170, 232, 160; BL=442 (428-448), 326 (312- 331),287(280-294);BW=128(126-130),104(84-107),81 (75-92); BR=:1, :1; :1; SP=:1, :1, :1. The ten- tacles are long and slender, with TW=27-30; 23-28, 20-22; TSW increases in size towards the base of the tentacles (24-27, 22-28, 29-32), a basal tentacular swelling is absent. Prebulbar organs are absent and muscular rings around the basal part of the tentacle sheaths are present in specimens from Carcharhinus spp. The retractor muscles originate at the base of the bulbs. The tentacular armature is homeoacanthous, heteromorphous, and a characteristic basal armature is absent (Figs 27-28). The hooks diminish in size towards the basal part of the tentacle, the hooks are rose-thorn shaped on both sides of the tentacles. The single hook sizes of the three specimens in the metabasal armature were L=, B=; L= , B=; L= , B= (mean L bothridial=) and L=, B=; L=, B=; L=, B= (mean L antibothridial=), and in the basal part of the tentacle L=, B=; L=, B=; L=, B= (bothridial) and L=, B=; L=, B=; L=5-6, B=5-6, (antibothridial); hsr=6-7.
