Pond Sock Reef (9°17’17.9” N, 82°19’39.9” W), from fine-grained sand at 2 m depth collected from sediment surrounding a sunken boat; Isla Colon, Mangrove Inn (9°19.870’ N, 82°15.286’ W), from fine-grained sand at 3–4 m water depth. Description . Mature specimens ~650 µm long and ~160 µm wide (Fig. 1 A). Anterior end rounded; posterior sometimes somewhat pointed. Body without conspicuous coloration. Body-wall musculature with longitudinal fibers positioned outside of circular fibers. Ventral musculature with U1 and U2 muscles (sensu Tekle et al. 2005): muscles that are longitudinally oriented in the anterior half of body and wrap around posterior rim of mouth, and modified circular muscles whose mid-points line the posterior rim of the mouth and whose lateral extensions are positioned anterior to the mouth (data not shown). Separate male and female gonopores. Male copulatory organ with fine penis stylets in cone-shaped arrangement (Fig. 1 B). Remarks . Prior to this collection, Childia crassum was known only from the Eastern North Atlantic Ocean (see Tyler et al. 2006). Our specimens were approximately half the length of those originally described by Westblad (1942), with correspondingly smaller internal structures.
