- Gastrophanella cavernicola Muricy & Minervino, 2000 (Figure 2 c) Synonymy and references. Gastrophanella implexa Schmidt, 1879: sensu Macintyre et al., 1982: 134, fig. 83 b; Gastrophanella cavernicola Muricy & Minervino, 2000: 600, figs. 2–5. Material. USNM 32868, Columbus Cay cave, Belize, 20 m, ceiling, 20 m from entrance; I. G. Macintyre col. 26 Apr 1979. USNM 32871, Columbus Cay cave, Belize, 18–21 m, ceiling; B. Lester col. 24 Apr 1979. USNM 32875, Columbus Cay cave, Belize, 30 m, wall; C. Feller col. 25 Jun 1983. External morphology. Massive, lobate, up to 20 mm thick and 50 mm in diameter. Single oscula on top, up to 3 mm in diameter, with radiating vein-like canals just below the surface; small patches of ostia in surface depressions and along the sides of specimens. Surface finely rough, consistency hard, color in life cream. Skeleton structure. In the choanosome there is a dense reticulation of fused desmas, with tylostrongyles mixed in and also radiating toward the surface where they form a disorganized palisade with tyles outward Muricy & Minervino, 2000, fig 3). Spicules. Monocrepid desmas, 220–360 (280) Μm in diameter; tylostrongyles, 250–480 x 2.5–11.4 (358 x 6.4) Μm (measurements from Muricy & Minervino, 2000, tab. 1, figs 4, 5). Ecology. In dark areas of caves, 3– 30 m. Distribution. Northeast Brazil and Belize. Comments. The “Blue Hole” record from Lighthouse Reef atoll, Belize (Muricy & Minervino, 2000) is erroneous, due to a misunderstanding. Columbus Cay cave is a drowned karst cave, just like the famous “Blue Hole” of Lighthouse Reef some 60 km east-northeast, but its entrance tunnel on the lagoon floor (see Macintyre et al., 1982) is more like a black crack although local fishermen refer to it as “blue hole.” In Belize, Gastrophanella cavernicola has so far only been recorded from Columbus Cay cave.
