External morphology. Cryptic specimens are encrusting, fleshy soft, slightly mucous; they cover 30–50 cm 2 area. Oscula are inconspicuous, generally about 1 mm, maximum 2 mm in diameter. Live color is bright red to orange red, some specimens were recorded to have a greenish yellow hue over dark red.
Skeleton structure. An irregular network of spongin fibers cored by (sub-) tylostyles, echinated by stubby acanthostyles. Smaller tylostyles are in the ectosome, some forming brushes at the surface.
Spicules. Styles, thickest near the rounded ends: 200–400 x 3–13 (318 x 7) Μm; (sub-)tylostyles I: 260–320 x 3–6 (283 x 5) Μm; (sub-)tylostyles II: 100–143 x 2–3 (122 x 3) Μm; acanthostyles: 38– 70 x 5–8 (50 x 7) Μm; regular toxas: 20–60 (35) Μm; rhaphidiform toxas: 108–280 (167) Μm; palmate isochaelas: 12–14 (13) Μm.
Ecology. All cryptic specimens were found either on concrete pillars under a boat dock, on the undersides of reef rubble, or inside small forereef caves; from 0.5– 21 m.
Distribution. Forida, Bahamas, Gulf of Mexico and throughout the Caribbean.
Comments. Branching growth forms of the sponge are also found in full light, both in reef and lagoon habitats.
