Description. Irregularly globular to flattened sponges ( Figs 118 View FIGURE 118 a,a1), inhabited by a hermit crab (which usually has a gastropod as its primary house), resembling similar Suberites -hermit crab associations (‘mobile’ sponges). Surface undulating but smooth. Usually with a single larger oscule at the opposite side of the hermit crab hole. Color in alcohol yellow to grey. Size variable, from 1 cm to 11 cm in diameter. Consistency firm.

Skeleton. At the surface a palisade of spicules, internally confused with vague tracts and large numbers of loose spicules.

Spicules. ( Figs 118 View FIGURE 118 b–c) Oxeas only.

Oxeas, predominantly sharply pointed, occasionally with stylote modifications, in a large size range, divisible in a (1) larger ( Figs 118 View FIGURE 118 b,b1), 231–279 µm, and a (2) smaller ( Figs 118 View FIGURE 118 c,c1), 99–186 µm category; overall dimensions 99– 214 –279 x 4 – 5.6 –7 µm.

Distribution and ecology. Guyana Shelf, North Carolina, Gulf of Mexico, Florida, Venezuela, on sandy bottoms from the intertidal down to 88.5 m depth ( Guyana Shelf 36–88.5 m).

Remarks. Several studies about the behavior of pagurid crabs, Paguristes hummi and Pagurus impressus , inhabiting this sponge have been published ( Sandford 1994, 1995; Sandford & Brown 1997). The species has a wide distribution, which is further extended east and southward, and deeper, by the present records.
