Figure F3. Entobia isp. (SEM images of resin casts, “negatives” of boreholes inside the carbonate) produced by clionaid sponges. Fine filamentous casts/​traces likely represent borings of the endolithic green alga Ostreobium. A. Large Entobia chambers show a verrucose surface sculpture, imprints of carbonate-carving cells. B. Exploratory extensions emanating from large Entobia chamber. C. Exploratory Entobia tunnel. D. Detail of exploratory extension. E. Detail of scars left by carbonate-carving sponge cells. Note concentric surface feature marking the progression of cell margins carving carbonate chips. F. Tip of Entobia exploratory tunnel protruding from coral skeleton.
