Entobia convoluta Edinger et Risk, 1994

Type macroboring, substrate calcareous, tracemaker invertebrate.

 Diagnosis: Unicamerate to occasionally bi- or tri-camerate entobian with large irregular chambers, often exceeding 15 mm in diameter. Apertures large, generally not more than 2-3 (Figs. 6, 9). Most com- mon in scleractinian corals, but occasionally found in oysters. Description of fossil material: Infilled boreholes in Miocene corals Psammocora trinitatis, Montastraea limbata, and Porites trinitatis. Also occurs in a variety of Oligocene corals. Description of recent material: Modern borings matching E. convoluta are made by Cliona laticavicola. Large, complex unicamerate to bi-camerate galleries with large apertures, bright orange tissue. C. laticavicola is common in Caribbean massive and branching corals.
