Biology     Glossary (e.g. epibenthic)

This is one of the largest ascideans and is often coated in mud (Ref. 305). Assumed maximum total length from Ref. 1758. On a mangrove (Ref. 415). Found in mud, sand and silt bottom (Ref. 1134); lives on the bottom, often embedded in sediments (Ref. 1758). Filter-feeder (Ref. 68823).
