Agelas citrina

Notes: Pinkish, tan or orange, ear-shaped thick fans; orange when filling crevices. The latter may be confused with Clathria faviformis Lehnert & van Soest, 1996, pictured here. It may be confused with Agelas clathrodes (Schmidt, 1870), also pictured here, which is harder. A. citrina has a thick skin, which in some portions forms conules or it is stretched over depressions. When they co-exist in the same locality, they can be distinguised by color, being milkier and lighter in A. citrina. Spicules are acanthostyles.
