MZB. Asc. 00001 Habitat. Coral limestone at reef crest. Remarks. Colonies were dome-shaped. Several morphotypes in colony shape and color exist in this species (i.e., brown, gray, white, large, and small type). These morphotypes can also be distinguished by the partial sequence of the cytochrome oxidase subunit I (COI) gene ( M. Hirose et al. 2009 ; Hirose et al. 2010a ). Brown-type colonies were found in the present survey. Prochloron cells were distributed within the common cloacal cavity. Testis and/or oocyte were found in some zooids. Figure 2. Photosymbiotic ascidians with tunic spicules. Colonies in situ and tunic spicules (inset) of Didemnum molle (A), Trididemnum miniatum (B), Lissoclinum patella (C), Lissoclinum punctatum (D), and Lissoclinum timorense (E). Tunic cells contain Prochloron cells in the tunic of Lissoclinum punctatum (F). Scale bars = 20 µm .
