Remarks :
 The exact genus can only be determined by checking how many male pores there are on the ventral side, one in Acanthozoon and two in Thysanozoon.
Newman (2003). Looks like one of the undescribed species Acanthozoon / Thysanozoon sp3, but in this species, white dots form irregular clusters on the rim and the background colour is more
dark red to orange than dark grey greenish.
Bibliographic data :
Rim without white dots forming irregular clusters in this specimen.
