Acanthozoon sp. or Thysanozoon sp.


Black with whitish cream blotches. Yellow-orange papillae tips. Grayish white lining along the edge. Belongs either to the Acanthozoon or Thysanozoon genera. Rather difficult to determine exact genus without microscopic examination. Acanthozoon has only one male pore while Thysanozoon has two. References :


A rather long flatworm - almost 6 in (15 cm) long. Night dive at sandy portion of the Classroom at Dive and Trek. Depth of about 6 m. Inclined to go with Acanthozoon sp. 02 with a similar spotting at Anybody care to confirm? Thanks.

Hi Birding For Fun. Yup it was particularly against the sandy bottom. Almost missed it and in fact only saw its true colors when the pictures where taken :-)
