CD as "Thysanozoon or Acanthozoon spp." However, the translucent-white
body with opaque-white and black flecks doesn't match any of the illustrated
species well enough for me to suggest a match. I see the flecks become
more brownish apically on the papillae. But, that still doesn't help
much... I suppose there's some chance that it's a juvenile that could
develop more uniform pigmentation with growth. But, most flatworms have
their pattern pretty much "set" by 12 mm... A bit of on-line
searching (not comprehensive) yielded a somewhat similar animal from
Singapore (based on background, opaque-white flecks and eye spots).
But, that one lacks the dark flecks..."
