In Case You Didn't Know ...
The flatworms are a phylum of soft-bodied invertebrates that set themselves apart from other worms by the following characteristics:
  • They are unsegmented.
  • They have no body cavity, and no specialized circulatory or respiratory organs.
  • They are primarily carnivorous predators.
  • Their digestive system consists of a blind sac with a single opening that serves as mouth and anus.
Of the 50 species identified so far, 45 of them were discovered since DLIA has supported and coordinated this collection project. 7 species, so far, have been found to be new to science.
