is a family of acoelomorph
The family is divided into five genera (see taxobox
) and contains about 20 species (Turbellarian taxonomic database, 2006). The affinities of the genera are as yet unclear. Some biologists prefer to exclude the genus Praesagittifera
, leaving into the family only the genera with sagittocysts
(Achaz et al, 2005).
Sagittiferidae are small flat worm-like animals. Several of them grow symbiotic algae Tetraselmis
in their body cavity and tissues.
Special characteristics include a ciliated or non-ciliated sac-like male antrum. Most
members have sagittocysts (Kostenko&Mamkaev,1990)
