Discussion
- Hermaphroditic, so kap_R is halved
Facts
- Formerly known as Dugesia p. (Ref: Wiki)
- ectolecithal eggs in cocoon: in these eggs, one or several small yolk-poor oocytes are surrounded by large numbers of yolk cells which are produced by a specialized gland, the vitellarium. (Ref: Wiki)
- Triclads show a unique mode of cleavage called blastomere anarchy. Instead of remaining together and forming an ordered morula of micromeres and macromeres as in other spiralian embryos, blastomeres of triclad embryos lose contact and migrate actively to various positions within the syncytial yolk (Ref: Wiki)
- Temp range: 10-23 for cocoon prod, 05-23 for egg development, 10-23 for maturtion & life cycle (Ref: Wiki)
- feeding on wounded living prey (Ref: Wiki)
