CO OZNACZA SŁOWO FLATWORM
Flatworm
Płastunie, Platyhelminthes, Plathelminthes lub Platyhelminths (od greckiego πλατύ, platy, znaczy "płaski" i ἕλμινς (root: ἑλμινθ-), robak roboczy), są rodzajami stosunkowo prostymi, bilaterialnymi, niezaegmentowanymi, miękkimi bezkręgowców. W przeciwieństwie do innych bilaterianów, są to aeroelomaty (nie mają jamy ciała) i nie mają specjalistycznych narządów krążenia i oddechowego, co ogranicza ich do spłaszczenia kształtów, które umożliwiają dyfuzję tlenu i składników odżywczych przez ich ciała. Wnęka trawienna ma tylko jeden otwór zarówno dla spożycia (spożycia składników odżywczych), jak i egestionu (usuwania niezdatnych odpadów); W rezultacie żywność nie może być przetworzona w sposób ciągły. W tradycyjnych tekstach zoologicznych Platyhelminy podzielone są na Turbellaria, które są przeważnie zwierzętami nieparasitic, takimi jak planarianie i trzy całkowicie pasożytnicze grupy: Cestoda, Trematoda i Monogenea; jednakże, odkąd okazali się, że turbellarians nie jest monofilkularna, ta klasyfikacja jest obecnie przestarzała.
