Yeovil's habit of giving away late goals again proved expensive as Dagenham won a crucial relegation battle 3-1.
Yeovil created but missed early chances and fell behind on 18 minutes when a right-wing corner from Danny Green was headed in by Will Antwi.
They equalised on the stroke of half-time when Owain Tudur-Jones put Andy Williams clear on the left and his fierce drive rocketed into the roof of the net.
In the second half Paul Huntington had a header cleared off the line by Mark Arber and later hit the bar as Yeovil mounted attack after attack.
But after 81 minutes the Daggers struck on the break through Abu Ogogo and four minutes from time substitute Medy Elito raced down the right to fire a low shot past keeper John Sullivan.
