Thanks guys, but yes it may be worth taking a look at what people have posted before you. Dont worry though, I will sort through the chaos 
@Condor, seems you are a step ahead, you are evolving from an example evolution idea that isn't in the game yet! Also the link to NESLife3 may be confusing. We are starting at the microscopic scale this time, with single cells in fact - no mouth, and too small for sailing effect.

Archaeoblobus-> Carpeolis
Additions: A thin bunch of cells devolopes to the sides of the mouth resembling a clear sheet which causes Carpeolis to sail with ocean currents collecting food along the way.
Carpeolis also developes tail like extensions which flap to help keep Carpeolis in the major currents.
Subtractions: Carpeolis no longer pulses to obsorb food but simply collects the food in it's "mouth" while "sailing".
OOC: Noob here, is this what you are looking for?
