i know its with diffusion and like the gills and something to do with cilia, but its not clear....
Please explain.
They have two tubular siphons. The gills are located in the mantle chamber. Cilia lining the mantle chamber cause water to flow in through one siphon, flow through the gills, and then out the other siphon.
