A pair of flaplike, mucous-covered gills collects the goodies and channels them to the animals mouth, situated at one part of the gill. On the other hand, where the parental expenditure is low, but the numbers of offspring are many, mortality is high, but the odds of a few of them surviving to adulthood is also great (think of freshwater mussels broadcasting clouds of sperm and eggs into the water, and having little other parental investment beyond their bodies making and expelling the gametes).
