Hello All: I was curious to know how many species of worms within Megascolecidae (particularly Amythas minimus and A. diffringens) are known to have reproducing populations in freshwater. How widespread are they and in what densities? Any insight or reference suggestions would be much appreciated. Thanks in advance.
