Are eggs of lower crustaceans fertilized internaly or externally? This really id like to know so if somebody knows something about this it would be good. I know that higher crustaceans - malacostracans are fertilized internaly but what about so little planctonic animals like copepods or anomopods(daphnies)?
Thanks in advance.

All crustacians, big and small, evolved and primitive have internal fecundation- eggs feritilez internally
