>>>...isopods and amphipods of the US is rather
incomplete, and I keep hearing about larger ones about an inch long or
bigger.I don't know if these larger ones represent another species or merely

outsized specimens of the same species.

Pennak says that aquatic sow bugs (isopods) and scuds (amphipods) usually
range from 5-20 mm so an inch-long specimen would not be out of the
question. I've never seen really "big" freshwater isopods. I've seen some
pretty big amphipods though, especially in springs, and some species of
Gammarus routinely excede 20 mm.
