They have to remove large amounts of water from the tissues, as the crustacean's tissues are hypertonic to the surrounding water. A protonephridium ("proto" = "first") is a network of dead-end tubules lacking internal openings found in the phyla Platyhelminthes, Nemertea, Rotifera and Chordata (lancelets).
