A Parasite egg is the pupa stage of a Parasite, suggesting they hatch like insects. Though never seen in Metroid Prime, a wall diagram Samus can scan in Biotech Research Area 1 on the Frigate Orpheon details these eggs. They are likely hatched from the mouthike orifice of the tail of a Parasite Queen, as suggested in the Emergency Evacuation Area. The eggs have a tough exoskeleton that protects them from their mother's acidic amniotic fluid.
