Ligia exotica parasitizing Godzilla grows to a total length of about 1 m due to Godzilla’s radioactivity, and it hunts the Hachimanmaru No. 5, which is sailing in the sea near Daikoku Island, and robs fishermen of all their body fluids and makes them mummified.
Note: Ligia exotica, also called sea roach or wharf roach, is a woodlouse-like isopod, a sea slater in the family Ligiidae. It is found in various parts of the world living on rocky coasts and harbour walls just above high water mark. (Source: Wikipedia)
