@Floydian_Psychology @Shadowman311 >Some species of barnacles, specifically the Rhizocephala, are internal parasites of other crustaceans. They infect their hosts, altering their biology and behavior. For example, the Sacculina barnacle replaces the genitals of its host, a green crab, and physically and hormonally alters male crabs into female crabs.
