==Anatomy==
The body of the adult parasite can be divided into two parts: one part is called the "externa" where the bulbous reproductive organ of the parasite sticks out of the abdomen of the host. The other part is called the "interna" which is inside the host's body. This part is composed of root-like tendrils that wrap themselves around the host's organs, which gives its group name of Rhizocephala, meaning "root-head". Through [[microCT]] scans, these roots have been discovered to wrap around certain organs of the body, with most around the [[hepatopancreas]] of crustaceans. This area is primarily for absorbing nutrients, which would explain why most concentrate in that region. In a similar species called ''Briarosaccus'' roots were seen extending to the brain and central nervous system, which is a hypothesis to help explain how parasites like these can manipulate their hosts' behavior.
