Ceratothoa
"Ceratothoa" is a genus of isopod ectoparasites of teleost fish, first described by Dana in 1852. Infection by "Ceratothoa" can cause anaemia, lesions, growth retardation, emaciation, and mortality in their fish hosts. 

"Ceratothoa" is considered to be the senior synonym of both "Meinertia" and "Codonophilus". 

Currently, at least 29 species in this genus have been described. These include:

* "Ceratothoa africanae" 
* "Ceratothoa angulata" 
* "Ceratothoa capri" 
* "Ceratothoa carinata" 
* "Ceratothoa collaris" 
* "Ceratothoa deplanata" 
* "Ceratothoa exigua" 
* "Ceratothoa famosa" 
* "Ceratothoa gaudichaudii" (previously known as "Ceratothoa rapax" )
* "Ceratothoa gilberti" 
* "Ceratothoa gobii" 
* "Ceratothoa guttata" 
* "Ceratothoa imbricata"
* "Ceratothoa italica" 
* "Ceratothoa laticauda" 
* "Ceratothoa oestroides" 
* "Ceratothoa oxyrrhynchaena" 
* "Ceratothoa parallela" 
* "Ceratothoa retusa" 
* "Ceratothoa steindachneri" 
* "Ceratothoa transversa"
