Ceratothoa
Ceratothoa is a genus of isopod ectoparasite parasites of teleost fish, first described by Dana in 1852. Infection by Ceratothoa can cause anaemia, lessions, 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 capri
- Ceratothoa carinata
- Ceratothoa collaris
- Ceratothoa deplanata
- Ceratothoa exigua Schioedte & Meinert, 1884
- Ceratothoa gaudichaudii
- Ceratothoa gilberti Richardson, 1904
- Ceratothoa italica
- Ceratothoa laticauda Milne-Edwards 1840
- Ceratothoa oestroides
- Ceratothoa oxyrrhynchaena
- Ceratothoa parallela
- Ceratothoa steindachneri Jordan & Evermann, 1898
