Galactosomum
''Galactosomum'' is a genus of flukes in the family Heterophyidae. There are currently 28 recognised species within the genus. They mainly infect aquatic birds, but often infest fish as larvae. Three species are known to use marine mammals as hosts. Description The excised spherical metacercaria is 2.7–4.9 mm long. Generally, only one is found per fish. Life cycle Some species of ''Galactosomum'' cause infected fish to swim closer to the surface and colorfully flash their underbellies. In fish, symptoms can be similar to those of whirling disease caused by the unrelated parasite ''Myxobolus cerebralis''. Gastropods hosting select species suffer from sensory impairment due to infestation. This makes these prey animals more likely to be consumed by aquatic birds, providing a host for the parasite to reach the mature stage of its life cycle. ''Galactosomum'' cannot survive in human hosts. Species *'' Galactosomum baylisi'' (Gohar, 1930) *''Galactosomum bearupi'' Pearson, 197 ...
