| Abstract: | Sticklebacks from a variety of habitats have been examined for trichodinids. Two species of trichodinid were found on fish at every site. They were identified as Trichodina domerguei subsp. domerguei and T. tenuidens , and these identifications are discussed in relation to previous observations by other workers. The tolerance to change in salinity has been examined for both species and the activity of the contractile vacuole of T. domerguei has been examined in detail. |
