A cryptobiid was found in the blood of 2 of 9 Semotilus atromaculatus from a tributary of the Saugeen River in Ontario, Canada. Blood inoculation produced an infection in 2 uninfected S. atromaculatus but not in any Oncorhynchus mykiss, Catostomus commersoni, or Carassius auratus. The flagellate was identified as Cryptobia cataractae, based on host restriction. Cryptobia cataractae occurred as slender and broad forms (body width 3.0-8.7 microns). The length of the anterior flagellum was equal to body length, whereas that of the free recurrent flagellum was half body length. Cryptobia cataractae divided by equal binary fission that produced elongate, slender daughter cells.
在加拿大安大略省索金河一条支流的9条黑斑钝口螈中，有2条的血液中发现了一种隐鞭毛虫。血液接种在2条未感染的黑斑钝口螈中引发了感染，但在虹鳟、科氏吸口鲤或鲫鱼中未引发感染。基于宿主特异性，这种鞭毛虫被鉴定为白内障隐鞭虫。白内障隐鞭虫有细长型和宽体型（体宽3.0 - 8.7微米）。前鞭毛的长度与体长相等，而游离回折鞭毛的长度为体长的一半。白内障隐鞭虫通过均等二分裂进行繁殖，产生细长的子细胞。
