Members of the family Cryptogonimidae are usually small and occur in the intestine and pyloric caeca of marine and freshwater fishes. Cryptogonimids do not possess any characters that are specific to them. They are recognized by the combination of characters: The body is small, with a spined tegument and some of them have spines around the oral sucker. The suckers are well developed. The cirrus-sac is absent, and a gonotyle may be present. The ventral sucker may be embedded in the genital pit. The excretory vesicle is Y-shaped. Miller & Cribb (2008) provided a review of the family.
