👉 Pseudochelidae are a group of protozoa that belong to the class Chordata, specifically chordates (vertebrates). These creatures have an eight-chambered esophagus and, in some species, possess a modified gut that allows them to ferment plant materials. Pseudochelidae include various genera such as the Cryptosporidium and its relatives, which are known for their ability to cause severe diarrhea in humans.
