Echinochasmus schwartzi

Echinochasmus schwartzi is a fluke that infects dogs (Canis lupus familiaris), muskrats (Ondatra zibethicus), and marsh rice rats (Oryzomys palustris). It uses Fundulus fish as its intermediate host. Adults are similar to Echinochasmus microcaudatus, but differ in features of the oral sucker.
