Apororhynchus aculeatus

Apororhynchus aculeatus is one of seven species in the genus Apororhynchus, a genus consisting of microscopic parasitic worms that attach themselves to the intestinal wall of terrestrial vertebrates. The parasite was discovered in 1931, in the Berlin Museum, taken from the digestive tube of an Oriolus cristatus from Santos, Brazil, thus making it the second species to be discovered in its genus. The specimen was female.
