Non-humanoid exobiology
Non-humanoid exobiology was a localized branch of exobiology that devoted exclusively to the study of non-humanoid lifeforms. 

One of Cardassian Doctor Crell Moset's specialties included non-humanoid exobiology. For this reason, Moset was chosen by The Doctor to assist in the removal of a cytoplasmic lifeform that was attached to B'Elanna Torres in 2375. ()
