Morphology

ectozoon = zoon (semi-transparent) = ecto + zoon + ecto

Formally built from 'ecto-' (outside) + 'zoon' (animal) which directly yields 'external animal', but both elements are specialized combining forms used in scientific vocabulary rather than common standalone words, so the term may be unclear to average learners.

Etymology

Ectozoon comes from Greek parts ecto- 'outside' and -zoon 'animal', and the second part is the same root as zoo. So an ectozoon is an animal that lives on the outside of another animal, like a flea or tick.
