ectozoan = zoan (semi-transparent) = ecto + zoan

The adjective is formed by prefixing 'ecto-' to the combining form '-zoan'; the composition is predictable but relies on technical combining forms not familiar to all learners.

Etymology

Ectozoan as an adjective uses the same parts: ecto- 'outside' and -zoan 'animal' (think zoo). So it describes animals or species that live on an animal's outer surface, for example fleas clinging to the skin.
