Heliozoa = heliozoan (semi-transparent) = helio + zoa
Formed from scientific combining forms helio- + -zoa; the structure is recognizable to learners familiar with scientific vocabulary but not fully transparent to an average B1 learner.
Etymology
Heliozoa comes from Greek roots helios meaning 'sun' and zoa meaning 'animals', so the name literally means 'sun animals'. The zoa part is like the English word zoo, which helps you remember it means 'animals'. Under the microscope they look like tiny round creatures with long arms spreading out like sun rays, which is why they are also called 'sun animalcules'.
