Surface Forms

cyclostome singular

cyclostomes plural

Morphology

cyclostome = cycle + stoma (opaque) = cyclo + stome

Both elements are Greek combining forms (cyclo-, -stome/-stoma) that are not familiar productive morphemes for average B1 learners, so the meaning is not derivable from common English vocabulary.

Etymology

Cyclostome comes from Greek parts cyclo- 'circle' and -stome 'mouth'. So a cyclostome is an animal with a round, jawless mouth, like lampreys and hagfish.
