Definition of cyclostome in English:

cyclostome

nounˈsʌɪklə(ʊ)stəʊmˈsīkləˌstōm

Zoology

An eel-like jawless vertebrate with a round sucking mouth, of a former group that included the lampreys and hagfishes.
〔动〕圆口类脊椎动物
Subclass Cyclostomata, now incorporated in the superclass Agnatha
Example sentencesExamples
- The skeleton of cyclostomes furnishes far fewer taxonomic characters than that of the more complex cheilostomes.
- Similar structures described in other cyclostomes appear to indicate attachment to originally flexible substrates, particularly algae.
- This extant species has erect jointed colonies, an articulated growth-form which seemingly evolved convergently with that of crisiid cyclostomes.
- The presence of a luteal like structure in cyclostomes has been observed but its function is still unclear.
- Data concerning key evolutionary invertebrate and vertebrate groups, the protochordates, chondrichthyes and cyclostomes, are essential to establish evolutionary patterns of the peptides.

Origin

Mid 19th century: from cyclo- + Greek stoma 'mouth'.
