Definition of zooid in English:

zooid

noun ˈzuːɪdˈzuːɔɪdˈzoʊɔɪd

Zoology

An animal arising from another by budding or division, especially each of the individuals which make up a colonial organism and typically have different forms and functions.
〔动〕（群体动物中的一个）个虫，个员
Example sentencesExamples
- The individuals of the colony are called zooids and many zooids with individual siphonal openings cover the surface of the colony.
- The most integrated colonies behave like individual organisms, for the zooids making up the colony are all specialized for certain functions and connected to each other.
- The feeding zooids use retractile tentacles, called the lophophore, to filter feed and have a U-shaped gut for digestion.
- These are marine bryozoans with tubular zooids with strongly calcified walls.
- Even in the earliest stages of new growth, complete reversals in budding directions of zooids are evident.

Zoology

Large cystiphragmconstricted zooidal void spaces, a low overall proportion of zooecial space, and a low overall proportions of space taken up by cystiphragms.
Example sentencesExamples
- This requires that all zooidal walls grew independently of the rhythm of feeding polypide cycles.
- When danger threatens, the lophophore can be pulled rapidly back into the safety of the zooidal skeleton by a muscle which is said to be the fastest-contracting in the animal kingdom.
- The rest of the colony surface, including the maculae, is occupied by kenozooids with thick walls forming polygonal ridges at zooidal boundaries, the ridges occasionally prolonged into short apertural spines.
- Therefore, the two growth constants, isochronous growth levels and simultaneous secretion across shared zooidal boundaries, apply to primary cystiphragm-cortex units.

Origin

Mid 19th century: from zoo- 'relating to animals' + -oid.
