Definition of chaeta in English:

chaeta

nounPlural chaetae ˈkiːtəˈkēdə

Zoology

A stiff bristle made of chitin, especially in an annelid worm.
〔动〕（尤指环节蠕虫的甲壳质）刚毛；毫毛
Example sentencesExamples
- In this respect, as indeed in their microstructure, the sclerites of Wiwaxia are fundamentally more comparable to polychaete chaetae.
- Likewise, the relative recalcitrance of various non-mineralizing tissues such as algal cyst walls, graptolite periderm, polychaete chaetae and arthropod cuticles contributes to their enhanced preservation potential.
- The microscopic structure of the setae is identical to that of the chaetae of polychaete worms.
- For example, chaetal sacks are one of the few ectodermal features of polychaetes that regularly express engrailed, and chaetae are the primary indurated elements in the ectoderm.
- Such differential preservation accords with the relative histologies of the two structures, polychaete chaetae being inherently tougher and more recalcitrant than the body-wall cuticle.

Origin

Mid 19th century: modern Latin, from Greek khaitē 'long hair'.
