Definition of ecdysis in English:

ecdysis

noun ˈɛkdɪsɪsɛkˈdʌɪsɪsˈɛkdəsəs

mass nounZoology

The process of shedding the old skin (in reptiles) or casting off the outer cuticle (in insects and other arthropods).
Example sentencesExamples
- Upon ecdysis, a chitinous duplicature of the exoskeleton is shed and a growth band is added to the valves.
- At ecdysis, the animal sheds the old exoskeleton while absorbing large quantities of water to stretch the new exoskeleton.
- During terminal pleateau there are a series of large pulses of circulating ecdysteroids which appear to be necessary for successful ecdysis of the entire exoskeleton.
- Considering Crustacea as an analogy, abnormal secretion of exuviation hormones in trilobite exoskeletons could also have caused irregular ecdysis and given rise to aberrant exoskeletal morphology.
- In both groups, tissue loss must occur before a critical period to permit regeneration before the next ecdysis and proecdysial processes are suspended during regeneration in order to maintain proper timing of events.

Derivatives

ecdysial

adjective ɛkˈdɪzɪəl

Zoology

Passonneau and Williams have described in the developing cecropia silkworm an 'ecdysial membrane' situated between pupal and adult cuticles.
Example sentencesExamples
- The ecdysial suture is the region of the arthropod exoskeleton that splits to allow the animal to emerge during ecdysis.

Origin

Mid 19th century: from Greek ekdusis, from ekduein 'put off', from ek- 'out, off' + duein 'put'.
