“Spiders grow by shedding their old exoskeleton and replacing it with a larger, less constraining hide, a process known as ecdysis.”
“It's from "ecdysis," a word for the process of shedding one's own skin, snake-style.”
“It might be a good idea to relate strip-teasing in some way to the...zoological phenomenon of molting,...which is ecdysis.”
“During pre-adult life, the exoskeleton is therefore renewed a number of times by the process of moulting or ecdysis.”
“Death is caused by incomplete ecdysis and cuticle malformation.”
“It inhibits ecdysis and ultimately, apolysis, the first stage in the moulting process in which separation of the old cuticle from the underlying epidermal cells takes place.”
“A less common word for the process is ecdysis (ek'dih-sis; "get out" G).”
“The last of these attributes to disappear is that of personality, and when this final ecdysis has been performed, the eject which remains is so unlike its original subject, that, as we shall immediately find, it is extremely difficult to trace any points of resemblance between them.”
“A skin of some dimension was cast in the 16th century, and another towards the end of the 18th, while, within the last fifty years, the extraordinary growth of every department of physical science has spread among us mental food of so nutritious and stimulating a character that a new ecdysis seems imminent.”
“The ecdysis behavioral program is a critical developmental period that is dependent upon appropriate water and nutrient balance, and likewise, elevated cardiac activity is a hallmark response to a variety of physiological stresses in a variety of organisms as is a circadian regulation of stress hormones”
