What's the difference between ecdysis and shedding?
Ecdysis
Definition:
(n.) The act of shedding, or casting off, an outer cuticular layer, as in the case of serpents, lobsters, etc.; a coming out; as, the ecdysis of the pupa from its shell; exuviation.

Shedding
Definition:
(p. pr. & vb. n.) of Shed
(n.) The act of shedding, separating, or casting off or out; as, the shedding of blood.
(n.) That which is shed, or cast off.
Example Sentences:
