Capable of being shed, sloughed off, or cast away.
From 'exuvia' (shed skin) + '-able' (suffix meaning capable of), following standard English word formation patterns. The base Latin word refers to cast-off animal coverings.
Exuviable describes anything that can be shed—which makes it especially useful in biology for species that molt, but it also has a poetic ring to it, suggesting things that can be cast off to become new.
