You’ll find four values away from molting, pre-molt (proecdysis), molt (ecdysis), post-molt (metecdysis), and you will intermolt (anecdysis) (Timber 2007).

Ecdysis is the losing of exoskeleton, up until now the fresh new crab is quite vunerable without any coverage regarding a painful exoskeleton. Metecdysis involves solidifying the exoskeleton; the crab often consume its dated exoskeleton to include calcium supplements with the the newest exoskeleton. Anecdysis is the episodes within the-ranging from molts the spot where the crab progress times to prepare toward 2nd molt (Wood 2007).
