| English | English The exuviation (ecdysis) of Astacus fluviatilis, the normal European crayfish, is a relatively fast process, lasting a few minutes. The preparation phase, proecdysis, in which a new exoskeleton is grown under the old one, as well as the end phase, postecdysis, in which the new shell becomes hard, last considerably longer. The time between pro- and postecdysis is called interecdysis. |
