Worms crawl toward the epimeral suture when de- calcification begins. By the time the suture opens most of the worms are massed against the new exoskeleton of the crab so they can remain with the crab as the exuvium is shed. Shortly after ecdysis worms can be observed migrating forward and outward until they assume a typical distribution pattern (see Table IV). During intermolt periods worms tend to be contracted and clustered in groups. On the early post-ecdysial crab, worms are elongated and can often be seen moving across calcified portions of the exoskeleton where they normally are not found. At this time worms can often be found head to tail in a single file along suture lines in the axils. Transfer at ecdysis on male crabs appears to be more variable than on Figure 1. of carapace. Worms actively crawling toward decalcifying epimeral suture on postero-latcral surface.
