    Thank you for taking the time to do a Molt Search, and for measuring the Dungeness molts! During the data check we do for each report, I noticed that the carapace measurement for Dungeness #7 was recorded as 0 mm. Do you happen to remember what that measurement was? If not, I’ll remove that measurement from the survey.

      Hi there! Sorry about that. I believe based on the other measurements that was intended for the 50ish% molt. I dont remember what it was but would guesstimate about 80mm comparing it to the smallest molt. Go ahead and delete though if you need more accuracy.
