Apparently yes: Freshwater Farm Ponds Turning into Crab Farms: North Carolina’s native blue crab population has been at historic lows since 2000. Dr. Dave Eggleston, director of NC State’s Center for Marine Sciences and Technology (CMAST) and professor of marine, earth and atmospheric sciences, looked at various methods for helping the population recover.

iNaturalist rocks!

Thanks Bill for drawing my attention to iNaturalist which has the makings of an awesome site! What is it?

Moreover,…

Believe it or not, this appears to have something to do with their circadian rhythms! Back in the 1960s and early 1970s, there was quite a lot of research published on the circadian rhythms in earthworms, mostly by Miriam Bennett.

Garden-Variety Experiment
