Marlo,

Thanks for sharing your persistent and helpful work with us.

I think it's worth mentioning that Echinolittorina interrupta occurs at least as far north as Fort Macon, NC (as IDed by Harry Lee). Porter's (1974) Atlas of Occurrence records only Echinus nodulosus and Nodilittorina tuberculata (only temporally remote records from Cape Lookout?) but no Echinolittorina interrupta, riisei, angustior, or ziczac from North Carolina.

I surmise that the range of Nodilittorina interrupta has extended into North Carolina in the last 20 years.
