Talk:Hemigrapsus estellinensis

Have no published suggestions how the crab reached the spring been put forward? It seems the single most interesting feature. --Wetman (talk) 02:37, 28 October 2010 (UTC)
 * Not that I've seen. The species has been largely ignored, probably because of the dearth of material to work with. Creel stated dryly that "The present geographies would indicate a long isolation of [H. oregonensis] from H. estellinensis", but didn't suggest any mechanisms. It may be tempting to invoke a relict marine population from the Western Interior Seaway, particularly since there appeared to be a diverse marine assemblage in the spring, but Cretaceous is probably just too old (reliable crab fossils only appear in the Jurassic, for instance). It remains a mystery. --Stemonitis (talk) 08:15, 28 October 2010 (UTC)


 * I was thinking of the Cretaceous seaway: a stretch, but everything seems a stretch: crab eggs on seagull feet?--Wetman (talk) 07:21, 1 November 2010 (UTC)


 * In an online abstract of Christoph D. Schubart, José A. Cuesta, Rudolf Diesel and Darryl L. Felder, "Molecular Phylogeny, Taxonomy, and Evolution of Nonmarine Lineages within the American Grapsoid Crabs (Crustacea: Brachyura)", from Molecular Phylogenetics and Evolution 15.2, (May 2000:179-190), I'm reading "Colonization of inland habitats evolved in several lineages of the grapsoids, resulting in various forms of nonmarine life and different degrees of independence from the sea." Perhaps someone more competent )that would be easy!) than I... --Wetman (talk) 01:09, 16 February 2011 (UTC)

Fate of this page
A recent publication sequenced collected material of H. estellinensis and identified barnacles collected at the same time, concluding that H. estellinensis is a junior synonym of H. oreganus and that crab and barnacles were perhaps introduced via logs shipped by rail from the Pacific Northwest. Perhaps the bulk of the text could be moved to a new article, Estelline Salt Spring, and H. estellinensis then redirected to H. oreganus? Choess (talk) 02:01, 12 May 2020 (UTC)
