Es and Aussies?

Does anyone else think it's possible that both Es and Aussies might actually be the same species?

I think Es and Aussies may not same species. Their charactistric are quite different. See below information.
Aussies relative information
http://www.tonycoenobita.com/species_variabilis_eng.htm
Esrelative information
http://www.tonycoenobita.com/species_compressus_eng.htm
But I think these are some speceis are quite similar
1.Rug & Es
2.Viol & Cavipes
3. Indo & PPs

They do look similar. And from what I have been reading, they are similiar in behavior, too. Very active & fast, right? Both can have stitch marks on their BP. Both have candycorn shaped eyes. Coloring is similar. I think a boat load of Es must have hailed a passing ship, migrated to Australia, and mutated!

Aussies seem to get a little larger and look to have longer leg segments. It seems fairly unlikley.

Actually think about what you are saying. It is plausible.

Australia seperated from Gonwandaland long ago which isolated it from many of the landmasses of the rest of the world fairly early. This accounts for the uniqueness of many of its inhabitants, such as koalas, emus and the like. I dont know the history of hermies (yet!), but it seems logical to assume all the hermies originated from a common source, but climatic isolation has seen mutation which gives rise to the different species. The tropical Australian climate would probably have given it some unique biological adaptions which may mean certain genetic physiological body structures gave it an advantage for the climate in which it dwells. Such characteristics are only of use in the climate which it evolved in.
Sorry, this sounds like a lecture! I took "The Histroy of Life on Earth" last semester and it changed my brain somehow!

Sounds quite clever to me Krusty, thanks for that information on Australia, I didn't know any of that.

Yes troppo, this country of ours has had some really bizarre plants and animals due to its isolation. This semester im doing invertebrate biology, so i hope i can concentrate a bit on learning more about hermies!

The adaptation theory is plausible. There are certainly other examples of adaptation on other islands. Also, animals that are unique to other islands. Madagascar has some amazing animals as well.

i'll get a first hand chance to compare this fall (or rather, spring in Aussie terms) when i go to Australia for a semester and get some. i am very interested to see how they compare to my Es!

Ok, so E's and Aussies look very much the same, same eye shape, colouring etc.
Looking at Tony's links, it appears that E's have white spots over their legs and Aussies have black spots over theirs and the spots become more pronounced as the crabs age. Do any E's have black spots or are the spots always white?

All the ones I can get to cooperate at the moment have white spots. Well. more like "Light color spots" My "Bluish" E's have seem to have blue tint in some fo the dots. It looks like whatever color the lighter, underside of the segment is, that's the dot color. I didn't pick up any of the near black Es to look.
