Has anyone heard of this kritter Geocharax falcata ?

I've done a google but can only find references of the species name and on one page they were called "land yabbies".

Anyone?

Stuart ... best I could come up with at short notice ...Geocharax

or CSIRO Paper ... didn't read though

Unfortunately not very helpful.

One is a taxonomy paper and the other is almost a species description.

It may be that there isn't much info out there because they may not have been studied much if at all.

I think there are close to 100 crayfish species in Australia and I'm pretty sure most of them havn't been studied.

What I was after though was just some basic Zoological and ecological info.

How big does it get?
Is it terrestrial /amphibious or is that a misnomer?
What temperatures does it like?
etc.

Still hoping,

Stuart

Various Geocharax species live in Vic, Tas and SA. Working backwards from a key, they are a larger species (body usually more than 4cm long), a semi-aquatic or fully aquatic species. The rest of the description is very detailed, but they also have small and simple male genital papilla (one for the boys!)

here is an article about crays that has a pic of a cousin G. gracilis

but here, now is a page all about them, with pics and all!

Thanks Jaymie, some good general info there.

I did a google on just "land yabbies" and got some more stuff but it is not very specific.

Seems though that there a range of species that can be called land yabbies from a number of genera while most are semi aquatic some of them live on top of hills and in rainforests (ie in the forest not in a stream in the forest)

The forest species gets at least to 30cm long and hissed at some bushwealkers when they found crossing a walking track.

While all that information is tantalising ti the lack of specifics that is frustrating. For example they webpage that had the article about the foot long snake impersonating forest walking yabby didn't have the species name.

I did find a yabby forum, although that may take up a bit too much time

ps I just ordered THE book. Hope it has depth ie detail
