Black fat tail dilemma
by exMachina Sat Apr 20, 2013 4:13 pm
Hi guys, there are different varieties of black fat tails, right? They are A. Bicolor, A. Crassicauda and A. Mauritanicus. What makes me wonder is the differences between these species. This prevents me from getting one.
To cut it short, can you guys please give at least one physical trait that will definitely give a deadway and show their differences,if possible, at early instars. For those who are new here, you can answer too, if you know. Any answer is widely appreciated.
Thanks.
Zeb

Hey Zeb.
These three spp. may be extremely hard to differentiate, specially at young instars.
A. bicolor is usually the most "common" in pet trade, the end of the pedipalps and legs are paler than the overall coloration (hence the name). Overall they are matte (except aeneas morph that are glossier but smaller).
A. crassicauda is bigger than A. bicolor and overall they are glossy black. The most reliable "trait" for ID'ing is granulation on the metasoma, but from the top of my head, I can't remember at the moment the exact granulation pattern.
A. mauritanicus is dark grey to black, and males show sexual dimorphism in chelae (A. bicolor does not).
These are in no way "definite" physical traits and until subadult, all three may be very easily confused. Your best bet will be to post a pic for ID'ing if you can get one before/after buying the specimen you want.

DolbyR has summed up the critical points.
If you are buying juveniles of these three species, make sure you get them from reputable breeders, else, wait sub-adults or adult pairs would be a safer choice.

Do you guys think that in 4i, their appearance can tell the species of these scorpions?
Because purchasing an adult specimen is too expensive, my pocket hurts

Yep, the damage is pretty high for adult pairs
Possible. They are easier to differentiate from 5.instar and above.

Do A. Mauritanicus have a full black coloration all over its body? I think this will determine my decision of what to get first.

Yes, they do. Matt black is a closer match for A.mauritanicus.

Just one?
Honestly, no matter what you take, it will be awesome. These are truly amazing scorpions!
