Very nice picture, I hadn't realised just how much these guys look like Heterometrus spp.

Yes peat is very good since it holds moisture well

They can all be kept in very similar conditions; on a moist humus substrate with some bark to climb on/hide under. Good ventilation is also important if you raising scorplings of these species, living in Brazil you should just be able to keep them at ambient temperature. In terms of food, any...

Lovely pictures, how long do these guys take to reach adulthood?

They are buthids so there's always a chance of cannibalism, but I know of colonies of this species of up to 6 individuals that have done well together over long periods.

Export of any fauna from many South American countries is illegal, you will have check the government information of Uruguay to be sure. It may not be possible for a hobbyist to obtain a permit.

about 9cm give or take Ventilation is essentially proportional to relative humidity in this case with high ventilation = ambient RH which is pretty constant in the UK and US. I've raised 3 broods of this species 2 of which have failed get to 3rd instar the only difference in this brood, that...

I used that method with my previous brood with poor results (though its what I generally do for tropical species), it seems that they need really good ventilation with a low ambient humidity, while still having a moist substrate. Here's the setup I use: Eric could be right though and it may...

Hi Eric I've had ~90% success with my last brood by using containers sealed with gauze rather then lids (I think you mentioned the method in an older post). It works really well for this species, though they still need to be given water often and fed regularly.

Nice picture but 3rd instar means it will be nearly impossible to ID and definitely impossible to ID with pictures.

Not at the moment, only several gravid females

Hi Unfortunately I only ever got a male specimen of this species so I could not breed them, I have bred various other Compsobuthus species and they are quite easy to breed but the juveniles can be hard to raise to maturity. If you manage to breed your C. carmelitis let me know I'd be very...

Very nice pictures, I particularly like the "Compsobuthus longipalpis", but I think they are unlikely to be C. longipalpis, I have a similar specimen that is actually C. carmelitis I think yours may be the same species.

Horseshoe crabs are Chelicerates and so are closely related to scorpions, much more so then lobsters. The likely shared a "recent" common ancestor.

Both lobsters and scorpions are arthropods, so they will share a common ancestor, though it will have been 100s of millions of years ago. I think the jury is still out on the exact nature of the deep relationships within the arthropods. However the evidence from molecular data would suggest that...

I think its great that they have passed these laws. Many of the genera mentioned are heavily overly collected and are also some of the most slowly reproducing species with the lowest population densities. It will make Opistophthalmus much rarer in the hobby, hopefully people will try to...

Definitely, Dr Prendini has been loaned the majority of the Opistophthalmus collection from the BMNH, no one will know the structure of this genus better then him or have access to more material.

Lorenzo Prendini at the AMNH is the Opistophthalmus expert, you could send it to him for an ID.

Excellent picture

I've had both adults and juveniles of this species cannibalise. They eat allot for a small species so you need to feed them allot and often to lessen the chance they'll eat each other.
