Alright let's try this again without any copyright infringements.

The chela of Heterometrus silenus (fka H. petersii) feature sexual dimorphism. The males have a visible large tooth, females don't. This is the only Heterometrus species with this specific form of sexual dimorphism.

It is also the only species of Heterometrus being exported out of southeast Asia in large numbers (specifically Vietnam). It is the only species your local pet store will have stocked. But H. spinifer is beginning to turn up in small limited quantities.
