Pls help me

hi good day everybody i would like to ask if there are in any instance can we say that there is sexual dimorphism in heterometrus madraspatensis.....if yes can my scorp this be visually gendered?

The first thing I noticed about this particular scorpion was the size of its pectines. They are rather large and I am hoping that means this is a male. Do you have a picture of the underside???
