What are these black worn like bugs that are around the broken seal of the bottom of my toilet? Please tell me..

I don't know but if the seal (wax ring) of the toilet is broken you should fix it. How do you know the seal is broke. Do you mean that the bottom of the toilet is broken?

If the wax seal is ruptured that all sorts of nasty things like black sewer flies, roaches and Palmetto Bugs plus sewer gas can escape into your home.
Spray the bugs and replace the wax seal. Good luck, Tom
