>>Hi, I am really new to this world, I would like to know if they are difference between sulcatas and African Spurred Tortoises, Thank you

The Geochelone sulcata & African spurred are the same thing.
The different Spur-thighed tortoise is the Testudo ibera also called Greek or Mediterranean tortoise.
That's the problem with "common" names they tend to confuse people so it's the reason so many people refer to the giant African as simply sulcata.
