Red Spider - Photography

Ever seen this kind of spider specie before?
A couple of months ago, while I was in the farm with a friend spraying herbicides, I stumbled upon this beautiful and amazing looking creature.

It was my first time and I was amazed seeing it. This is a red spider with huge body. At first, I was wondering if it was really a spider but when I looked at it closely and noticed its features, one could tell it is a spider. I'm not sure if it could move fast with this huge body.
