dnd 3.5e – What is the description and information for the Deep Orc race in 3.5 D&D?

I need a physical description and information on the Deep Orc race from 3.5 D&D.
Can someone give me information or direct me to a source that can help me?

I tried searching, but the problem is that it often leads me to the Orog which I am unsure if it’s the same as a Deep Orc because the sources lead me to Forgotten Realms pages. Forgotten Realms creatures are not the same. The elven subrace names and even the appearance of the various elf types varies as an example. Even when I search for images I’ll get the 5e orog or something from Pathfinder.
