Are there 2 types of coconuts?

I'm curious, are there indeed two distinct types of coconuts? If so, could you elaborate on the key differences between them? Are these varieties found in different regions of the world, or do they grow under specific conditions? I'm particularly interested in understanding the potential impact these variations may have on the taste, nutritional value, and even the uses of the coconut fruit and its various products. Additionally, is there a dominant type that is more widely consumed or used for commercial purposes?
