Giraffe subspecies are distinguished by their coat patterns. The reticulated and Masai giraffes represent two extremes of giraffe patch shapes. The former has neatly shaped patches, while the latter has jagged ones. The width of the lines separating the patches also differ. The West African giraffe has thick lines, while the Nubian and reticulated giraffes have thin ones. The former also has a lighter pelage than other subspecies.
