All Straits and Channels (World)

This group collects the 35 Bodies of Water subcategory members that the atlas already places under its own Straits and Channels subcategory, the whole real-world population the atlas covers there. It is a single flat group, not split further by region or country, because Straits and Channels stays well under the atlas's own hundred-member threshold for a further split. It sits directly under the Straits and Channels subcategory and under the atlas's own Groups category, giving a reader a direct browse path from either the Straits and Channels subcategory page or the Groups index.
