Why sea holy is described as having a jag?

The term "jag" in describing the Sea Holy refers to its characteristic jagged or irregular shoreline, which is often marked by cliffs, coves, and rocky outcrops. This topography contributes to the sea's dramatic appearance and influences local marine ecosystems, as well as human activities such as fishing and tourism. The jagged features create diverse habitats for marine life, making the area biologically rich and visually striking.
