The proper name for these are Hedgehogs. They were usually made of steel angles or rails measureing approximately 1.5m and 2m in length; two pieces crossed in an X form with a third resting on an angle in the crossed rails; either bolted or welded together; positioned in shallow water and anchored with concrete bases. They were meant to hinder military advances of water landing craft by piercing the bottoms of the landing craft. They were also used to hinder the progression of small and medium tanks. Their shape made the effective even when tipped over.
