Water caltrops are aquatic fruits found in ponds, lakes, and slow-moving waterways. Their distinctive horns are part of the fruit’s structure and help protect the seed inside. Depending on the species, fruits can have two, three, or four projections. Although the outside looks intimidating, the interior contains a pale, firm, starchy kernel that has been eaten traditionally for generations.
