<attached image> A close-up of bullwhip kelp on a reflective surface, focusing on the structure and anatomy of its bulbous holdfast. The holdfast is prominently displayed, with a large, rounded, and elongated shape, similar to a thick, water-filled flask. Its surface is smooth and dark brown, with a slightly glossy, translucent appearance. The bulb has a narrow neck that transitions into the broader, rounded base. Cut sections of the kelp's fronds, which are cylindrical and hollow, are arranged around the holdfast. A silver fork is placed nearby, providing a sense of scale. The background features soft greenery, creating a natural contrast with the dark kelp and the reflective surface.
