Purple fan sponge on black base

Ianthella basta, commonly known as the elephant ear sponge, gets its name from its undulating shape. Its deep violet hue, almost black, makes it a unique curiosity in the marine world. This natural fan is perfectly shaped to capture nutrients carried by ocean currents.
Its soft and delicate appearance is deceptive—its internal structure is remarkably sturdy, proving that nature masterfully combines aesthetics and engineering. A true lesson in bio-inspired design.
Little known to the general public, it is one of those hidden treasures that only passionate (and undoubtedly fascinating) divers can recognize in the coral reefs of the Indo-Pacific. This sponge has been carefully dried and mounted by hand on a black base.
