Venus' Flower Basket (image) Brown University Share Print E-Mail Caption Despite being made essentially of glass, the skeleton of the sea sponge known as Venus' flower basket is remarkably strong -- right down to the tiny, hair-like fibers that hold the creatures to the sea floor. Researchers from Brown University have shown that those fibers, called spicules, have an intricate internal structure that is fine-tuned to boost strength. The findings could inform the engineering of human-made materials.
