This composite image shows Kavanagh's 2- to 3-foot aluminum scultures and a magnified image of a 0.08-inch pteropod (Limacina retroversa). Pterpods are marine snails, species of which range in size from 0.04 inches to nearly 2 inches, with wing-like lobes, or parapodia, that propel them in the ocean.
