Polyzoa II
1885-1890
Frederick McCoy, a 19th-century zoologist and paleontologist, created this meticulous study of Polyzoa (now called bryozoans), which are tiny colonial animals that often look like moss or coral. Likely produced during his tenure in Melbourne, Australia, this plate serves as a visual encyclopedia of marine life from the late 1800s. The image breaks down the organisms into fascinating components: delicate, branching structures at the top resemble underwater trees, while the Y-shaped form on the left reveals honeycomb-like openings where individual animals, called zooids, lived. The large specimen at the bottom offers a dramatic cross-section view, exposing the complex internal architecture of the colony. Before modern photography, these precise drawings were the crucial link allowing scientists to share the intricate details of the ocean's hidden world.
