Tetrapyrgos subdendrophora

The upper surface of this shell-shaped species is  a drab grey with irregular bumps or wrinkles over the surface.  Underneath, however, the gill pattern is  remarkable and appears as a coarse network of major gills and cross veins. One of nature's more attractive designs.                                                                       WESTERN II                     HOME                      NEXT
