The color and artistic arrangement of gyotaku prints made by skilled artists also make them valuable pieces of art. The detail captured in gyotaku, especially in historical prints, is an important source of information for scientists who want to know the size and external features of fish in the past. Gyotaku means ‘fish rubbing.’ Gyotaku is valued from both a scientific and artistic perspective. Gyotaku is a relatively new art form that developed in Japan, probably in the early- to mid-nineteenth century. This method can produce an accurate image of a fish (Fig. Gyotaku (pronounced gee yo TAH koo) is a traditional Japanese method of printmaking, which uses the whole fish. One way to document details about a fish is gyotaku. They might use a fresh fish, or they may use photographs, scientific drawings, or other kinds of detailed images–even fish fossils. Scientists work with a variety of types of fishes to do this. Scientists measure and describe the external features of fishes to identify species, assess age and health, and learn about structure and function. 4.18 shows their orientation on three different animals. Table 4.3 defines common anatomy terms, Fig. Just as a map uses north, south, east, or west to help determine the location, orientation words are useful in describing anatomy. When describing the basic anatomy of an organism, it is useful to have some common terms to help with orientation. The external anatomy of a fish can reveal a great deal about where and how it lives.

The shape, size, and structure of body parts permit different fishes to live in different environments or in different parts of the same environment. Fishes come in a diverse array of forms, many with special modifications. Anatomy is the study of an organism’s structures.
