Ground Spider
Ever wonder what the eyes, fangs, or spinnerets of a spider look like up close? The scanning electron microscope (SEM) at the American Museum of Natural History enables researchers to magnify the morphology (body form) of a specimen up to 500,000 times and produce high-resolution black-and-white images of the magnified structure. SEMs are used to study organisms from the cellular level, to the bony 3D structure, or even an entire organism at once. One new feature of the AMNH's SEM is remote imaging, in which a researcher in, say, Japan can view a spider specimen within the microscope in New York.

In this interactive, you can view fifteen features of a generalized ground spider's anatomy (identified by letters "A" to "0" on the spider model). As you move your cursor over each letter on the model, the anatomical feature is highlighted in an SEM micrograph (image). In the micrograph, the particular feature is portrayed in orange, with surrounding features identified by letter to the key.

Explore this generalized ground spider interactive to become familiar with the complex nature of spider anatomy and morphology.
