The legs are too long to be kept in the container. While the front legs appear to be fine, they are smaller in size, the large back legs bundle and contort back on the spider. The legs themselves appear to have two joints where they are able to bend. This allows for three separate areas for the leg, an ascending, transverse, and a descending area. Of course, they could also straighten and you would be none the wiser at where this bending would occur save for the color designation. At each bend there are color bands of white and black that do not match the rest of the spider's coloration. While some legs have black, white, black bands, others consist of two bands of color or are solely white. The longest legs, which support the spider furthest from the head, are connected closest to the front of the spider.

The body of the spider has two clearly discernable segments. The smaller and most anterior of the two is where the eight legs connect. The larger segment shares the black coloration as the bands on the legs in two lines that meet at the end of the segment. The reverse side shows small red dots on the largest side closest to the point that the two segments join.

With the right light and angle, it is possible to observe the hairs on the spider's ;egs. At times the hairs make the legs themselves appear ti be segmented, but upon closer inspection of the larger rear legs it can be noted that this illusion comes from the fineness of the hairs. They are both thin and short, but stand on end.

The spider is relatively stationary when it is undisturbed. Whether this is a behavior due to its size and the confines of the container are unclear. It has been seen in more energetic states of movement where it is capable of both speed and dexterity. Again though, leg placement is hindered and the spider is not able to place/move as it desires (as far as one can tell of a spider's desires based on leg placement).

When holding the container upside down to view underneath the spider, it is possible to see two small protuberances from the head. these are most likely the pincers/fangs/grasping mechanism for the spider. Their movements and functionality remian unobserved.

Returnign to the structure of the legs, it seems that the third jointed segment, furthest from the body, ends in a thinner, curved part of the leg. It is this bowing in the leg that the spider stands upon.
