What characteristic contributes to the agile movement of the Yellow Sac Spider relative to its body size?
Answer
Its legs are slender and appear somewhat elongated relative to the body size.
The physical structure of the Yellow Sac Spider's appendages plays a role in its mobility. The legs of these spiders are described as being slender and appearing somewhat elongated when compared to the overall dimensions of the body itself. This proportional length and slenderness contribute significantly to the spider's characteristic agile movement patterns. Furthermore, while the main leg segments usually match the pale yellow or straw color of the body, the very tips of the legs, specifically the final segments known as the tarsi, often exhibit a slightly darker shade, sometimes tending toward amber or pale brown.
