Jumping spiders shed by first creating a gap between their body and old exoskeleton, allowing them to wriggle out of their old "skin" while the new one is still flexible. This process is called molting.
Here's a breakdown of the shedding process in jumping spiders:
-
Preparation: Before molting, a jumping spider will typically find a safe and secluded spot, often creating a silken shelter or web. It will also stop eating in preparation for the energy-intensive process.
-
Separation: The spider begins to separate from its old exoskeleton. A gap forms between the old cuticle and the newly forming one. This is a crucial stage.
-
Emergence: The jumping spider then wriggles and contorts its body to escape the old exoskeleton. The new exoskeleton is soft and pliable at this stage, allowing the spider to expand and grow.
-
Hardening: After emerging, the spider will remain relatively still while its new exoskeleton hardens and darkens. This process can take several hours or even days. During this time, the spider is vulnerable to predators and dehydration.
-
Disposal: Once the new exoskeleton is hardened, the spider may eat the old one to reclaim valuable nutrients, or it may simply discard it.
In short, molting is a complex and essential process that allows jumping spiders to grow and develop. Creating the initial gap is the key step in being able to free itself from its old exoskeleton.
