Why Can’t Spiders Grow Bigger?
WouterIf you are an arachnophobic, you may have a hard time believing that spiders can actually grow bigger. This is not a misconception.
The truth is, spiders have a unique life cycle. This includes molting. The molting process causes spiders to increase their size.
The exoskeleton is the protective layer that holds the skeleton in place. The spiders exoskeleton is made of layers of cuticle, a type of protein. The cuticle is strong and flexible. However, the cuticle does not expand like human tissue.
As spiders grow larger, their exoskeleton becomes heavy and thick. This makes it difficult for the spiders to move. This is because the spiders cannot generate enough hydraulic pressure.
The spiders also cannot pump enough liquid into their legs to push them outward. The only way for the spiders to make their legs move is to force the fluid into their legs. Then, the spiders flex their muscles.
After a few months, the spiders will be able to generate enough hydrostatic pressure to push their legs outward. This is not enough to allow the spiders to move around without a safety line.
When the spiders molt, the old exoskeleton comes off. They then move into a new, larger colony. The spiders then increase their heart rate to pump hemolymph. This helps the spiders breathe.
The spiders also have excretory organs in their legs. They move these organs from their legs to their abdomen over time.
While the spiders do not have a large heart, they do have a circulatory system that is perfect for survival. In addition, the spiders have two simple ganglia. These ganglia are connected to the spider’s muscles and sensory systems.
