This may look like something out of an alien film but the molting process is perfectly natural for our spider friends. π½
Spiders posses a hard, exoskeleton that is incapable of expanding. In order to grow, a spider must first release this rigid tissue.
To do so, this orb weaver first hangs upside down. Once the exoskeleton cracks open, the spider wriggles and moves before finally slipping free of their carapace. At this stage our friendβs new exoskeleton is entirely soft and pliable. They expand and grow by pumping hemolymph (spider blood) into their new exoskeleton. This stage is very dangerous for spiders as they are totally defenseless until the new exoskeleton hardens, a process that can take several days to complete.
Young spiderlings grow at a fast rate and therefore molt more frequently. Adult spiders, especially those that have reached maturity, molt much less frequently and some species stop entirely. π·οΈ
