Tarantulas, like other arthropods, shed their exoskeletons numerous times as they grow.
This is the first time a Xenesthis sp White tarantula has been filmed molting.
The entire process of molting took over 10 hours to complete, thus the video was filmed in high speed time lapse. Because the tarantula remained upright during most of the molting process, you can see the entire process in exquisite detail.
This definitely looks like some alien creature. It’s enough to give an arachnophobe nightmares.
