Molting of my Chilean fire tarantula (Grammostola rosea), last July. ✨
Under increased blood pressure, the tarantula begins to transport a molting hormone (hydroxylated ecdysone/ecdysterone) from the rear to the front of the body. This causes pressure to build up and the carapace (back shield) to burst open. This extends over the entire body, so that the tarantula can now gradually free itself from the old exoskeleton. This can sometimes take several hours and is therefore very exhausting for the tarantula, so that it remains lying on its back even after it has successfully moulted. In this state, the spider has not yet hardened and can therefore easily become a victim. That's why spiders create a somewhat safer place with silk threads beforehand. I've increased the speed of the video eight times because you all don't have as much patience as I do 🤪 and it makes the rhythmic movement sequences clearer.
Ecdysterone is a hormone that triggers moulting in molting animals (arthropods, tardigrades, nematodes, etc.). It is also found in plants to protect against plant pests. In mammals, it only occurs through ingestion or parasitic infestation. It also has an effect on mammals and influences lipid metabolism and protein biosynthesis. It is believed to have an anabolic effect on the muscles, which is why it is also used in competitive sports. It is believed to have no harmful effects because it is a natural part of our diet. 💪😋🥬
